Been thinking about writing a blog post about this for a while but found the same article here

Microsoft Forefront TMG – Best Practice Analyzer.

and here Forefront TMG (ISA Server) Product Team Blog Post

Whenever I make some significant changes to the TMG on our Essential Business Server at work , I run this to get a good overview of anything that I have missed.

Essential Business Server 2008 comes with Exchange 2007.

One of the most used features for EBS at work is the Outlook Web Access by our remote users. Of course it’s sometimes much more easier than opening Outlook first thing in the morning before heading to work to have a quick glance at your emails.

OWA works straight out of the box just like RWW on your EBS installation. But I have been having issues with users complaining about the following screenshot while opening contacts info at the top right hand corner of the window.

To fix the issue

1. Log onto TMG either from the Management box or from the Security Server
2. Scroll to the rule that Mentions the Outlook Web Access rule and right click and click on Configure HTTP as shown

   

3. At the bottom of the window is an option called “Verify Normalization” un tick the option as shown

   

4. Apply the changes to the TMG

   

5. Wait for the synchronization to complete which will be a minute or two depending on your configuration

   

That’s it!

Log back onto your OWA and type an users name and tada contact info

Cheers
