Issue
I am trying to set up my UMD email account in Thunderbird, using imap and OAuth2. I receive an error "Unable to log in at server. Probably wrong configuration, username, or password."
Environment
Thunderbird app for reading UMD email
Resolution
IMAP, by default is not enabled for UMD email. In order to read email from Thunderbird, IMAP must be enabled.
- From Google Email (mail.google.com), click Settings and See all settings.
- Click Forwarding and POP/IMAP. Scroll down to IMAP access. Enable IMAP and then click Save Changes.
