User Mailbox migrated to EXO, still no calendar in Teams

All the research I've done has shown that while the organization is in Hybrid mode with Exchange 2013 on-prem, the on-prem mailbox users will not be able to access the Calendar and some other functio...

    Frustrating I agree, but I think as things stand all you can do is wait I'm afraid.  Not aware of anything that would speed up the process.

Yeah as Linus said check the web teams client and see if it’s there. It’s likely just signing out of teams and back in could force it to check to load the calendar tab. Restarting computer and Teams isn’t quiet the same as a sign out and in but something else to try to try and force it to be quicker as it should not take that long to update if your migration is complete.

Another thing when you do your migrations in exchange side you are completing them once it’s done migrating I assume?

    Thanks for your responses. The synchronization in the background, and not-so-instant nature of O365, is understood. The issue I have is the inconsistency with the timeline. Some users are instant, others take 24 hours, others have taken multiple (so far as many as 5) days. My first test user was instantaneous, but that has not held true for any subsequent migrations even with the same account. I really hope I don't need to tell my ~600 users that after migration they may need to wait up to a week, or not at all, for something as simple as calendar access to be granted. I have to say I'm a bit shocked by everyone's position that this is acceptable.

     

    As for troubleshooting, we have attempted all of the following to move it along without success. This indicates to me it's a backend issue. 

    • close and reopen application
    • sign out and sign in
    • reinstall of Teams on PC (system wide installer)
    • We have also investigated MDM as a possible contributor, and have ruled it out

     

    I hear your point about it being enabled on the client. However, the behavior is the same across all access methods (PC, web, native iOS). This is "the big feature" that really makes Teams shine for them post migration because there is so much integration between EXO and Teams. It's very frustrating that Microsoft can't make it reasonably consistent. In many companies, a frustrating initial experience can be a death stroke for an application before it even gets started, and that is my fear here. We are already combating the, "Why do we need Teams when we have Skype" people. This will be my users first experience with Microsoft 365 as a SaaS app. We have deployed the CTR apps for years with on-prem services. Also, sometimes a Friday night migration is not appropriate as not all businesses stop for the weekend, or have a consistent 5-day 8-5 M-F work week. 

     

    In answer to the specific question about completing the batch, yes they are being completed manually, so far within an hour of the initial sync completing.

     

    I appreciate the responses.
