Outlook asks to save when closing appointments without any change.

Question

Outlook asks to save when closing appointments without any change.

Tobias Ziegler 56

When I open any appointment in outlook calendar I have to save it before closing. Even If I did not change anything.
Any idea how to solve this?

Using M365 - Version 2105

I have the same issue. It's extremely annoying. Even if you have not made any change, it asks the question, and then it makes you doubt yourself. Has Microsoft not tested this thoroughly?

Does it occur for you if the meeting has a link and you click the link? Like a teams or zoom invite? I think this might be the issue, which still to me would mean I haven't change the invite so I don't want to see the prompt every time.

Same here. This is a constant Outlook headache, and it seems to be related to clicking links (Zoom or Teams) in a meeting appointment. After the click, it forces a save changes dialog box. Seems like this should be an easy fix, and it would save me 5-8 false events every day.

Initially I also thought it was related to clicking meeting links (being counted as "a change") but I can't reproduce the issue in that way with my current/latest Outlook client. The "put laptop into sleep mode" steps I describe above can reproduce the issue.

Are you able to reproduce this issue when clicking a link and then closing the appointment window? If yes it would be useful to know your Outlook client version perhaps. If not, then you might try my above steps of putting the laptop into sleep mode, waking up again, and then trying to close the window. In my case this reproduces the issue (on client version 2112 (Build 14729.20260 Click-to-Run))

This can be fixed by going to File -> Options -> Calendar and unchecking Show weather on Calendar. If the weather changes while the appt is open, it prompts to save changes before you can close it.

Same issue. No changes, no weather enabled, not moving from different screen scales, not going into hibernate. It still happens EVERY time I close an outlook meeting window. No exceptions. Every single time. I had to just disable the exclamation sound on my computer. I'm hosting zoom calls and this annoying sound continuously interrupts. Very annoying and clearly a bug since nothing actually does change to the meeting invite other than clicking the link to start the meeting.

This is definitely the issue. Zoom/Teams and Outlook are two of the most commonly paired software platforms in all of business - How this is not yet worked out in 2023 is beyond me. Think of all the lost productivity as people hunt for the "Save" dialog among their pile of windows to tidy their desktop. It negates the usefulness of Window's Task View, since you can't directly close a stack of Zoom invite Outlook email windows from there. You have to toggle into and out of the interface to close (and choose Not to Save) the windows one. by. one. Ouch! Plus, an unfortunate side-effect is a "boy-who-cried-wolf" effect, where you are now rapidly mass-clicking "No" on the save dialog, and accidentally lose a legitimate draft that you should have saved.
Dan Winslow 10 Reputation points

2023-04-12T14:11:05.35+00:00

This has been occurring for at least a decade. What it is 'caused by' is if anything changes in the open appointment, it gets marked as 'updated', and the standard close functionality will ask you if you want to keep the changes. The weather, your current online status, whether you are logged in or not, and maybe even what time it currently is, anything at all - if it gets changed then the whole email is marked as updated, even if whatever it was gets subsequently changed back to its original value.
What's missing is a mechanic of whether something is important or not...and probably a huge, complicated selection panel to turn on and off things you consider important or not. Plus, the ability to have things insert themselves like add-ons (zoom, etc.) and who knows what new raft of updatable items they bring along. In short, it's a very difficult problem and the huge amount of contextual data tied up in a appointment makes it even worse. Who could tell whether some random change from the weather or an add-on is important or not? Do you want it to ask you every time for every bit of changed data? That would be worse. The alternative of ignoring some changes (that happen without your intervention) versus your directly typed in changes allows for the possibility that important changes could be lost, and that would be worse.
So- It's never going to be fixed, it is annoying as heck, and that's the end of the story. My advice - close your appointments immediately after you are done with them.

I'm going to pile on here because this is a daily annoyance for me. I have 3 monitors and a ton of stuff open throughout the day. Just trying to clean up the mess is a gigantic headache. Hover over the outlook icon pinned to the taskbar, try and X out of the 20 open e-mails and meeting detail windows and get thwarted by the windows alert noise. The save changes dialogue box is hidden under 10 other open files that I have to minimize across 3 monitors in a soul crushing scavenger hunt. My question - under what circumstances would following a link in a meeting invite ever make me want to save changes? I can tell you that I certainly don't have a need, if you want to keep that functionality for some crazy edge-case, then make it a setting in the options menu. Then, you can have a thread about that with an actual solution.

