regex redirect "/service" IIS 7 - regex

Question

I am new to .NET and IIS ans I am trying do a regular expression redirect with this pattern \/([^\/]+)(?=\/[^\/]+\/?$) so my url wil go from mysite.com/en/solutions/exemple to mysite.com/en/exemple but in the redirection IIS put /Service in my URL someone as a idea how to fix this?
here is the rule generated in my web.config by IIS 7
<rewrite>
<rules>
<rule name="redirect salesforce" stopProcessing="true">
<match url="\/([^\/]+)(?=\/[^\/]+\/?$)" />
<action type="Redirect" url="/en/{R:0}/coveo-for-salesforce" appendQueryString="false" />
</rule>
</rules>
</rewrite>
Thanks
UPDATE:I tried
<rewrite>
<rules>
<rule name="remove solutions from url" stopProcessing="true">
<match url="^([^/]+)(/[^/]+)(/.*)" />
<action type="Redirect" url="/{R:0}{R:1}" appendQueryString="false" />
</rule>
</rules>
</rewrite>

Please note that I am working on a Sitecore solution with 2 languages en and fr

If you want to remove the first level folder from the url, e.g.:
/en/solutions/example-page -> /en/example-page
/en/other-folder/another-page -> /en/another-page
/fr/one-more-folder/blah-page -> /fr/blah-page
with the 301 redirect code, use the following rule:
<rewrite>
<rules>
<rule name="remove solutions from url" stopProcessing="true">
<match url="^([^/]+)(/[^/]+)(/.*)" />
<action type="Redirect" url="/{R:1}{R:3}" appendQueryString="false" />
</rule>
</rules>
</rewrite>
If you want to redirect with 301 code from mysite.com/en/solutions/exemple to mysite.com/en/exemple (so in fact remove solutions from all urls (but only if they are directly after language), you can use:
<rewrite>
<rules>
<rule name="remove solutions from url" stopProcessing="true">
<match url="^([^/]+)/solutions(/.*)" />
<action type="Redirect" url="/{R:1}{R:2}" appendQueryString="false" />
</rule>
</rules>
</rewrite>
I've tested the solution on Sitecore application and it definitely works.
