Multiple PST Archives / Merging - Best Practices

Hi,

I've got

1.1Gb
1.2Gb
3.5Gb
2.3Gb
and
14Gb

Outlook archives.

Just the 14Gb is visible in the right pane of Outlook, under the active day-to-day folders.  Does that mean the other archives are not searched?

Seems like, if I wanted to have ALL the data available, I should merge them?  Am I right?

If yes, that'd be over 20Gb in one .PST  What's best practices here?  If it were you, and you wanted access to the messages, would you merge them all into one huge PST?  And then keep that open along with the main data file in Outlooks right pane?

Or, is there a better way to be sure I'm searching all my mail?

Sincerely,

OT

You have to have a PST file added to a profile in Outlook for it to be searched, so you can either merge the files or add them all to the profile. Merging is an acceptable option, since Outlook PST files don't suffer from the extreme limits they used to. Performance will be better with one file than with 5, but you probably wouldn't notice too much of a difference unless they're all on a really slow hard drive. Outlook startup speed would be much slower with 5 than with 1, so merge is your best option here. Just note that it will take a long time for the Windows Indexing service to crawl through the whole file (Again, longer with 5 files than with 1)

As for a better way to handle mail searches, having the email on an Exchange server, either in a normal mailbox or an archive mailbox, would allow the Exchange search index to handle things.
