Hi Lyubo,
Yes, I'm currently still taking Private Messages for this topic to escalate the mailboxes to the Outlook Team for a reset.

Hi Robert,
I am experiencing the same New Outlook IMAP migration issue.
We migrated our email hosting from SmartServers to DreamIT, but New Outlook keeps restoring the old IMAP server configuration.
I have already tried repairing the accounts, removing them from all devices, and testing in a fresh Windows user profile. Nothing has worked.
Newly configured accounts connect successfully to DreamIT, while previously configured accounts continue using SmartServers.
Could you please help escalate a server-side reset of the old IMAP configuration?
I can provide the affected email addresses privately.
Thank you,
Tuan
