Thunderbird-Hilfeforum

Immediately after upgrading to Thunderbird 102.0 several of my new and existing emails began showing code in the email body (and the usual button controls are missing - Reply, Forward, Archive, etc). On one email this morning the body of the email has a few lines of code followed by the body/text from an email several months ago Running Windows 10 on a desktop PC. Also run Malwarebytes PrivacyVPN and AVG. I searched web and saw how you can "repair" a folder/email. However, when I selected/clicked on Repair it appears nothing initiated. I also saw a post to rebuild the folder by deleting the .msf files - but I could only find for send or draft and only for a couple of my (15) emails. Meanwhile on my SurfacePro 7 running Win11 and Thunderbird 91.10 emails appear correctly (that are corrupted on my desktop; including this morning's email that showed the body of another/previous email - displayed correctly on my SP7) I would appreciate any help/direction you can provide. Thank you, Mike
