I am experiencing a persistent issue with Mozilla Thunderbird, which continually prompts me for my Gmail login credentials. This account was previously hosted on Gmail (Google Workspace), but I migrated my email to Zimbra. Despite this transition, Thunderbird keeps trying to connect to the old Gmail account, leading to repeated login requests.

I would appreciate any guidance on how to resolve this issue and ensure that Thunderbird recognizes the new Zimbra setup without attempting to access the old Gmail account. Thank you!
