User Mailbox migrated to EXO, still no calendar in Teams
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.
Hi MattShafer
As ChristianBergstrom says, if mailboxes are on Exchange On-Prem, then there is some work to be done, but once migrated to Exchange Online, the calendar option should become available.
How long has it been now since you migrated the mailbox to Exchange Online please?
We had a test account that experienced this first. We had moved the test account up to EXO, and had full teams functionality immediately. Testing functionality, we moved it back to our on-prem servers to confirm we could do it (business req); then moved it back up to EXO successfully. After this migration it took 4 full calendar days to appear, during which time I ran the mentioned support case. Support closed it claiming something I did in troubleshooting resolved the issue.
Yesterday I migrated my account as the first LIVE user account to move from on-prem to EXO. Nearly 24 hours later, almost to the minute, from my migration it has appeared without warning. I migrated another user later in the day yesterday. That user's migration ended up completing around midnight last night. They still do not have the calendar, but do have other EXO integrated apps like To-do. Hopefully when they log in tomorrow morning, they will have the calendar.
It's a bit anticlimactic considering this is one of the key features users will be looking for (that we're missing on EX2013). I'm really looking to see if there's any PowerShell cmdlet or script I can run to help make this more consistent.

PeterRising Thanks Peter! As far as I know all should be good when using EXO but just had to ask for a second opinion. Appreciate your reply (as always). MattShafer Hopefully it's nothing else than waiting for it to populate then. Cheers!
MattShafer Sounds like a delay (something synchronising in the background) and that users should see the calendar in Teams after 24 hours. If you download the log files for Teams (CTRL+Shift+Alt+1) you should see that EnableCalendarApp is set to true when Teams know that there is an calendar.
You could also try the web client for Teams, sometimes it updates faster. https://teams.microsoft.com.
And for next time, we are always recommending doing migrations and larger changes on Friday afternoon since there is almost always a up to 24 hours (or more) delay in Teams/Cloud services.
