  • Hi Tonycd,

     

    Exchange Server 2003 Standard Edition is limited to a single storage group with a single private information store database and a single public folder database. Prior to SP2, each database was limited to 16 GB of total physical size. SP2 increases the licensed database size limit for Exchange Server 2003 Standard Edition from 16 GB to 75 GB; the default configured database size limit will be 18 GB. Exchange Server 2003 Enterprise Edition storage group and Exchange store options do not change with the application of SP2. However, a configurable Exchange store size limit is added to the Enterprise Edition.

     

    Exchange Server 2003 version

    Licensed limit

    Default configuration limit

    Standard Edition before SP2

    16 GB

    Not applicable

    Standard Edition with SP2

    75 GB

    18 GB

    Enterprise Edition before SP2

    8,000 GB (unlimited)

    Not applicable

    Enterprise Edition with SP2

    8,000 GB (unlimited)

    8,000 GB

     

    So if you add Database Size Limit in Gb registry, the dismount size limit is 75 GB. However, if you don’t add Database Size Limit in Gb registry, the database size limit is 18 GB.

     

    The Database Size Buffering in Percentage setting is a configurable error threshold that will warn you with an event log entry when your database is at or near capacity, and will shut down within 24 hours of the event being logged. By default, Exchange Server 2003 SP2 logs events when the database has grown to within 10 percent of the configured database size limit. This threshold is configurable. The smallest buffer is 1 percent of the configured size limit.

     

    If you database size exceed 75 GB and is dismounted, you can try to upgrade Exchange Server standard edition to Exchange Server enterprise edition.

  • Hi TonyCD

    The size limit on Exchange 2003 SP2 is 75GB.

    <<New functionality has been included with Microsoft Exchange Server 2003 Service Pack 2 (SP2). You can now configure database size limits.

    The database size limits for Microsoft Exchange Server 2003 Standard Edition have been increased from 16 GB to 18 GB. The limit can be increased to as much as 75 GB by using a registry key.

  • Thanks all

    Just wonder what can i do after the database size is over 75gb and dismounted itself. I m now moving forward to enterprise version from standard bcoz the db size is almost hit the limit. But the time is short, Would I just setup the new enterprise version , join the same organization and move the user mailbox one by one first and leave all service such as pop3, smpt, routing, address book, public folder etc to the old server first , and then migrate/remove all services together one week later until all mailboxs moved. Is the plan ok. thanks.
     
    besides, front / back end role installed in one server. Thanks again

  • Hi,

     

    You can install a new Exchange server 2003 Enterprise Edition server into your organization, then migrate mailboxes and public folder to the new server. It is ok.

  • Hi Rock

    thanks. So we have no concern if the users are using pop3, smtp, owa, even "rpc over https" after moved the user mailbox database one by one, the exisitng old exhange server will do find the user mailbox on the new exchange server. Is it ok.

    we have no front-end server. and our firewall has NAT policy that pointed to the old server.

    what about the schedule free information & oab if i have no public. should i transfer/replication before i move mailbox. thanks.

    regards
    Tony

  • Hi Rock

    If some users mailboxes are using pop3 service from outside. Would I only move user mailbox to new server and leave the pop3 service (for the period of time) to the old server and finally the user can connect the mailbox automatially. I just know outlook (mapi) can but not sure for pop3. Thanks again

    Regards
