I'm having a minor issue with the Lync RT App and was hoping that someone may be able to point me in the right direction to get it fixed.
We have Lync 2010 Server installed and we are running Exchange 2010 SP2. Outlook Anywhere is published via TMG 2010 and our Outlook clients can connect.
We have Lync Mobile deployed and also remote users can connect to Lync OK as well although the full Lync client does give an error about not being able to connect to Exchange if they don't have Outlook installed and connected before hand.
Is this to do with how the EWS is published and how do I fix it if it is?
Thanks in advance for any pointers.
I suggest referring to the following tips to check the issue.
In this user's Lync, please holding down CTRL and right-clicking the Lync icon located in the System Tray and click Configuration Information . Please check if the status of EWS information is ok. Please also check if Value of EWS Internal URL and EWS External URL is correct.
On user's client, please go to HKCU\Software\Microsoft\Communicator\[User SMTP Address]\Autodiscovery, please check if the URL of the
following items are correct:

Thanks for your input. Unfortunately there is no tray icon for the Lync RT App BUT...
I setup a Lync 2010 client on a Windows 7 PC as an external user and although it auto-detected and connected OK it reported problems connecting to Exchange.
I cancelled out of the MAPI login as I wanted to rely on EWS as the Lync RT App has no Outlook client to fall back on.
I then did as you suggested and got the Configuration Information. The output from the Configuration Information is at the bottom of my reply.
There was no ExternalEwsUrl or InternalEwsUrl.
I looked at the reg keys and there were urls listed. I browsed to the exteral url and got prompted for a username and password by a TMG form (similar to the one we get when using OWA). When I entered my username(using a UPN which matches the sip account and password) I got an XML page (same as when I browse to it internally and everything works fine for internal users).
I tested Outlook Anywhere access and it works fine and Autodiscover configures Outlook 2010 OK.
I have been to www.testocsconnectivity.com and got passes all the way.
What do I need to do as the EWS virtual directories are configured to use Basic Authentication as seems to be recommended and Outlook Anywhere is published via TMG.
Thanks again for responding.

I notice that you are using TMG. I have noticed on my TMG server that the Lync client only appears to be attempting connections anonymously. Since my Exchange rules require authentication, it is failing. I see similar behavior with the other Lync clients, but they eventually fallback and authenticate.
The only way I have gotten it to work so far is to remove all authentication from my listener and rules. Then the client will talk to the server. Otherwise, TMG blocks it since the communication is anonymous.
I hope you find something different, because this sort of defeats one of the reasons for having TMG.
