Outlook Web shared calendars deselecting

Question

Has anyone else experienced shared calendars in Outlook web becoming deselected (unchecked)? This is affecting several in our organization. I was able to check a few calendars, then refresh Edge and all is good. Refresh the second time and only my calendar is there, the others are gone until I "Show All" and re-check them.

There are two calendars of my colleagues and one room resource calendar that I am checking.

I have been able to replicate the issue in both current Edge and Chrome, although Chrome took about 5 refreshes before the calendars disappear.

H DaneB859,

Good day!

Thank you for posting to Microsoft Community, we are happy to help you.

According to your description of Outlook on the web for business /, about shared calendars deselecting,

Based on your description, we understand that sometimes shared calendar disappeared in your OWA. As we tested from our side, it seems there is the same situation.

Based on checking, it seems more likely related to a back-end side query and to check it further required more resources, as we are from the Microsoft community team, and have limited resources, so resolving this query is recommended kindly open a ticket with the Microsoft Technical team Get support - Microsoft 365 admin | Microsoft Learn.
