Hi everyone; Exchange 2010, SP3, fully patched. The help desk just brought this to my attention, and I have done some testing.
Using the EMC, trying to add/remove members from the distribution list "members" tab. If the distro list contains contacts, the members can take 5 or more minutes to load the OUs - nothing can be done until they are finished loading. If the distro list only contains mailboxes, the tab loads almost immediately. It doesn't matter what OU the contacts are in; whether they're brand new or established. There is nothing in the event viewers; and I can't find anything on the interwebs. Any ideas what else to check? Thanks! Candee
