What type of account are you using when you attempt this operation? Is the account a member of Exchange Organization admins or at least Recipient admins? (or appropriate RBAC management role group).Please mark as helpful if you find my contribution useful or as an answer if it does answer your question.

Hi, I appears you have multiple recipient policies created with different filters. I'd suggest you remove the other polices created and let the default policy apply. Hope it is helpful.

check permission of 'C:\Program Files\Microsoft\Exchange Server\V14\Mailbox\address\SMTP\AMD64\inproxy.dll' confirm if System and Administrators have full permissions

As Sandeep said check the permission and also make sure the folder name 'Address' under ''C:\Program Files\Microsoft\Exchange Server\V14\Mailbox' is shared with following shared permission MBXSERVER\Administrator - Full control Mailbox server object - Full control Security permission Authenticated users - Read System - Full control Administrator - Full Control on Inproxy.dll make sure permission is getting inherited from parent folders Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
