Outlook 2010 .pst 2GB Limit on File Size

By default, Outlook 2010 does not have a 2 GB limit in file size. However, if your system administrator (particularly if you are part of a large corporate domain) has set a MaxFileSize property in the registry it is possible for a 2 GB limit to be put in place if this has been set. When set, Outlook will not allow the size of a .pst file to grow beyond this size.
