Publishing Exchange Server 2013 using TMG

Thx for this article

i actually use a VM with ISA to publish my Exchange 2013 lab.

everything works fine except outlook 2013 bing map.

i added the specific rule with an higher priority than OWA rule.

Of course, i replaced ExchangeGuid and domain suffix as described in the article.

From an external mailbox, i sent a mail with the following address in the body "123 Fifth Avenue, Kirkland, WA 98033".

When i open the message from Outlook 2013 (Outlook Anywhere) or from OWA, i don't see the Bing's map button.

I checked ISA logs, i don't see requests with the following path /owa/exchangeguid@domain/*

Mail apps are enabled.

I probably missed something but what ? :)

thx for your help
