The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

For the best security on an Exchange 2007 deployment, I really don't want to open up port 80 on the firewall. I will be using SSL certificates for OWA 2007 from Verisign.

Asked by bignewf in Exchange Email Server, Outlook Groupware Software, Encryption for Network Security

I am deploying client access servers in exchange 2007. I plan to use SSL cerificates from Verisign with OWA. However, many outside users with legacy web browsers might not be able to connect with https   Are there any functions in OWA 2007 which require http?  I really don't want to expose the internal lan to port 80 if not necessary. An ISA reverse proxy setup will be deployed later, but now we need the client access server behind the inside firewall (not in the dmz) and OWA up and running. I can see the help deskphones ringing off the hook from the external users who can't connect via http if their browsers are not patched.  With only SSL port 443 open with a signed certificate from verisign,, there is a higher security configuration on the OWA deployment.
