Error forwarding emails with attachments

more options

Hi, One of our clients upgraded from v48 - v92 in Thunderbird due to certificate issues. One of the users is getting the attached image when trying to forward emails. It doesn't happen every time but is happening frequently, every 3-5 sends. When it fails it usually sends the second try. While it does send eventually it is a nuisance. During my testing we sent 3 with no issues then had 3 failures in a row.

Is this a bug and how do we fix?

usual cause ia an anti virus program that is spending to long in it's scanning of the contents of the temp folder.

Try in Safe mode with networking to eliminate than and see if the issue can still be reproduced.

Hi Matt, They don't have an anti-virus program, just using Windows defender. The issue went away for a couple of days and came back yesterday.

Hi Matt, We have 2 users with this update with the same issue, the second one finds it's more of an issue with jpegs for him. Any other suggestions of cause or is it a possible bug?

Thanks
