Time indicator bar in Microsoft Calendar is not updating

I have internal customers facing the same issue with the Outlook version 1.2025.806.300 (Production), Client Version: 20250808005.08.

I don't have this issue in the Client Version: 20250808005.07, it started on 20250808005.08.

Every single user in my org is having this issue as of the last few days... Restarting only fixes it for a few hours and then it locks up again. This is real annoyance for us, causing missed appointments and scheduling confusion.

I am having the same issue with Outlook. This is preventing notifications for appointments coming up as they should. Windows is keeping time properly.

In the attached image you will notice the system time in the bottom corner is 2:10PM. The current meeting began at 14:00 (2:00PM) but the notification thinks it is 33 minutes in the future.
I have only noticed this problem cropping up in the last week or 10 days.

Exactly. I have to shutdown Outlook and restart but it happens again almost immediately.

I am also encountering this issue consistently:

The actual time for the screenshot was 1:45pm.

Restarting the app refreshes the current time but it quickly desyncs.
Only started recently.

All troubleshooting steps applied, but no change.

Microsoft Outlook Version: 1.2025.806.300 (Production)

Client Version: 20250801002.12

WebView2 Version: 139.0.3405.86 (Stable)

I'm also experiencing this issue on Windows 11.

Microsoft Outlook Version: 1.2025.806.300 (Production)

Client Version: 20250801002.12

Having the same issue, tried all the proposed work arounds and no luck. i can't close and reopen the app every 30 minutes to stay on track. I rely heavily on this.

Definitely a new Outlook bug that Microsoft needs to address. Same thing started happening within the last few days.

This is a super annoying issue in the NEW Outlook.

The calendar shows a blue line for the current time but it is lagging about 3.5 hrs for me:

I also have this issue and just missed an important meeting.

I have the same issue started a few days ago and it's very disruptive to my schedule. I tried deleting the cache, same issue. Very frustrating

Facing the same problem. Microsoft support's answer is exact replica of ChatGPT's answer so definitely less hopeful.

I use outlook app frequently and I noticed this issue since a couple of days ago. The issue is not appearing in the Web Application version. Time zone setting in my computer and the outlook app match.

I am also experiencing this issue.. Our support team opened up a ticket with Microsoft.. This just started occurring last Monday - 8/11 or Wednesday 8/13. The timebar in the NEW Outlook has begun to slowly drift off of time.

The timebar in new outlook gets worse as the day goes on, and the associated notifications DO NOT work properly as the timebar drifts off.

We have tried EVERYTHING listed above.. EVERYTHING.

1.) The issue does NOT occur in Outlook Web

2.) The issue is not occuring on my home laptop in new outlook.

3.) We have checked all windows settings for Time and Time zones

4.) We have checked all outlook settings for time and time zones

5.) We have reset and repaired New Outlook.. no change in timebar error

6.) We have uninstalled and reinstalled new Outlook - no change in timebar error.

7.) Exiting new outlook and reloading it - SEEMS to reset the timebar, but only temporarily.. The issue re-occurs within 30 minutes after going back into the app.

Currently I have reverted back to Classic outlook and I am using that... the timebar issue is not presenting on Classic Outlook.

This issue is ONLY occuring on my work laptop, with my company domain and only in New Outlook.. The issue started around 8/11 or 8/13. The only software update that occurred around tha time was a Windows Defender update.. That was it..

Nothing else was installed to the laptop.

My New Outlook Version is: 

Microsoft Outlook Version: 1.2025.806.300 (Production)

Client Version: 20250801002.12

WebView2 Version: 139.0.3405.102

Session ID: 9b72af4a-f686-1343-9b05-1aecd569cf13

Release Channel: Targeted Release

In your example you have multiple time zone configured to show in the calendar. I do as well. Can anyone else confirm that they too have multiple time zones shown? I wonder if that is a common thread?

I removed them all and tested and still got the same results.

We've been having the same issue here. Repair does not resolve the problem.

Same issue here. Have a very upset client about the issue. Any ETA on a patch / software update to fix the issue?

Adding to the mix @microsoft, our team is experiencing the same issue, this seems like a bug that needs fixing please!

The bar ends up being behind, but worse, my reminders end up being way off--I just had one fire at 9:45am (15 minutes before my 10am call) but it said the meeting was in 24 minutes. So clearly something in the system knows what time it is.

Same issue here. I had multiple time zones as of early July and then removed those from my OS and Outlook. This issue started last week for me. So, it may be something with time zones, but it seems persistent even if time zones have been removed (or it might not be related to time zones at all).

Same issue here, the time indicator line updates on the web version like normal but in the new outlook desktop application it seems to get stuck

I am also seeing this issue which is hugely inconvenient. Please fix this!

same issue and proposed solutions not working. hope fixed soon

It is even worse, because the time is hanging in outlook, the listed emails are affected as well. It's a freeze of the time in Outlook and in my case now it is still frozen on the date of yesterday causing emails that were received yesterday still being displayed under the "Today" grouping and emails received today are displayed above the "Today" grouping as if they are received in the future.

I need to close outlook and open it again to temporarily get rid of the issue.

This problem is forcing me back to classic Outlook. Not a good look from Microsoft.

It seems you can still use the new Outlook as long as classic Outlook is open in the background. If both are open, the new Outlook seems to stay in sync. (At least that is what I have found.)

Yes, this is ridiculous. I missed a meeting. Would prefer you remove the bar if you can't fix it.

Can you please look at your last release, and fix this issue. This just started a week or so ago and It's VERY disruptive to your customers. I've done everything suggested and it works for a very small amount of time and then it's off time again. At this rate, I will likely have to go back to old outlook client. I do not like email in web browsers.

A couple of our users are experiencing the same issue. Tried one of the suggestions where both Classic and New Outlook are opened to make them sync, but only Classic Outlook is correct on time.

The problem for me is that since the time indicator is not correct, then I am not getting notifications for meetings. I have been late to several meetings now since this started happening. I really hope this gets fixed soon.

Since my company rolled out 2025-08 Cumulative Update for Windows 11 Version 23H2 for x64-based Systems (KB5063875), the issue seems fixed. It is strange, because the patch notes do not seem to have any relation with this issue at all. I'll keep monitoring. I'm glad it's now officially flagged at MS though.

same problem. stop start of Outlook only temporarily fixes the issue.

Same issue. Only a full close/re-open of New Outlook temporarily resolves.

Multiple time zones in taskbar clock, but single timezone in New Outlook Calendar -> Timezones. "When I travel" box is ticked.
