Just a note. The "fetch_by_chunks" option indeed works as a workaround. Since there is no option in Thunderbird to reload a single message, you will have to reload the whole folder. To do so, go to the folder Properties and select "Repair Folder".
I believe this is indeed a bug with Exchange (all versions including 2010), but it's good to have this workaround listed here because it looks like MS is not going to ever fix that. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/220991 Title: Thunderbird corrupts attachments from IMAP exchange server -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
