Your Active Backup For Microsoft 365 might be reporting successful backups, but it actually doesn’t backup all Microsoft365 mailbox folders.

Random users are missing random folders since Nov 25th 2024.

Contacting support appears to have solved the problem, you will receive patched, signed file to update manually. After patching I can confirm it pulled hundreds of megabytes of new data and all folders now show up for affected accounts, at least for now.

No info on when will this patch roll out to everyone, or even if it solves the problem completely.

I will update if I get any additional info from support.

holy shit, this is bad! Thanks for the heads up.
I was seriously considering buying Synology to backup mails.

Support confirmed that the patch I’ve received is the same file that will roll out once the official release schedule is ready. No indication on when that is.

I agree. This is bad, more than six weeks of thinking you have backups when you don’t could be catastrophic. I really hope they take this incident very, very seriously and revamp how they test software.
