Outlook file size limits
During our radio show we had discussed Microsoft Outlook, and the subject of size limitations was mentioned...
Per the article, "The .pst file has a different format and folder size limit in Outlook 2007 and in Outlook 2003":
The .pst files for IMAP or HTTP accounts in Outlook 2003 are limited to 2 GB.
In Outlook 2007 and Outlook 2003, the Internet Message Access Protocol Version 4rev1 (IMAP4) accounts and HTTP accounts are configured by default in the Unicode format...making their limit to be 20 GB.
