Exchange 2003 logs increase dramatically in size
I've had some interesting interactions from 2 seperate sources - one from Facebook and one through email talking ab out the same customer.
Jonathan originally contacted me through facebook talking about an Exchange 2003 server where the log files were growing like crazy from an Outlook 2007 client and totally filling up the server. We chatted about it, and I suspected this was an OST file issue. Jonathan searched for the rogue file and deleted it which seemed to sort this issue
The symptoms:
Exchange logs for a given storage group increase dramatically. In this case 100Mb per Minute. A client is sat trying to update folders, but never can. The client is Outlook 2007. We escalated this to the Support centre.
We know what the fix is for this problem. The OST file seems to be the issue, so turning off cached mode fixes it. Also building a new OST seems to work. Either way the issue is down to one Outlook 2007 client causing the issue. We have now seen this on two separate sites with identical symptoms.
For this reason we (in fact the customer, asked as he wanted to see some information in the wild about this) wondered if you would mind asking Eileen to blog about this on her site. At least that way there will be a chance for customers to know what the issue is and find the rogue Outlook 2007 machines before the stores shut down. NB: in this case the customer ran continues online backups to ensure the logs were committed and deleted, but equally circular logging could have helped. Also note that to find the client, you can eliminate OWA, Outlook < 2007, etc, the problems seems to be with Outlook 2007 in cached mode.
I've searched through the knowledge base, and I can't find any kb article or document outlining the problem, so I've blogged it as requested.
So perhaps if your Exchange server log files suddenly start to fill up really quickly and unexpectedly, then perhaps this may help you pinpoint the problem and get your system working effectively again...
