Unable to expand mail-distribution group with more than 100 members, in Outlook calendar section

[soerenporse]

In our organisation we have a mail-distribution group with slightly over 100 members.

Our users can add that group to their list of calendar groups, but are unable to expand it - getting an error as shown in below screenshot:

Other groups with fewer members are expanded without issues.

So now I just want to know if this is a known limitation "by design" or if it should be possible to expand such groups with more than 100 members?

It's by design. Do you really need to see all 100 calendars? Just add the user directly instead.

Thanks for clearing that up. I just find it strange that this is not stated clearly anywhere...

I think the user does not want to show all 100+ calendars at the same time - he just wants to be able to expand that particular DG to see a list of every person who is member of it (the group in question contains all employees in a specific office).
