Mailbox Size Limit in Exch 2007? RRS feed

  • Question

  • I have a user with a mailbox that just hit 20G. He is getting messages that he has exceeded the limit and can't access or move new messages. We don't have quotas on mailboxes. Is 20G the limit?

  • Yes you've hit the ost limit of 20gb for outlook 2007. The default is 20gb for outlook 2007 but can bump up to 50gb.

  • No there is no hard limit, it's only the limit based on your disk size or the theoretically limit of the database size  16TB. Are you sure there is no quota at the mailbox level or the database level?

    What version of Exchange?

  • I just looked again. There are no limits set for this mailstore. This user is on Exch Enterprise 2007. He runs in cached mode. Is this a limit on the OST file? There is plenty of local disk space.

    This would be our largest mailbox.

  • You are right Patrick.
    There are size limits on OST-files.

  • Thanks. We're bringing the user to Office 2010 now. He should have been already. That should take care of this.
