The subfolders and sent folders from two inbox accounts have suddenly disappeared. Bug 1241926
If subcribe to folders is changed, they come back for 5 min and disappear
I have an Outlook account linked to Thunderbird, as well as two Gmail accounts and a Hotmail account. All of my accounts are IMAP accounts. Until yesterday, I have had no problems with Thunderbird. Yesterday the sent folder and the subfolders for the Outlook account disappeared. Today the same thing happened to my Hotmail account. I have followed advice such as subscribe to folders, and I unclicked the "show only subscribed folders" in the Advanced Server Setting. The curious thing is that by doing any of the actions mentioned above, the folders will show up only to disappear again minutes later. I have not done any major Thunderbird updates, nor any other computer work, so this is totally puzzling me.

We do not understand it either. We think it is something on the servers at outlook that they are roiling out machine by machine so only some accounts are so far impacted. But no answers yet.
We are tracking this issue in Bug 1241926 your welcome to follow along as any solution will be reported their first.
It would appear that Microsoft released a bad update to their office365 / outlook.com servers which broke IMAP folders. Microsoft are working on the issue and promise to remediate the situation. For a workaround, please see my blog post. Unfortunately other an that there is nothing more we can offer until Microsoft fix their servers,
