We now have a major problem: users started complaining that one or more of their folders are missing. Initially I thought they might be mistaking or maybe deleted them by accident, but then another user complained and then another. This never happened before, so it`s definitely new. We had no choice but to recover the folders from backups.

Complaints started coming in after 15th of June, so I guess maybe the problem manifested itself after updating to Build 7468 (Jun 12, 2020).

At this point we have no idea how widespread the problem is since people are randomly noticing missing folders when they need them (we get a lot of mail and our users are instructed to keep their mailboxes organized, so it`s customary for us to have 50+ folders and subfolders in our mailboxes).

The biggest problem is that this also affects now our CEO, and after recovering 2 of his folders, he also discovered other 3 missing ones over the week-end. This coupled with the fact that search does not work at all for him (we have an opened ticket for this) and we cannot get MAPI to work in Outlook for us, has left us really upset and disappointed. I`m tasked now with finding alternatives to SmarterMail or just consider MS365. Not sure I can keep confidence in our Mail server much longer in this state, when email is our main communication tool - what we absolutely need for our business to continue.

I`m writing this in the hopes that maybe others have noticed this and we`re not the only ones affected. I just updated our server to Build 7475 (Jun 19, 2020) just in case something changed behind the scenes, but I still need now to ask people to check their folders and see if they`re missing so we can recover them.
