That fixed it for me....the boss finally got an admin assistant and wanted to delegate everything and I've been scouring the Exchange to see what permissions were wrong. oila - took off the Outlook update and it went through just fine as I would have expected it to.... how did you ever find that the update was the problem?? Pure genious. thanks!! ________________________________ From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of Rich Gallo Sent: Wednesday, April 05, 2006 11:48 AM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Outlook 2003 Delegate error Sensitivity: Private Hi everyone, Pulling my hair out on this one (and of course, it is happening to the CFO :-(). When he tries to add a delegate for his contacts and calendar, he is getting a message saying: "The Delegates settings were not saved correctly. Unable to activate send-on-behalf-of list. You do not have sufficient permission to perform this operation on this object." This seems to be happening to only this one user, but I don't really see anything wrong with his permissions in Exchange (2003 by the way)... Any ideas on this? Thanks so much!! Rich
