Our latest event “IT-Pro Chalk Talk” co-hosted with Winsec & IT-Talks was very interactive and several questions arose during that session.
This is the first question that I will summarize what we all talked about.
Question : Exchange Backpressure keeps kicking in because of diskspace issues and we don’t really know where to look for
Background : If Exchange Backpressure kicks in then All message flow stops, and the server rejects all new connections and messages. (Hub Transport server)

Monitor the disk usage on the Exchange Server if possible :
- Use Performance monitor
- System Center Operations Manager
- Other tools …
- Use alerting to inform disk space usage
If diskspace is already low and you want to find out what folders are very big:
- Disable backpressure as a last resort
- Use mount points to use other storage/disks
