The account in question uses ExQuilla to connect with work Exchange server. A couple of days ago I lost connectivity (got no new messages) so I delete and remade the account using the same name. I did not notice until today that the account was now duplicated ONLY in the left panel of the Account Settings dialog. They are not separate accounts with the same name: editing the name of one renames the other identically. Every action I've tried in the left panel (accounts listing) begets "An account with this name already exists. Please enter a different account name." (t\The pop-up typically appears twice.) I'm getting new mail, but I cannot assign a smtp server to the (semi-)new account due to the above. I can re-assign the smtp server per email but not set it permanently and frequently forget and this is causing confusion. Is there any remedy for this?
