New Outlook: "Changing the ImapRemoteServerInfo is not allowed" after host migration
Hi everyone! I've migrated my domain/mailbox from one IMAP host to another in May. It cannot be added to New Outlook for Windows — fails instantly with INVALID_CREDENTIALS INTERACTION_REQUIRED, even...
Hi Robert, I have exactly the same issue. My mailbox email address removed for privacy reasons was migrated from IONOS to CDMON, keeping the same email address. New Outlook still retrieves the old IONOS servers and returns INVALIDCREDENTIALS EXTENDEDERROR. The mailbox works correctly in Classic Outlook, SOGo and on a new device. The account is no longer present in New Outlook, so I cannot use “Remove from all devices”. Could you please escalate my address to the Outlook Team for a server-side reset of the IMAP provider association / ImapRemoteServerInfo cache?
