Exchange 2016: No matter what I do, I cannot remove or edit the proxy SMTP address for a Contact. Even if I try to edit or delete it, it pops back in again on reopening the dialogu box, with the format John.Doe@contoso.com (of course, the actual name and domain differs)

Yes, I am logged in with full Exchange administrative rights.

Any ideas or advise, anyone?

Set-MailContact 'currentemailaddress' -EmailAddresses @{Remove=’emailaddresstoberemoved’}
