I have an issue where during any 12 hour period (Mon-Fri) one of our database with about 700 Mailboxes generates an astounding 75GB of log files (in 12 hours). We contacted Microsoft and got some pointers but unfortunately the issue wasn't resolved. Skipping forward several months...
I now believe that I have nailed the issue down to the following:
1) Users are sending attachments that range in sizes from 5MB to 50MB
2) Users are sending to 10 or more recipients
My question is simple (and I think I know the answer) I just want to confirm it:
Message Size (Total Bytes) + Recipient Count = Actual amount of data that has been generated by exchange for the email that was sent?
Here is an example: (From out log files)
user1, user2, user3, user4, user5 @ ourdomain.com
Recipient Count 10
Does that mean that the actual amount of log files generated is Total Bytes x Recipient count? = in this case 60MB for a 6MB attachment. ?
