User A comes to me to advise they cannot expand a certain Distribution List.
Checking this on outlook we also encountered the same error:
There are some areas to check:
Hidden from the GAL
- Check that the Distribution List is not hidden. You can check in AD or Exchange:
Okay great, so the hidden field is not set.
Now in AD lets go and check the Group Scope:
From what we can see here it is set to Universal. Lets change the Group Scope to Global.
Now from the outlook client we are able to expand the group.
Hope it helps.
