Running Exchange 2010 SP1. At random about a week ago, we've been unable to add any new Outlook profiles. When we do, we get the error listed in the title: The action cannot be completed. the name cannot be matched to a name in the address list.
After hours of searching, all the 'usual suspects' are turning up empty (typically showinaddressbook attribute, check/uncheck 'hide from GAL', etc...). I'm just flat out of ideas here - this issue is across the board (all accounts) rather than just one or two. Please help! Even some suggestions on where to look or how to debug this would be something!
