Exchange 2010 extreme mail database

Posted on 2011-10-23
Last Modified: 2012-05-12
So I had just finished our SBS 2011 exchange 2010 setup a few days ago. We use a 1tb drive split into two partitions of 500gb ea. One is used for the OS and Exchange and the other for Data. After setting up exchange I discovered a few days later that Database had gone from about 10gb to over 300gb! I was finally able to get this back down to a reasonable amount by temporarily turn on circular logging and turning it off. This immediatly reduced the size of the database but need to know how to permenatly fix the issue as I am convinced it is goint to build quickly again.

    What were you doing during these days ? moving/importing mailboxes from an old system ?

    What you had is a typical symptoms of new setups when  you need to import or move old mailboxes to it transactional logs will build up quite quickly. That's why it is usually recommended to turn on circular loggin during this time.

    on another had transactional logs will always increase in size and will be flushed once you take a full backup so i propose you introduce a full backup schedule asap

    Akhate makes some excellent points so I would start there, however if it continues here are a few other things that may be of assistance

    If you have users with iPhones or Smart Phones using ActiveSync then one of the quickest ways to see if this is the issue is to have users shot those phones off to see if the problem is resolved.  If it is one or more iPhones then perhaps look at what IOS they are on and get them to update to the latest version or adjust the ActiveSync connection timeout.  NOTE: There was an issue where iPhones caused runaway transactions logs and I believe it was resolved with IOS 4.0.1

    There was also a problem with the MS CRM client awhile back so if you are using that check out this link.

    I would also deploy some tracking methods to see if you can hone in on the culprits, i.e. If you want to see if the problem is coming from an internal Device/Machine you can use one of the following

    MS USER MONITOR: and here is a link on how to use it

    And this is a great article as well

    As you noted above you should also check out ExMon since you can use it to confirm which mailbox is unusually active , and then take the appropriate action.
