Gmail error: Can not authenticate to IMAP server

(Applies to: ePreserver, Address Magic)

Symptom: You are converting email to Gmail and you get the error, "Can not authenticate to IMAP server: [ALERT] Please log in via your web browser: https://support.google.com/mail/accounts/answer/78754 (Failure)"

Solution:

First, Check that IMAP is turned on for Gmail as described in the link provided in the error message:

https://support.google.com/mail/accounts/answer/78754

Assuming IMAP is turned on, are you using 2 factor authentication?
If yes, you'll need to generate an ASP (application-specific password.) at https://support.google.com/accounts/answer/185833?hl=en as described under, "How to generate an App password".
If no, enable Less Secure Apps at https://myaccount.google.com/lesssecureapps
