Resolution 1
\nDisabled IPv6 on the Exchange CAS server http:\/\/technet.microsoft.com\/en-us\/library\/cc671176(EXCHG.80).aspx<\/p>\n
In summary disable IPv6 on the NIC and make the following change to your host file:<\/p>\n
#1::1 localhost
\nxxx.xxx.xxx.xxx exchangesevername
\nxxx.xxx.xxx.xxx. exchangesevername.fqdn<\/p>\n
then IISRESET<\/p>\n
Resolution 2
\nConfigure External Exchange URL and Certificate http:\/\/support.microsoft.com\/kb\/940726<\/p>\n
If you are using a wildcard you will also need to configure the CertPrincipalName:
\nSet-OutlookProvider EXCH -CertPrincipalName “msstd:*.fqnd”
\nSet-OutlookProvider EXPR -CertPrincipalName “msstd:*.fqdn”<\/p>\n
Gotcha 2: TMG! Dam! TMG! Disable pre authentication and cache filtering!:<\/p>\n
Resolution 3
\nIf you are publishing using ISAIAGTMGUAG would suggest changing the configuration of the publishing rule as follows:<\/p>\n
On the Listener:
\nAuthentication tab: No Authentication
\nOne the Rule:
\nBridging tab: Make sure SSL-SSL is selected (SSL-HTTP is not supported)
\nAuthentication Delegation tab: No delegation, but client may authenticate directly
\nUsers tab: All users
\nUnder System \u2013 Web filters:
\nDisable Compression Filter
\nDisable Caching Compression<\/p>\n
Troubleshooting Tool:
\nHandy little testing tool by the Exchange Team:<\/p>\n
