It looks like the cause of the problem was Microsoft making "updates" to its IMAP implementation. It appears that they are working on a fix.

Title:
  Thunderbird lost subscribed IMAP folders

Status in thunderbird package in Ubuntu:
  New

Bug description:
  I am an Ubuntu 15.10 and Thunderbird 38.5.1 user. I connect to my employer's Outlook/Office 365 servers via IMAP and SMTP.
  Thunderbird version:  38.5.1+build2-0ubuntu0.15.10.1

  On 20 January 2016, right after receiving a set of updates to some of
  the installed packages, my Thunderbird client lost all the subscribed
  IMAP folders (except Inbox and Deleted). Furthermore, even though I
  can see my folders in the "Subscribe" dialogue window, I cannot seem
  to resubscribe to them by just ticking folders and hitting "OK".
  Nothing happens when I do that. When I check again, no folder is
  subscribed to. I can still receive and send emails, even though I
  cannot copy messages into my Sent folder, which normally used to
  happen automatically.

  As a workaround, unticking "Show only subscribed folders" in Server
  Settings > Advanced shows all folders on the IMAP server (after a
  restart), subscribed or not, which is not quite desirable as many
  unwanted folders pollute the folders list.

  This happened to me on two separate machines running Ubuntu 15.10.

  I cannot immediately spot a connection between the updated packages
  and the problem I described, but I am including the list of the
  updated packaged below in case it helps. There was also a Thunderbird
  update six days ago (14 January), but it has been working fine until
  the updates on 20 January.

  The problem has been experienced by at least one other person (see
  http://ubuntuforums.org/showthread.php?t=2310625).

  Please let me know whether I can provide any further information to
  diagnose the problem. Or, if you have any suggestions for me...

  Thanks,
  Tugkan
