MS Teams missing Calendar Tab

Hello,

since I have installed Exchange 2019 (core) in our Exchange 2019 enviroment. I have problem with someusers (dont know, what is different...), cause they are missing calendar tab in MS Teams. We have HCW setup, Azure AD Connect.

Testconnectivity sayin:
Analyzing the Teams middle-tier user service properties settings response.The user mailbox is marked as undiscoverable by the Teams middle-tier service.

If I tried in web browser this url:
https://outlook.office365.com/autodiscover/autodiscover.json?Email=UserA@CompanyOrg.com&Protocol=EWS&RedirectCount=5
Iam redirected to:
https://autodiscover.CompanyOrg.com/autodiscover/autodiscover.json?Email=UserA%40companyOrg.com&Protocol=EWS&RedirectCount=7

and gets: {"Protocol":"EWS","Url":"https://autodiscover.companyorg.com/EWS/Exchange.asmx"}

so it shoud be discoverable mailbox or am I missing something? Reddirect works good for Protocal=REST too.

Thanks for any advice, I tried a lot of articles on internet but no solution so far. :(

Hi @Radje ,

Looks like the mailbox was not properly set to interact with Teams. Because you are using the on-prem mailboxes in a hybrid environment, you need to do some preparations:

See the official documents to get help: Requirements to create and view meetings for mailboxes hosted on-premises

And for your issue, please check the ideas in this: Troubleshoot Microsoft Teams and Exchange Server interaction issues
Navigate to the second part: Troubleshoot the Teams calendar App issue

Also, please check the More options button and see if the calendar was there:
