User receives an error very similar to this error http://support.microsoft.com/kb/950794 when trying to add a delegate. I tried to add the delegate to the users mailbox through EMC and receive Set-Mailbox Error: Couldnt find object xxxx/xxxx/xxxx Please make sure that it was spelled correctly or specify a different object. Reason: The recipient xxxxx/xxxx/xxx/xx osmt the expected type. This error is referring to a inactive user object? I get the same error even I try to add my account?

Can you run get-mailbox youraccount |FL isresource is it set to false? Also run set-mailbox youraccount -applymandatoryproperties than try setting your account as a delegate again.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

I forgot to mention that we are in a EX2010 environment. All mailboxes are false, they are not a resource.Jason

Did you try running the applymandatoryproperties on your account to test?James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com
