Account will not connect
Fix common OAuth and SMTP/IMAP connection failures.
Overview
Connection failures usually come from provider permissions, wrong credentials, disabled protocols, or admin restrictions.
Recommended workflow
1
Confirm you are signing into the intended mailbox.
2
Check provider admin permissions.
3
For SMTP/IMAP, confirm host, port, username, and app password.
4
Try reconnecting in a clean browser session.
5
Contact support with the provider and error message if it still fails.
Tips that make this work better
Tip
OAuth approval may require an admin.
Tip
SMTP auth may be disabled by Microsoft tenants.
Tip
App passwords often require two-factor authentication first.
Common mistakes to avoid
- Retrying the same wrong password repeatedly.
- Connecting an alias instead of the mailbox.
Done well, this should leave you with
A cleaner Outlio setup, fewer avoidable campaign issues, and a more reliable path from setup to replies.
