Exchange 2010 Server creating thousands of 1024kb files per hour

For the past week our exchange server has been generating thousands of 1mb log files every hour.  Our backup disaster recovery applicance is processing deltas of 3gb every 4 hours.

I am not an exchange server expert, and  would appreciate any help possible.

The directory is:
R:\MailLogs\MBLOGS01
and the file names look like E010022556C.log

When through all of these steps:

Opened a ticket with Microsoft. worked with them for 14 days.

We have come to the conclusion that 500mb of log files every hour is normal for ~90 users.

These logs that you are seeing are Transaction Logs. They are required. In Exchange 2010 the changed the file size to 1024KB in size so that it would make it easier to ship the logs other DAG members.

You need to check what is running on your Exchange server and also mail flow will increase logs as well. Check the following
- Message Tracking for number of mail items (in and out)
- Changes being make to the database (mailbox moves, deletions, permission changes etc)

The more changes you are making on your Exchange Servers (effecting the databases) the more logs you are going to generate.

I would also be checking any scheduled tasks.

When I run this statement Get-Mailbox | Get-StoreUsageStatistics | sort-object logrecordbytes | select displayname, digestcategory,logrecordcount,logrecordbytes | Export-Csv C:\LogFiles.csv

I need to know what these numbers actually represent (and from what time frame) and I need to know why users are listed more than once.

Any help would be appreciated.

As i stated in my first post the more changes/mail etc that is hitting the database the more logs you generate.

Thanks will, but no one had a "rule of thumb" on how many log files to expect, even the guy from microsoft thought we had a problem, but after 14 days of troubleshooting every part of exchange (we did find many things that could have been causing a lot of log files to generate  (items stuck in poison queue, outboxes, large 48mb file stuck in submission queue, tons of old inactive "active sync" devices that we removed.  Windows HotFixes, Registry entries, Patches...
None of these changed the number of log files to slow down.
