  • Exchange 2003 Database is over 75GB

    Hi all,

    My Exchange 2003 database is above 75gb in size (80gb to be exact) and constantly dismounts, Were running Exchange 2003 standard so I'm unable to create a second mailbox store.

    What is the best solution for this?

    Many thanks in advance.

    1. run an onffline defrag. This will need your mailbox to be offline for probably close to 48 hours - may nmot necessarily get you alot of space back
    2. delete any old mailboxes, then repeat 1.
    3. enforce a mailbox size limitations. Prevent users from sending and receiving if their mailbox is over the size limit.
    3a. enforce archival rules on end users, make them archive once their mailbox hits the hard limit.
    3b. create a policy that deletes items from deleted items folder and junk mail folders that are older than 14 days. Then repeat 1.

    4. upgrade to EX2007/2010. (not to be taken lightly)

      An offline defrag is a waste of time as the database restriction already takes in to account the white space. An offline defrag will gain you a small amount of space.

      Realistically, your only option is either a move to an archiving product or to Exchange 2007/2010. Anything else is a band aid to a seven year old product.

      I don't consider archiving through Outlook to be a valid step as that removes content from Exchange in to PST files. If you value the data you don't store it in PST files. Almost impossible to backup (as accessing them over the network is not supported), they are bloated and regular fail.

          Rob -

          I would first look at the usage for each mailbox in your organization. You might find the issue is a single user (I have one user who likes to keep all of their Deleted FOREVER, since he is the owner he can do it..) or it might be more systemic (all users over 2gb, etc).

          I believe adding a second store will not help you, as the total cannot be more than 75Gig.
          --------------

          Simon -

          Do you recommend any particular archiving solution?

          I have been considering GFI MailArchiver as it is much cheaper than buying exchange 2010 and upgrading all my licenses and I believe I can continue to use it with 2010. (Perhaps Exchange 2010 has this built in?)

          I was also looking at the EMC solution called OneSource, but it is brutually expensive for a small user base (I have only 100 users).

          Thanks,
          Hobie

            Exchange 2010 does have built in archiving, but it is little more than a glorified front end to PST files. Not worth considering IMO.

            GFI MailArchiver isn't bad at all for the price, it uses a SQL back end though so make sure you've got space for that on the server. Given how cheap disk space is now I only really recommend archiving when there are legal requirements in place regarding retention, E.g Financial Services and such like. We use Symantec Enterprise Vault for archiving, but it is not a small business solution.

              That is wrong.
              Have you looked at the archiving solution that is provided with Exchange 2010? It doesn't sound like you have.

              It uses a second database and effectively a second mailbox. The content is moved from one to the other. It doesn't use PST files, never has done.

                You're right, in that I was given that information pre-RTM and took it at face value. I've never re-investigated it as we use EV and have no intention of changing for obvious reasons.

                That'll teach me to listen to our MS re-seller.

                  Pre RTM information changes, and in fact there were pretty significant changes between RTM and SP1 with regards to the archiving feature. Then you get resellers who have a vested interest in selling something else, or simply tell lies to customers, and it gets out of hand.

                  No harm done, I caught it early enough so that it didn't become another FUD around Exchange.
