Also noted here. We are having this issue with our on-prem Exchange 2016.
Here’s the Reddit thread too.
https://www.reddit.com/r/sysadmin/comments/rt91z6/exchange_2019_antimalware_bad_update/
Disabling malware filtering fixed our server. Hopefully we don’t need to keep this disabled for long.
Hello all, yes Exchange 2016 CU22 affected as well. Question, do we understand the level of risk that be involved in disabling the exchange built-in malware filtering (considering we have additional multi-level of other protection in place)?
Or put another way, how effective is Exchange malware filtering? Because if it’s not considered that effective or it’s a nice to have (again assuming you have Spam & other Anti-Virus tools already in place) then the answer is easy.
In our scenario, we’re on holidays and can wait a couple of days. That said, if Monday comes along, we’re damned if Microsoft doesn’t have a fix and the mail needs to be allowed to flow.
Look forward to the feedback.
Take care,

Hello, it appears that Email Stuck in Transport Queues – Microsoft Tech Community discussion and subsequent link to the Reset-ScanEngineVersion.ps1 script has fixed my issue and emails are coming in (the ones in the queue are very slowly coming in, had 534 before 9 AM and now have 515).
Some observations:
Understand that backlogs take time to clear out, just not sure given the above whether I should reboot the server once again, will figure that out by the end of today.
Take care,
IT Manager Geek
Running your own systems is getting more and more a privilege for the bigger companies, with their dedicated IT-staff. Small companies should use the cloud.
Anyway, I’m the admin for a small company too and indeed, I don’t know every nook and cranny. That’s where these forums come in handy 🙂
Our Exchange 2016 server was affected as well. So I ran the script and it threw lotst of errors about removing files. It turned out BITS had a lock on those files. After stopping BITS and performing the manual method, it looked fine again, besides taking the download of new Defender files a looooong time. When that finished, it also took a loooong time for the mail queue to empty….
In the end, all is working well again.
Encourage employees to make their own backups of source or important files to a local device — not cloud. Show them backup techniques using external hard drives. If technology ain’t reliable, employees need to be.
This advice is a two-edged sword.
