should not be used with mailboxes over 50GB

Although mailboxes of 100Gb or more are available ( Plan 1 – 50GB, Hosted Exchange plan 2 – 100GB), it is advisable to upgrade to the latest version of Outlook ( 365 or Office ) if your mailbox size exceeds 50GB

By default, Personal Folders (.pst) and offline Outlook Data File (.ost) are in Unicode format in Outlook 2010 and Outlook 2013. The overall size of .pst and .ost files has a preconfigured limit of 50 GB.

This limit is larger than the limit for Unicode .pst and .ost files in Outlook 2007 and Outlook 2003. The new Outlook file size limit of 50 GB can be increased or decreased by making changes to the Windows registry.
