Exchange 2010 - trnres00001.jrs and trnres00002.jrs Not Logging
It may my misinterpretation of how these files work. We had an issue where the C: drive fell below 4 GB of free space and the queue started rejecting external email. Obviously we shouldn't let the drive get that low on space, but someone overlooked the alert and it happened. In the future I will be running a scheduled script to clear out old IIS logs which will keep the drive in check.
But what I am trying to figure out is why email that wasn't being delivered, didn't end up being logged? Again, I may just be misinterpreting how it works. This is what I read.
"Reserve log files (Trnres00001.jrs, Trnres00002.jrs,...) Files that are used to reserve space for additional log files if the current log file becomes full."
I read a few other things, but what I was thinking it meant that if you fell below 4 GB of capacity, email will still be logged to those files and eventually be delivered once there is enough free space. That didn't happen. No email was logged. Also, nobody ever received a NDR saying their message wasn't delivered. So during the time frame that there was only about 3 GB of free space, no external email messages came through and nobody sending the messages knows their email was delivered. This obviously doesn't make management happy.
So how exactly is it supposed to work? I am guessing those log files are only used when the mailbox database logs no longer have capacity and not when the queue DB doesn't have enough space.

Normal = 92%
Medium = 94%
High = 96%
The actual capacity of the disk is 49.9 GB.
At 6:05:25 PM yesterday there was Event ID 15004 saying the resource pressure increased from Normal to Medium and also states the following components are disabled due to back pressure and mentions Inbound mail submission from the Internet. So resource pressure is medium, but back pressure is disabling mail submission? The used capacity at that point was 46.88 GB which would be 93.9%. At the exact same time I received event ID 15006 saying the Microsoft Exchange Transport is rejecting message submissions because of the available disk space.
The used capacity of 46.88 GB was the same for at least 5 hours prior without any issues or warnings. It wasn't until 6:12 PM that it increase to 46.95 GB (94%) used.
You said.
"When your server gets below 4GB of space your exchange server will no longer accept inbound mail to the mail store. Instead it will save the mail into a queue folder."
But this is what I am asking. I had no messages saved in the queue folder. Exchange and the queue folder are both on the C: drive. With 3 GB of free capacity, how come nothing was saved in the queue folder? And does it stop accepting inbound messages because the drive where Exchange is installed falls below 4 GB, or is it based on where the queue database is located?
