  • Exchange 2003, reclaiming white space

    I have Exchange 2003 in SBS 2003. I would like to reclaim white space. Since Exchange is a STD version, can I take the mailstore down, create a new mail database and copy the mailboxes to the new database?

    Thanks,

    You need the Enterprise Edition of Exchange to do that, Standard does not support multiple databases IIRC. So you're looking at an offline defrag sadly.

      How much white space have you got?
      Unless it is at least 35gb with NO prospect of it ever being used again, then I don't consider an offline defrag a good use of time. The database limit of 75gb already takes it in to account.

        Thanks,
        As already said this largely depends on how much space you can reclaim. Do a filter on your event logs for event ID 1221. If there's not a significant amount of room don't bother. Look at getting more storage if possible. After all storage is cheap. And you will require at least 1 and a half times the size of the DB as free space in order to defrag if thats your chosen path.
        Failing that there is a slightly drastic solution that i did for one client recently on SBS which is largely dependent on how much downtime/disruption/outage they can suffer. Which of course in your scenario there is little choice.
        Back up the mailboxes to .pst. Ensure you have a backup of the information store too. Delete the DB. Restart the information store which will create an empty DB/dial tone DB of sorts and reimport the content. Time consuming of course. Will require downtime and is quite drastic and will also affect Outlook to a small degree if clients are using cached Exchange mode. But it will free up some disk space.

          That would also increase the size of the data too as it would lose single instance I would think?

            In my case no. The DB shrunk considerably. But the mailboxes were relatively small.
            Although that is a plausible outcome but is dependant largely on the number and size of the mailboxes. As you know there is no direct link between mailbox size and the size of the DB. Soon as you move a mailbox SIS breaks. So even if SBS did support an additional DB the mailboxes would still suffer some bloat when moved and SIS will always be deprecated to a minor inconvinience
