Calendar doesn't show meetings anymore and constantly leaves the team in Teams.

Theo 0

We have a shared mailbox as "projects" which also has a license for Teams.

on a shared PC it is logged in and is part of the team for Teams.

we used to invited projects to meetings from our personal accounts, then if you went through to the meeting room it would have the meeting on the calendar.

now when you invite projects nothing appears on the calendar. when you open Teams half the time you have been kicked out from the team and have to click join again to see all the channels. Occassionaly you will see a meeting in the calendar but 10 minutes later and it could vanish.

I dont understand what has changed in functionality but its infuriating that it doesnt just work like it used to.

Hi @Theo

Have you tried to invite other mailbox to check if the issue still exists?

Does anyone else have the same issue?

all other members can be invited fine. we all have an issue with inviting the projects member. the calendar just doesnt work properly anymore and the account is constantly removed from our team and having to rejoin when you open the Teams app on the shared PC signed in as projects.

Hi @Theo

Based on our research, shared mailboxes aren't intended for direct login. Keep the shared mailbox account in the Disabled state, and avoid resetting its password or signing in by using the shared mailbox user account.

Calendar doesn't show meetings anymore and constantly leaves the team in Teams.

Firstly, you need ensure that the delegate who organizes the meeting has Full Access permission to the shared mailbox. Next try to use the shared mailbox calendar to update meetings. Finally, you can try that the meeting can be created by a delegate by using the shared mailbox calendar, and then delegates can add co-organizers to the meeting.

sorry i dont understand. how do i access the shared mailbox calendar in Teams if i'm not suppose to log in as the shared mailbox?

we used to just have the shared mailbox > sign in on Teams > do nothing but access the calendar in Teams to access meetings in the meeting room.

now we would need to log in as a user and access the shared mailbox calendar? which means might as well just log in and use our own calendars, no?

Hello @Theo

Here is the official Microsoft documentation I found：

https://learn.microsoft.com/en-us/microsoftteams/troubleshoot/meetings/teams-meeting-with-shared-mailboxes

Hope the above information is helpful for you!

based on all of this, it suggests it should never have worked the way its been working for a good 3 years :/ only the recent Teams updates have screwed everything up. It's also causing problems with trying to make meetings now. says its failed but sends anyway or just straight up fails to make meetings multiple times in a row.

beginning to regret ever having come to Teams. so hard to navigate through MS.

You can send your feedback in Microsoft Teams, and then select Help at the bottom lower-left of Teams and then choose Suggest a feature or Give feedback to tell us what you think.

Meanwhile, to solve this issue/bug more quickly, we also recommend you give the feedback in Teams UserVoice and help us make improvements and build new products. Many features of our current products are designed and upgraded based on customers’ feedback. With requirements like this increase, the problem may well be released in the future. Thanks for your understanding and support!

thanks, ill take a look at those two options as well. this was one of the first pages that popped up when trying to find Teams support on google.

the calendar was temporarily working again for a day but then went back to removing meetings.
