Outlook is slow when searching

The scenario is the user has a desktop at home with outlook 2007. The .ost file is 8.16 gb. I have advised the user that outlook will be slow/sluggish when the .ost file is that big. Any help/suggestions are welcome.

Thanks in advance.

    The search speed is somewhat dependent on the OS indexing ability.  If the desktop is Windows Vista or 7, then the indexing is on by default.  If it is XP, then the addon Windows Search 4.0 is needed.

    In any case, just as you said, a OST file of 8.16 GB is very detrimental to Outlook performance.  Outlook OSTs and PSTs are not meant to go over 2 GB and the user is already 4 times over that.  Even with the indexing ability, a OST file that large will yield sluggish results.

    They will have to delete or archive at least 80% of the email and then clean/compact the OST file to regain near normal performance.  I'd say start with the emails with very large attachments.

    i agree and have comminucated this to the user in many of our previous emails. I am unsure how to properly communicate this to the user in a way that can move forward with an archiving solution. Thanks for the response

    I wish I could help on communicating it to the user convincingly but I encounter the same resistance on many occasions.   The best I can say is Outlook 2007 does have archiving built-in where it can offload items from the OST to a separate local PST file.  It's not hard to use and it just makes a separate folder under the user's inbox.  They can still find their items that way.  But still, the 2 GB limit applies even to archive PSTs.  Not sure if it's possible to have multiple archives.
