The Microsoft limit for PST's is now 16GB - please expand your product line to allow for the increased PST size during exports from the DA product.

DA 10.x  guide states :

The maximum size that CA or DA will export is 1.5 GB when using a supported version of Outlook on the CA or DA server" on page 155.

The current permissable PST file sizes can be found here:

Creating multiple PST files for an export is problematic from a tracking and maintenance point of view.

Thanks,
