New Outlook: "Changing the ImapRemoteServerInfo is not allowed" after host migration

Hello Robert,

I'm experiencing what appears to be the same issue described in this thread.

My email address mailto:email address removed for privacy reasons was migrated from Junda to STRATO while keeping the same email address.

I previously used this account in New Outlook. Now, when I try to add it using the correct STRATO IMAP/SMTP settings, I receive:

INVALIDCREDENTIALS TEMPORARILYUNAVAILABLE

STRATO webmail works, and the IMAP/SMTP settings are correct.

The account is no longer listed in New Outlook, so I cannot use the "Remove from all devices" option.

Could you please help escalate a server-side reset of the IMAP provider association / ImapRemoteServerInfo to the Outlook Team?

Before the reset, please let me know what mailbox data might be lost so I can confirm.

Thank you!
