Zimbra external account Gmail
"Error: Invalid credentials", while adding Gmail as an External account
Problem
Error: Invalid credentials, while adding Gmail account as an external account (POP3/IMAP) in Zimbra.
Solution
By default google will not allow to configure Gmail in other applications so, less secure apps should be allowed in Gmail.
Once less secure apps allowed, POP/IMAP should be enabled in Gmail to configure Gmail account in Zimbra.
Note: Zimbra, configured external account takes storage from users assigned quota.
Step-1: Allow less secure apps in Gmail
- Login Gmail account --> click on profile image --> Manage your google account --> Security --> Less secure apps --> Turn on access
- Make sure POP3/IMAP enabled in Gmail
- To enable POP3
- Login Gmail account --> Settings (Gear icon on top right) --> See all settings --> Forwarding and POP/IMAP --> enable POP for all mail / Enable POP for mail that arrives from now on
- To enable IMAP
- Login Gmail account --> Settings (Gear icon on top right) --> See all settings --> Forwarding and POP/IMAP --> enable IMAP
