This probably isn’t much help, but if you run Get-mailbox username | fl grantsendonbehalfto
Does it show anything in the field there? If so, you might be able to clear it with set-mailbox. If nothing there, run Get-mailbox username | fl * and look over all attributes for anything amiss compared to a working account. One other thought is that delegates usually modify permissions on the calendar and tasks, so maybe checking base permissions in those two locations of her mailbox and that they haven’t been changed? -Bonnie From: listsad...@lists.myitforum.com [mailto:listsad...@lists.myitforum.com] On Behalf Of Kurt Buff Sent: Tuesday, December 22, 2015 1:26 PM To: excha...@lists.myitforum.com Subject: Re: [Exchange] Exchange 2010, Outlook 2013 - cannot remove delegates Lost my join.me<http://join.me> session, so can't do anything with her client directly ATM, but would still like to hear what I might have missed.

She wishes to get rid of all of her delegates. The exact error message is: "The Delegates settings were not saved correctly. Cannot activate send-on-behalf-of list. Operation failed." I tried 'set-aduser username -clear publicdelegates', but that hasn't had an effect. On the account I've granted SELF "Write personal Information" - "Write Exchange Personal Information" was already granted. I've used adsiedit to examine her publicDelegates attribute, and it's empty. She's in our UK office, and gone for the day - I'm connected via join.me<http://join.me> for the moment. Any thoughts on how I might fix this? Kurt
