Our Exchange server has started to act up in the past week.
We have a FE server with 2 BE servers. One of the BE ones is located in NY while the FE and the other BE are in London.
As of Friday last week, the BE in NY starts to queue up on local delivery service and simultaneously, the owa grinds to a halt.
A reboot resolves all of this for a few minutes before it all happens again. The London FE and BE are unaffected.
Can't find "any" errors in Event Viewer, so I'm a bit stumped as to where to begin troubleshooting.
