Does the family folder have too much in it.... I believe the folders in OE have a size limitation of 2GB?
Yeah, that's the limit for OE.
Outlook 2007 & 2003:
By default, both versions use Unicode to create their .pst/.ost files and have a limit of 20GB.
Outlook Express, Outlook 2002 and prior versions:
These use ANSI to create their .pst/.ost files and have a limit of 2GB.
