Connect Exchange calendar and Office365 calendar

Question

The following technical setup:

• • E-mail runs via Hosted Exchange
• • Microsoft 365 is used in parallel

The problem: When I receive an appointment or notification via Teams (i.e. Office 365), they do not appear in my Outlook calendar (and vice versa).

In the end, the same mail address always appears to the "outside" - but apparently two systems are addressed behind it, which leads to the problems.

How can this be synchronized or in general be solved?

Hi @ Its_winter_time ,

Just want to confirm that calendars for Teams in M365 need to be synchronized with mailbox calendars hosted in your on-premises Exchange server?

 

For cloud users, the Calendar section in Teams is connected to their Exchange Online (EXO) calendar.

For calendar access to work with on-premises mailboxes, users with on-premises mailboxes must be synchronized to Azure Active Directory. You need a hybrid deployment for on-premises Exchange Server to enable interaction with Microsoft Teams.
