my company has moved to Google Workspace and our old email provider is no longer operational. I'm trying to move emails within Thunderbird from one imap account to another (same email name). Frequently I get an error message when copying emails in bulk to my Gmail account, "Invalid Argument: unable to parse message". I've done just about every suggestion I've found on the web via searching and looking within the Thunderbird support as well with no luck. Sadly, if I'm bulk moving emails and one of them throws the parse error the whole block fails to transfer. I then have to go through them 1 by 1 looking for the culprit(s). Uggh. Any help is appreciated.
