I've seen these before and I can't remember if it was security or something
else. But that's what I'd check first.

Subject: [NTSysADM] Distribution Group not appearing in ADUC user properties
Exchange 2010 SP3 UR14, Windows 2008R2 SP1 AD.
The Distribution Group is Universal.
The Distribution Group is visible in the EMC in Exchange.
The Distribution Group is visible in ADUC on the DC in the OU.
Members can be added if you open the properties of the Distribution Group in
either the EMC or ADUC.
If you open the properties of the user in ADUC and try to add the group there
it cannot find the group.
The group is hidden from the GAL, but I can see other distribution groups that
are also hidden.
I also tried un-hiding it from the GAL and that didn't work.
I did a #Get-DistributionGroup -identity name | fl against the problem group
and another hidden group that does show up and the only difference I see is
there is a value of 2893772 in CustomAttribute13.
I created a new Distribution Group, hid it from the GAL and set
CustomAttribute13 to 2893772 and it shows up just fine.
So I don't see how that could be the problem and don't have any record of what
this could possibly be used for, but I'm unsure about simply removing it.
I hesitate to recreate it only because it causes NDRs if users use the cached
Anyone have any ideas what could be causing this weirdness?
