How do I migrate archives that will result in a PST larger than 2 GB?
The limit on a PST file is dependant on the version of Outlook which is on the machine running the migration application:
Outlook 2000/2002 has a 2GB limit for the PST files
Outlook 2003 has a 20GB limit for the PST files.
When the Notes Migrator for Exchange application reaches the limit depending on what version of Outlook you have installed, will create another PST file.
