Indexing Options will not stop loading Outlook 2007

I have been trying to work with Indexing Options, to fine tune what is
indexed on my system.

I have 4 partitions for different functions. So, indexing is pretty
important.

However, I have been unable to keep Outlook 2007 from automatically loading
and being indexed. I have removed it from the Indexing Options about 4 times
now and it keeps getting added back in.

I get some rather large emails and when Outlook is removed from Indexing the
emails open with no problem. But, when Outlook automatically loads back in
to the Index Options my emails are very slow to load.

Isn't there a way to stop Outlook from automatically loading itself to the
Indexing Options?

Thanks
