Thank you for your prompt reply. &nbsp;We have verified the permissions in our Organization Management, and everything is set to what it always has been. &nbsp;What's odd is, just last week we removed a couple of mailboxes, without error. &nbsp;We go and try it yesterday and today, and we are getting this. &nbsp;We restarted the Exchange server last night, as well as the DC's, just FYI.

It took a little digging, but we discovered that the authentication options in ECP virtual directory were not configured correctly. &nbsp;Another tech had confirmed this was altered for &quot;testing&quot;, but was never changed back.

Good Morning,

We are having permissions issues with deleting mailboxes, and also trying to modify our Receive Connectors.  I have attached the error message we are getting.  I have Googled many articles, to verify specific permissions, and they appear to be setup correctly.  Has anyone encountered this before?  Thank you in advance.
