Subject: Request to reset New Outlook IMAP server association

 

Hello Robert,

 

I migrated my custom-domain email account from OVH to Comvive. The email address remains the same, but the IMAP/SMTP server has changed.

 

New Outlook for Windows accepts the new server settings but fails to connect. I have already tried removing and re-adding the account, resetting and reinstalling Outlook, and the other troubleshooting steps, without success.

 

I also contacted Microsoft Support more than a month ago and have received no response.

 

Could you please help me request a server-side reset of the stale IMAP server association (ImapRemoteServerInfo) for my affected email address?

 

I understand that this reset may delete cloud-only data, including drafts, contacts, calendars, tasks and notes that are not synchronized with my mail provider.

 

Thank you.
