To override the attachment size limit for OWA public folder posts (default attachment size limit is 1 MB) in Exchange Server 2003:

  1. Open the registry on the computer running Microsoft Exchange and navigate to:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services \MSExchange WEB\OWA

  2. Under OWA, create a new DWORD named Message Size Limit.

  3. Set Message Size Limit to the number of kilobytes you want the maximum attachment size to be. For instance, if you set this value to 2048 (decimal), a maximum message size of 2 MB will be enforced.

  4. Restart the Exchange Server information store.