@Nathan Tennant The Zoom plugin could actually modify the event's data in some way if you click a link - this may be likely an issue that the plugin developer (not Microsoft -> Zoom) would have to solve. To test that, you could disable or remove the plugin and test with Zoom appointments and clicking the link. In my case (without Zoom plugin), clicking such links doesn't trigger the issue.

Context: for some people this issue can be reproduced by opening any appointment, locking the PC, then unlocking, and trying to close the appointment window.@ Todd O'Keefe Maybe useful to specify if you used the Zoom plugin, or the Zoom add-in, if the problem is also there with disabled Zoom plugin, and if the problem also occurs with links in non-Zoom appointments? And maybe if the problem is also triggered by just locking your PC without clicking any links, would be curious about that :-)

The greater theme in all these forums where folks struggle with this issue is that Microsoft / Outlook team needs to take control of the situation. No matter what settings are set, there should be no plugin, no sleep mode, nothing at all that should impact a user’s ability to close an unchanged (ie visible fields) appointment item with a SINGLE CLICK on the X.

God, all of what Paul says 100%.

My suspicion is there are a number of issues involved with how Outlook tracks changes in calendar entries.

However, #1 is probably the "link state" updates when you click on a Zoom/Webex/Teams meeting. From an engineer's perspective, sure, something changed. But from a human understanding, I didn't update any material details in the meeting so Outlook should let me close it without a pop-up.

Given 95% of the calendar entries I actually open are meeting invites, it seems like it would be a pretty easy fix to just IGNORE the link turning from blue to purple (or whatever Outlook is tracking behind the scenes).

VERY ANNOYING... and as someone said... "boy who cried wolf" ... you get used to NOT saving items that may have actually changed. In my mind this is such a MS outlook bug/oversight I am surprised more people don't complain. It's probably because they don't care anymore and just click NO

A question and a suggestion for anyone (Microsoft?)

QUESTION = do actioning ribbon items classify as a change that needs to be saved ? (eg opening a TEAMS mtg or "Send to Onenote" create a link or change that NEED to be saved ?) I often create a OneNote page from most meetings and capture info/screenshots etc.... And I know the OneNote has a link back to the mtg ... but does the mtg need to be updated to capture the reverse link and know there already exists a OneNote page. Confused me SO MUCH!!

SUGGESTION = MS capture the reason why the item needs to be saved somehow and add it to the message (highest one only needed). eg details changed ; content changed ; time changed ; Onenote link added ; display changed (actually this shouldn't need a change) ;

Good luck

Answer 1

謙一矢ヶ部 31

I had the same problem and found reproducible conditions and a solution.
In my case, it was due to the difference in the display scale of the monitors.

If you are using multiple monitors, check to see if the display scale of each is the same.
If they are not, set them both to the same display scale.
(Right click on the desktop, "Display settings", "Size of text, apps, and items on this display")

For example, if you have two monitors with different display scales and the appointment window is opened on a monitor other than the one where the main Outlook window was first opened, you will be prompted to save the appointment even though you are not editing it.
I believe this is a bug.

Hope this helps.

Awesome! This is exactly what I had going on: three monitors, and the primary one happened to be scaled at 125%, w/ the other two at 100%. Who knew? Really appreciate the tip.

I also use 2 monitors, both at 100% display scale. (Resolutions are different though because of hardware and size differences.) The outlook windows open only on monitor 1.
So this fix would not work for me unfortunately; I still have the issue. Interesting that there are widely different working fixes for different people e.g. like turning off calendar weather as noted in another response.

Exactly same problem here with the scale option. WHen i changed it, it stopped asking to save all popups.
Annoying to have to run 100% scale on 3rd monitor, im to old to see wihtout the 125%.

Answer 2

IoTconsultancy.nl 31

I managed to reproduce the issue, as below. Key point it that the issue only occurs (it seems) when the laptop has been into sleep mode while an Outlook appointment window was opened.

Outlook version: 2112 (Build 14729.20260 Click-to-Run)
Steps to reproduce:

Open Outlook calendar, and open any appointment
Minimize all windows (e.g. use Windows key + D to show desktop)
Wait a few seconds
Put laptop to sleep mode (e.g. from start menu Power -> Sleep)
Wake laptop from sleep mode and log in again
Hover over the Outlook icon in the taskbar (small calendar window preview and appointment window preview will show), hover to the small appointment preview window and click the 'X' icon to close it)
Outlook will pop up an alert box "Want to save your changes? Yes | No | Cancel " and the user has to select something.

