  • Exchange Store 'Over Limit'

    Dear All,

    Over the past few days I have been getting the following Event Log error message which either stops my IS or Mounts the Exchange Database offline.

    - Exchange store 'First Storage Group\Mailbox Store (XXXXX)': The logical size of this database (the logical size equals the physical size of the .edb file and the .stm file minus the logical free space in each) is 76 GB. This database size has exceeded the size limit of 75 GB. -

    I appreciate the message is quite self-explanatory (indeed one of the more helpful Microsoft messages) yet I can restart the IS/Mount the DB without taking any further action.

    I am unable to see how I have reached the 75GB limit.

    My current edb+stm file shows on the drive as 92GB yet clearly this contains some white space. When I export the mailboxes to excel the total is only 61GB. It was only a couple of weeks that my edb+stm totalled over 130GB and I did not have any issues. I recently ran a defrag to reduce this but this error message has happened post this.

    Am I missing something in my calculations?

    I am using Exchange 2003 Standard Edition.

    Thanks

    Jim

    If you have an online maintenance schedule filter for event ID 1221 in the logs. This will tell you how much white space is available that can be reclaimed. Additionally do you have limits set on the size of mailbox's? If not now is the time to start unless you want to upgrade to Enterprise. Note adding up the size of mailbox's will not give you an accurate representation of your mailbox database.

      Hi Scurlaruntings,

      Thanks for your reply. The logs say that I have 12GB of white space free. If I assume I minus this figure from my edb+stm which currently totals 92GB this would mean I am running at 80GB which would surely have dismounted the stores by now and would not be able to use Exchange at all.

      However my mailboxes total 62GB when I export them into Excel as previously mentioned. I am still confused as to the correct figure.

      As for mailbox limits they are at 300MB but recently we have taken on 5 new people who have mailboxes between 4-6GB. It is political to try to have these reduced and we do not have a sufficient archiving solution in place.

      Thanks

      Jim

        Use the eseutil switches to do an offline defrag to reclaim the space. This will require downtime though. Additionally check what your retention is set to. The default is 7 days. You may be able to reclaim some more space there.

        As i have already said dont bother to add up the size of mailbox's to correlate that with the exchange database as they are not logical. Long term though your options are to either upgrade to enterprise, get a archiving solution like GFI or EV or get those larger mailbox's down to an acceptable limit. What you are encountering are the natural limitations of Exchange Std Edition.

          Hi Scurlaruntings.

          Thanks again for the quick response. I appreciate that these are the limits of Exchange Std and believe me I am trying to get investment in an Archiving solution or an upgrade to Exchange Enterprise but I don't pay the bills

          I guess there is no points in me trying to calculate the exact size of the DB, if it says it is over then I guess it is. I am still a little confused as to how I can still run if I hit the 75Gb limit?

          As for the Offline Defrag that is not an issue, it was only three weeks ago that I ran one and weekends are generally quiet. I guess this alone wouldn't solve the issue as the error message states that it is the amount of data minus the white space so reducing the white space alone will still not really help.

          However, I am blitzing the large mailboxes on Monday so I will have some more time to decide a solution.

          Thanks again

          Jim

            Adding the total of the mailboxes up is never going to equal the size of the store.

            "When you view the space that a mailbox uses in Exchange System Manager, the amount only includes the space that is used by the Priv.edb file. The amount does not include the space that the Priv.stm file uses."
            http://support.microsoft.com/kb/828070/

            Doing an offline defrag is also a waste of time, because all you will get back is the white space (plus perhaps at most a little more). Furthermore it is not risk free and will result in data loss.

            You basically have two options.
            1. Upgrade to Exchange 2007 or 2010, both of which support unlimited (well 8TB) database sizes in the standard edition.
            2. Invest in an archiving solution.
            Using PST files to extract email is NOT an archiving solution. If you value the email then you don't store it in a PST file.
            3. Ask the users to delete the junk from their mailboxes.

            You cannot purchase Exchange 2003 any longer, so to purchase Enterprise edition you would have to purchase Enterprise edition of Exchange 2010 and use downgrade rights. You may as well purchase standard edition and the required hardware to run 64 bit.

            Simon.

              Hi Sembee,

              Thanks for replying.

              Personally I hate PST's but I have been trying to get in an archiving solution for most of the two years I have been here but I am dealing with an individual who just doesn't get it.

              However needs must and with no investment (including an upgrade) I have to use best fit!

              Thanks

              Jim

                I hope that you aren't in an industry where you need to retain the email for a period of time by law, because depending on PST files to fulfil that requirement will almost certainly fail.
