Hi Tom, we just found a workaround that seems to solve the issue for us.

  1. Open settings
  2. Change username to an unknown user - ie add an extra letter to the username and domain name
  3. Save and Exit
  4. Let the login fail
  5. Open settings once again
  6. Change username to the original name and correct the domain name
  7. Save and Exit
  8. Wait for the SRS to update the calendar

 

Very strange indeed. Since this happened with all our SRS's at the same time - could it be that some kind of token has expired and needed to be revoked? Just a reboot or logoff/logon did not solve this. We have to log in with a different user to make this work.

We are running on version 4.0.31.0, Win 10 Build 16299.726.

*update*

 

migrated a meeting room back from exchange online to on premise and still doesn't get the EWS calendar info. However, create brand new account on premise (never been online) and works fine.

Did packet capture for the exchange online mailbox (which has now been moved on premise) and it still goes out to the internet and communicates with ADFS/Exchange online.

 

does anyone know if SRS uses Legacy authentication to communicate with Exchange online? I don't think it uses modern auth

    Did you ever find a solution to this? I am experiencing the same issue. I would be very interested to hear what you found out especially with regards to modern authentification etc.