If multiple appointments were open, it gives the alert box for each of those.
@Jade Liang-MSFT maybe you can see if you can reproduce this issue also.

Yes i can reproduce this as well also with just 5 steps:

Steps to reproduce:

Open Outlook calendar, and open any appointment

Put laptop to lock mode (windows key + L)

Log in again

Click the 'X' icon to close the appointment

Outlook will pop up an alert box "Want to save your changes? Yes | No | Cancel " and the user has to select something.

As suggested by other members of this topic, setting my multiple screens to display scale = 100% does not work. also disabling wheater does not work..

Hope windows team can fix this asap

Confirming, the same 5 steps reproduce the problem for me too, consistently.

I get the dialog box regardless of the content and type of the meeting/appointment; empty ones, recurring, whole day, and whether I'm the owner or was invited.

I do not get the dialog box with other outlook items (email messages, tasks, contacts).

Also, this is not related to the screen scaling (I have three monitors and tested multiple combinations of scaling, none of them affected the problem).

I think the "Sleep Mode" thing and the Zoom link thing are likely two independent issues. I suspect the Zoom link issue is more prevalent and should be addressed more urgently.

Answer 3

Richard Rydström 11

I've had the same issue since Office/Outlook 2013 and I'm now running O365.
I do believe this issue is related to using the sleep/hibernate feature. I've been using hibernate for years and it seems as if that is what's causing this issue.
Should be fairly easy for someone from Microsoft support to re-produce by simply opening a calendar item (most of my invites are with a Teams online-meeting link), hibernate the computer (using Windows 10), start the computer again and then try to close the opened calendar.

Keeping my fingers crossed this annoying "bug" can be solved.

Here is the solution that worked for me. In Outlook, you simply need to go to file>options>add-ins>hit go, then uncheck the "outlook social connector 2016" add-in.

I doubt this is the solution for everyone. I have this persistent problem and I DON'T have the "outlook social connector 2016" add-in.

Hi @Tobias Ziegler ,

Did it occur on a specific appointment or all appointments/meetings in your calendar, if it occurred on any specific items only, are there any differences between them and others? And whether you have input and then delete any words in those appointments?

If you just open and close the appointment, I have tried to test on my Outlook 365 version 2105 (Build 14026.20246), but found it could work normally when I open and close the appointment/meetings. In order to further confirm if your issue is related to your account or client, it's suggested to log into your web mail to check if the issue could be reproduced there.

If it could work normally on your web mail, the issue may be related to your client itself. Based on my research, any add-ins may cause it, it's recommended to restart your outlook in safe mode to check if the issue has any differences(Windows + R >type "Outlook.exe /safe">enter).

If you could work normally in safe mode, it's recommended to disable your add-ins gradually to check which one causes the issue(File>Options >Add-ins>COM add-ins,Go>uncheck the add-in to disable it).

If the issue still exists, considering corrupted outlook data file or profile may also cause it, it's recommended to create a new Outlook profile for testing(Control Panel>Mail>Show profiles>Add>readd your account).

If your issue has any update, please feel free to post back.

This is incredibly simple and easy to replicate. If you leave a calendar invite open past the date of the invite, closing it asks you if you want to save changes. It's infuriating Microsoft hasn't fixed this stupid bug in any iteration of Outlook. It's been a persistent issue in every iteration of Outlook I've ever used.

@Josh Horton Interesting, when you say "leave a calendar invite open past the date of the invite" it sounds like you open it at the date of the invite (e.g. when the online meeting starts). And do you mean leaving the PC on until a future date (e.g. the next day)? Or do you rather switch it to sleep/hibernate mode, then wait for the next date, and then wake up the PC from sleep again? In the latter case (sleep or hibernate) the issue can be reproduced without waiting for the future date - see my post below of Jan 27 2022.

Something like this, yes. It's always happened on my corporate machines. When I go home I don't always remember to close out the calendar invites over the past few days; the system gets locked but not restarted.

I'm just surprised this hasn't been resolved. In 15+ years this has always been a pain in the neck.

I don't understand the design why add-in causing the issue, can outlook use different way detect changes? It's a decade old bug and I'm amazed MS never fixed it.
