Mailscavator

Important for 64-bit Outlook users:  Mailscavator is natively 32 bit and will crash.  However, a 64-bit updater is included to fix this - see Readme after downloading.

Have your .PST (Outlook archives) files taken over? MailScavator lets you select all your PST files and re-organize them by date and size. So you will end up with files named "Jsmith 2007.pst" etc.

Go Industrial on your PST Files!

This first tab is also a good Outlook Profile PST manager.
You can add multiple pst's at once using shift-select. You can remove PSTs.

Split by date options are Year, Quarter, Month
Split by size will create part1, part2 type files.

The filtering is powerful. Use this if you only want a subset of your mail to be MailScavated.

The default operation is Move (to move messages to the new PST files) but you can also do a Copy or just a Scan (useful if all you want are the stats).

Addresses / Days Stats

If you want MailScavator to collect stats about all the addresses it finds, put a check in the 'Addresses' box. It will display all the unique addresses and days.

When the scan is done, the program logs results into XML files so you can open them in Excel.

More Information about .pst files

Outlook uses .pst files to store all of it's data. Each root-level 'mailbox' on the left side of outlook represents a single .pst file. Right-click -> Properties will show you the location of the .pst file.
