Just for the record - we are also experiencing the same thing now. Suddenly (after the weekend) none of our SRS-rooms are able to get the calendar info.

We are running SfB Onprem as well as Exchange Onprem.

We are still investigating this, but just thought I should chime in and add 1 more to this case.

thanks for the reply, I still haven't managed to sort our issue yet.

We have gone as far as testing the room accounts on Skype for business App on computer (win 10) and testing to see if the meeting info comes through... all working fine... so it seems specific to SRS but we haven't got to the bottom of it yet...

    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.
