I facing issue that my Thunderbird failed sync exchange email to my Thunderbird mail client.I’m getting the following error:-
The RETR command did not succeed. Error retrieving a message. Mail server mailserver.com.my responded: Message corrupted
From the above error already indicates an error on the server and not in Thunderbird. There is a corrupted email in email inbox.
To solve this issue, first you have to logon to webmail and check all the email to find out any abnormal email and remove it. If you not sure which email is corrupted email, you just empty you webmail inbox. Once done, you try to re-sync or re-download email from your Thunderbird.
