Shared calendars in O365 now showing as individual calendars as opposed to merged

TJ 0

Since this morning, on the online version of Outlook Calendar, I can no longer view shared calendars together with mine. For every new calendar I open, a new window appears parallel to my own calendar. This is making my work impossible. As Project Manager I frequently have to schedule meetings with upwards of 10 participants. It is impossible to find an available spot with this new view. Please help me get the old / merged view back.

I want to be able to open as many calendars as I want an have them overlap with mine.

And yes, I know I can use the "scheduling assistant" tab in the new event window, but I don't find that functionality as useful, as I have to scroll day by day, as opposed to having a weekly or monthly view for example.

Hi! Sorry to hear that you have troubles with this situation, to better understand the situation, could you please share a screenshot of how it looks currently and is available one of how you expect it to look?

Hi, thanks for the quick response. Currently each calendar I select opens a new "window" next to the other

So if I have to schedule a meeting with ten people, I have to look into ten different calendars, and the more you add, you also have to start scrolling to the right because they don't all fit in the same view.

Previously, I could see everyone's meetings overlapping with my own, in one single view. Each person's calendar had an assigned colour, helping me identify which meetings belonged to whom. This enabled me to quickly find an open spot.

While researching this change (before submitting my question) I saw a lot of comments from people who prefer the new view. I understand that, but maybe there could be an option to select whether to view calendars in overlap or separately.

Ideally, and the way it was before, it would look something like this, with each colour being a different person's calendar.

Hello TJ,

Thank you for sharing the details and screenshots, this behavior is due to a recent change in Outlook on the web. When multiple calendars are selected, the default view is now Split view (each calendar in its own column). The good news is that the overlay/merged view is still available; it just needs to be toggled back on. If you're using New Outlook or Outlook Web:

Go to Calendar.
On the top toolbar, select View > Split View.

If you're using Classic Outlook:

Go to Calendar.
Choose View > (three dots) > Overlay.
Click "<-" from right calendar (in the heading of each calendar) to merge it with left calendar.

Let me know if you need further guidance.
