  • Mailbox Sizes

    Good morning everyone,

    I hope everyone is having better weather than I am.

    I have a question regarding mailbox sizes. I am using Intermedia as a Microsoft Hosted Exchange provider. I am using Microsoft Outlook 2007 as our email clients. What is Microsoft's recommended mailbox size? Some of our email boxes are close to 3GB and they run slow. IS there a whitepaper out there that I can refer to?

    Any help is much appreciated.

    Ragards,
    Tommy

      Mailbox performance problems are usually related to the number of items per folder rather than the mailbox size, unless you're connecting via POP and you have a large pst file. How are your Outlook clients connecting the the Exchange server, via POP or RPC over HTTPS?

        3GB is peanuts.
        As already pointed out, the performance issues are number of items. You should be looking to keep the number of items in any specific folder to less than 5,000 items. That may mean lots of sub folders.

        Microsoft do not make any recommendations on the size of mailboxes - as it is what that business needs and can afford. With Exchange 2007 having effectively unlimited storage, the only limit is on what the server can take and the backup/recovery time.
