Outlook does not correctly expand AD groups in recipient

Exchange Server 2013, Outlook 2010/2013. The Outlook feature that allows entering an Active Directory group as an email recipient or calendar attendee recently stopped showing all groups or individuals inside it after clicking the “+” or double clicking the group name. Instead, it only shows the first entry of the next level. The distribution still works correctly, but expanding the list, for example to view everyone’s shared calendar, does not. For example, “Everybody” is comprised of “contractors” and “employees”. Expanding “Everybody” should show both groups as the next level, but only “contractors” appears. Similar behavior for groups within groups. However, everyone within the group (such as “everybody”) does receive the email, so the actual distribution is working. It’s just displaying the expansion that isn’t working correctly.   This worked fine a few weeks ago - we don't know what changed.

Make sure that the invisible group is member of GAL or it is not hidden from GAL.

Thanks - that seems to work for some of the groups.  All are Universal security groups.  Some of them refuse to let me change the setting (error: not a manager of the group) even though I am listed as a manager and/or owner.  I have no idea how this changed all by itself.  Any ideas on the permissions issue?

Try to update the settings using an Exchange Administrator account. You need not be listed as manager of the group if you are trying to change using an admin account. Also, these universal security groups must be mail enabled already.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

I found "Exchange Organization Admins" - is that the security group?  I added "Domain admins" to that group and will try this again.  I found the EMS command for forcing updates - I may try that as well.

Great. Yes, thats the security group which will have access to all Exchange groups

I ran Set-DistributionGroup -ForceUpgrade for all groups.  Should that do it?

You are upgrading your groups from old version by running this command. What do you want to do with the groups?

I want to be able to change the "Hide from GAL" checkbox that requires upgrade to change.  What is the reason not to upgrade?

dvanakenAuthor Commented:
Thanks!  That did the trick - once the groups were upgraded, the GAL checkbox could be changed.
