TB seems to be having trouble communicating with outlook. My email is *******@msn.com. I also have 2 other accounts setup in TB at Yahoo & Gmail that work fine. Several times I have opened TB and all folders (inbox, sent, junk etc.) are missing from my msn account. It just shows the account name and there is no arrow to drop down or hide the folders. Looking in the AppData for TB I see that in the folder imap-mail.outlook.com. Many files are missing or changed compared to the folders I have backed up. I replace the files from the back up and things may be fine for awhile but it does not stay that way. This has happened more often in recent days and I decided to uninstall TB and I deleted the AppData and started fresh. But TB is still having trouble communicating with outlook.com. It starts downloading folders then times out or gives other messages and now again my MSN folders have deleted. I'm getting sick of messing with this but I'm ready to try any suggestions you kind folks may have to offer. Also Just tried safe mode and its the same problems. When I set up the MSN account I use the automatically configure option.

@Wayne Mery, Thanks for your suggestion. This problem stated months ago when I was using version 38.2.0 and maybe as far back as 38.1.0. It is just happening a lot more often now.

@sfhowes, thanks for sharing that link. It does seem to be the same issue I am having. I will follow it and see how it develops.

Hi there,


I've been having problems with Hotmail for Thunderbird for the last many months. I have added, re added accounts, checked many times. First off its very slow to sync, extremely, takes days, hours, the connection times out a lot, tried decreasing the tcp connections, no go. Looked online a lot. nothing.

Secondly, when collapsing the hotmail account, all the emails disappear and has to resync. Same thing happens when opening thunderbird at random, tired of it I started using hotmail in windows live mail.

Any fix for this please? Use auto settings and manual, Imap. imap-mail.outlook.com 993 SSL TLS

This problem was new to me in early October, around version 41 for TB. While I do not know yet if my fix is permanent, it appears to be so far. I would recommend AGAINST doing a lot of heroic/time consuming efforts that, at least for me, were not helpful (reinstalling, old versions, etc.). The best I can currently suggest is just to BE PATIENT (as patient as one can be at least), and walk away and let it reload all your old folders, mail, etc., and then come back and manually inspect them to ensure it is complete. It makes no sense that it can affect the local cache, so I don't know if it truly is reloading what used to be in the cache and is now somehow gone or if it no longer recognizes the old cache and needs to act like it is downloading the folder tree again, etc for the first time. In my experience if you only partially allow the redownload it does not work, but after I did this once exhaustively, physically opening up every folder and ensuring that EVERY folder repopulates, it has stayed fine for the past 48 hours. Some subfolders do not repopulate unless you physically open them up.
