I installed lookout (outlook plugin) in outlook 2007 on windows XP and it works fine. I am now trying to do the same thing on WINdows 7 (using this link) but it immediately crashes outlook when it starts indexing.

Here is a screenshot of the crash that i see:

Does anyone know how to get lookout to work on windows 7 and outlook 2007?

Stop trying to use out-dated and un-supported software, and use the built-in functionality instead. – Iszi Mar 9 '12 at 13:50
@Iszi - i would be happy to do so but i can't find any software that is as good as lookout . . feel free to challenge me on that – leora Mar 9 '12 at 14:09
@leora In my experience, the built-in search indexer for Outlook (which is integrated with Windows Desktop Search) is just as good as Lookout ever was. – Iszi Mar 9 '12 at 18:49

It looks like someone added a comment to the link above. TO get it to work on Windows 7, you need to disable outlook search and then lower the "aggressiveness" chart on lookout and it will not crash anymore.

To avoid error "Outlook 2007 has stopped working", lower the amount of resources used in Lookout Options → Advanced → Indexer Aggressiveness.

This is more of a workaround then a fix. Lookout seems like a peice of crap software. Eset's outlook add-on has no problem. – Ramhound Mar 9 '12 at 15:35
@Ramhound - i am not sure what you mean by "seems like a piece of crap software". have you used it? it works beautifully . . what is Eset addin ?? – leora Mar 9 '12 at 17:40

See VLAD link below, which worked for me.

Actually, Lookout worked for me ok with this small change ( using the CMD rename hash but then an update was installed for Outlook 2007 on Win7 and Lookout started to crash.

I tried the CMD rename thing again, and Lookout would open, but would crash on indexing.

I am happy I found the patched dll files on Vlad's website. Using them on Lookout 1.20 works for me, like a dream. And also saves messing with the CMD prompt.*/

Happy indexing!

My recommendation: Use Software which is up to date. Lookeen is a good alternative for Lookout - although it is not for free. But test the 14 days free trial if it's worth the price. Download it at

Disclaimer: I work for Axonic - vendor of Lookeen.

if this isn't spam, i don't know what is. – Sickest Sep 17 '14 at 15:36
Well he's followed reasonable disclosure, though it dosen't quite answer the question. I'd add though that with a single answer, its pretty hard to tell if he's going to follow the 'don't just answer questions to promote your product' rule. – Journeyman Geek Sep 18 '14 at 0:32
Thanks for the feedback. I really know Lookout and its technical and business history very well. But it's like Iszi posted at the first answer: There is no perfect way to get software run on current systems which was stopped and removed more than 8 years ago. For sure I work for Lookeen - but we're trying to fill the gap Lookout produced and give users a better Outlook search. Please note: BEFORE Lookout was bought by Microsoft it also was with costs!!! – Peter Oehler Oct 2 '14 at 12:00
