Hello.

 

I have one user that is unable to create Teams meetings for another user in Outlook.  They have full access to the other mailbox (they are both hosted on-premise with Exchange 2016) and can schedule regular meetings, just not Teams.  It shows the following message:

 

Sorry, but we cannot connect to the server right now.  Please try again later.

 

The error message is useless as it doesn't say which server it is trying to connect to.  I have checked our OWA and ECP, everything functions perfectly.  Has anyone else seen this before and fixed it?

 

Thanks.

@bec064 thanks for the reply.

 

Yes, as far as I can tell everything required is setup.  We have been using Teams happily for some time but I think this is the first time we have experienced this issue with 

 

For info, we have Exchange 2016 CU17 hosted on-prem and no mailboxes in the cloud, they are all on-prem.  The hybrid setup has been in place for some time.

@Dai_Webb So only for one user? In that case I would focus on the client (new .ost / new profile etc.) Perhaps another member has seen this before and will reply.

@bec064 

 

Sorry for the late reply.  No, it seems to be all users - I've just tried it with a few more people and they all get the same message.

@Dai_Webb Hi! Then I would walk through this step-by-step https://docs.microsoft.com/en-us/microsoftteams/exchange-teams-interact#requirements-to-create-and-v...

 

Note the "To enable calendar delegation for these users" section as well.

@bec064 great suggestion, I've got further now, thank you (it was the step 2-3 part - I didn't do this previously as we don't use Skype for Business).  Now I get this error, which appears to be permissions related, but the user has full access to the recipient's calendar:

Any idea how I get past this one ?

 

Thanks in advance.

@Dai_Webb Hello! Well done. I believe you could be missing the -SharingPermissionFlags "Delegate" but I'm not sure if you can use this as it's EXO only.

https://docs.microsoft.com/en-us/powershell/module/exchange/set-mailboxfolderpermission?view=exchang...

 

But delegate can be set from within the Outlook client using "Delegate Access". Try them both and let me know? Thanks.

@bec064 you're right, the SharingPermissionFlags parameter doesn't exist on-prem.

 

I've tried delegating permissions through Outlook (logged into Windows and Outlook as the user sharing the calendar) but that hasn't helped, it still gives the same permissions error.

@Dai_Webb Thanks for the update. I noticed the error message is described here, so please verify the settings one more time.

If it still doesn't work I suggest you open up a support ticket with Microsoft.
