Can't add group of calendars in Outlook

Hi all

We have, for a long time, had a mail-enabled security group, containing all our meeting rooms, in O365. Then in Outlook calendar we select add calendar -> from address book and then select the group. Normally this would add a calendar group containg all the calendars of the members of the group - and even update the members if we add new meeting rooms etc. making it easy for all employees to always have access to all meeting room calendars.

For some reason this function has stopped working recently. Now, when I open the group I get the error: "We can't add the calendars of everyone in this distribution list (name of group). Please add each calendar individually."

 

It still works on older computers - mine for example. But it does not work on any of the new computers I have set up.

I have tried to create a new group and only add one meeting room - it does not work either.

Any suggestions? - it's driving me nuts 🙂

  • RuneGL I had the same issue. Try turning off shared calendar improvements.

    Go to account settings in Outlook. Then the Exchange account settings. Go to More Settings. Then Advanced. Uncheck "Turn on shared calendar improvements" under Microsoft 365 features.

    Hope this helps

    Hello, is it possible to use a distribution list to add a bunch of people's calendars through Outlook WEB?
    On the desktop version of outlook this functions as expected:
    you select the distribution list from the address book and every single person is added individually.
    But once you do the same thing on the web, it just adds a single calendar with the address of the distribution list, which is not at all what i want.

      i have the same problem/question.

      At the reception, we have a AD-user logged in with no M365 license, but we want to see all calendars of the colleagues in that particular building. The user who is in charge of reception that day logs in to the online Outlook web app with his/her account on the pc (with only an AD-user account).

      No calenders from de distibution group members are visible, or no posibility to add them.


      in outlook desktop app on the laptop of the person, we can see all the calenders.

      Thank you so much. We work in a hybrid environment and the distribution list we wanted to add to outlook is an old list from our on-premise server. Eventhough it's synced to M365, it seem to be the bottleneck. By default Microsoft enables this feature mentioned in your answer.

    We are having the same issue - it looks like its the computer somehow that makes the different - I have just reinstallede office on my work PC and is able to add new - but on my labtop i cannot !!

    But its not only Meeting Rooms list - all Distribution Group give the problem.

     

    I have tried contacting MC - there first reply was that it was by design but I ask them to reconfirm. Still waiting for reply.
