I need to gain access to an Outlook PST file that grew over 2gb [duplicate]

Solution 1:

Don't know about that tool, but here is a tool provided by Microsoft to deal with that issue - Oversized PST and OST crop tool. You may want to make a copy of the PST before you attempt a repair.

NOTE: Use the tool to create a truncated copy of the .pst file. The copy that is left after the tool completes does not have all the original data because the tool cuts a user defined amount of data from the file.
