The connection to the incoming (IMAP) server was dropped. Please check the incoming (IMAP) server settings and try again.
I’m trying to add a Gmail/Google Workspace account to Outlook with Microsoft 365 Apps, but I keep getting this error during setup:
“The connection to the incoming (IMAP) server was dropped. Please check the incoming (IMAP) server settings and try again.”
What I already checked:
- IMAP enabled in Gmail
- App Password created
- Correct settings:
- imap.gmail.com / Port 993 / SSL
- smtp.gmail.com / Port 587 / STARTTLS
- Internet connectivity working
- Port 993 reachable
- Outlook profile recreated
- Credential Manager cleaned
- Registry OAuth identity cache removed
Google login/authentication succeeds, but Outlook still throws this IMAP dropped connection error.
Has anyone found a proper fix for this issue on Outlook 365?
