'#' is a special character in LDAP and in PowerShell. So it has be escaped. (And in C and C++ for that matter. I don't think it is in C#, somewhat ironically.)
What tool did you use to change the name? Any object has a bunch of name-related attributes associated with it. 'name', 'displayName', 'simpleDisplayName', 'CN=another-name', etc. If it's an Exchange object and you changed it with ADUC I’m not surprised it 'disappeared'. Change it back with ADUC and then rename it with EMS or EMC. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Kurt Buff Sent: Saturday, June 18, 2016 5:17 PM To: [email protected] Subject: [Exchange] A very strange problem with a DL - Exchange 2010 Someone recently created a DL with a '#' in the name and alias (it's for our C# programmers). It displayed fine, but when using PS to manipulate the group, it showed up with '\#' - which was interesting. I wasn't happy with the name used (it didn't match our naming standard) so I changed the name to use 'CSharp' instead, as well as to match our naming standard. Now I can't find the group in Exchange - at all. Not in the GAL via Outlook, not in the EMC, and not with get-distributiongroup, even more than 24 hours later. I haven't rebooted the box yet - I'll probably do that tomorrow morning. I can see the group with get-adgroup, but that doesn't expose many of the properties, including 'Alias', which I believe still has '#' in the name, and which I suspect is causing the problem, though I don't know for sure. I could just delete the group through AD and recreate it, but that seems like a less than optimal approach. It's quite baffling, and I'd love a clue as to how I can proceed. Kurt
