As title says. about 1/5 times, the message (e-mail) is just gone. Nowhere to be found. Not in Deleted folder. Only way I can access this e-mail is logging into hotmail.com (because I have a hotmail account), then I find it in the junk folder. So it’s not gone from the server, just gone in Thunderbird.

Restarting Thunderbird has no effect.

Has anyone the same experience? Should I submit this as a bug?
