Calendar in Teams not showing for some users

[neonetman]

Good afternoon...

 

I have been trying to get the calendar tab to appear for users in MS Teams.. So far, I have:-

 

• setup hybrid Exchange, and migrated a number of users over to the Office 365 for email
  
• Logged onto some test users and seen the calendar tab is there
  
• Logged onto myself and another member of staffs teams, and there is no calendar tab..
  
• Done a compare and contrast of the 4 accounts (all created in AD and synced via AD Connect)
  

 

The only difference I can see is that the 2 accounts that work are showing a directory status in Teams/Users as "Online", whilst the 2 that don't are showing as "On Premise".

 

Can anyone explain to me why they have different statuses even thought they were created the same way, and even more important, how can I change the directory status to "online"

 

Thanks in advance (yet again)

The calendar tab in Teams will only show for mailboxes that are on Exchange 2016 CU3+, or are on Office 365.

 

The ‘Directory Status’ column in Teams admin center tells you where the user account was created. What version of Exchange are you running?

We are running a hybrid of Exchange 2016 CU12 with Office 365. The mailboxes I've tested were all created in Active Directory on premises, then migrated to Office 365. (in fact all our accounts are created on premises, yet Teams shows a mix of directory statuses, which I can't explain)

 

Despite this, 2 show the calendar (and have directory status online), and the 3rd doesn't show calendar (an d has directory status on premise)

 

Would the CU version on the edge server matter, as that doesn't appear to have been updated to CU12
