[AusNOG] On Prem Exchange issues - y2k22 bug.

[Mark Dignam]

People.

 

There appears to a y2k22 bug in Exchange servers - and its fairly nasty. As
of midnight UTC, the Filtering Service stopped passing emails, email goes in
- and never gets delivered to the mailbox.  Easiest thing to look for in the
event logs:

The FIP-FS Filtering Management Service was unable to acquire a scanner
within the specified timeout.

or

The FIP-FS "Microsoft" Scan Engine failed to load. PID: 12348, Error Code:
0x80004005. Error Description: Can't convert "2201010001" to long.

 

Office365 appears NOT affected at this stage. (as expected, with MS's
current "move to our cloud" strategy)

Quick fix for a 2016 system, open a Exchange Management Power Shell screen. 

 

cd $exscripts

.\Disable-AntimalwareScanning.ps1

Restart-Service MSExchangeTRansport

 

And anything waiting in the submission will get delivered in the next few
mins.
