is there a limit to the number of .pst files I can have open in Outlook 2007?

I have a user with huge personal folders and I want to split them up into smaller ones.  Is it a problem if I set here Outlook to open 7 or 8 .pst files at once?

There is no limit for the number of pst you can have in one outlook profile
If you add too many PST in one profile you might face performance issue with outlook
Also make sure that PST file is below 2 gb(as recemmonded by microsoft)

Previous versions of Outlook had a 128 file maximum but I have not been able to find anything posted for this issue on Microsoft's site (and I've searched for this many times).  

Also, Microsoft Office Outlook 2007 and Microsoft Office Outlook 2003 have both a different format and a larger overall size limit for the personal folders (.pst) file than the .pst files that are in the earlier versions of Microsoft Outlook.  In Outlook 2002 and earlier, the .pst files are in the American National Standards Institute (ANSI) format, and the overall size has a limit of 2 gigabytes (GB).  By default, .pst files are in the Unicode format in Outlook 2007 and in Outlook 2003. By default, the limit for a Unicode .pst file in Outlook 2007 and in Outlook 2003 is configured to be 20 GB.

If you are using a PST that was originally created in Outlook 2002 or earlier, you will need to convert your data from the older .pst file format to the newer format to provide you access to the Unicode character sets and larger file size capacities.
