I would guess from your description, and the lack of support in Thunderbird for Exchange's proprietary protocols, that you have been using IMAP to allow Thunderbird to "see" server-side mail folders.

Do check the subscriptions in Thunderbird (right-click a folder and select Subscribe) to ensure that the missing folders are still selected and subscribed.

In my experience, when Thunderbird updates, some settings can be lost and then may revert to default values. It may have "forgotten" these folders.

The options under Edit|Account Settings|<select account>|Synchronization & Storage may also be of use to you.

Thank you Swarnava. I did try to resubscribe to the folders. They would appear, then disappear within a couple of seconds.

But the issue has now resolved itself, and I'm fully operational again.

Thank you for your response, it is much appreciated.

Microsoft did a Boo Boo and broke everyone's folder list for about a week. It resolved it self when they patched their patch.
