Hi Everyone, We have an Exchange 2010 server with a paid for SSL certificate from Comodo. We can access the website (https://mail.mycompany.co.uk) with no issues. We're trying to configure remote access on some mobile phones that have native Mail for Exchange clients. When I try and synchronise a phone with an account it will fail, and the following is logged in my exchange servers event viewer: - < Event xmlns =" http://schemas.microsoft.com/win/2004/08/events/event " > - < System > < Provider Name =" Schannel " Guid =" {1F678132-5938-4686-9FDC-C8FF68F15C85} " /> < EventID > 36887 </ EventID > < Version > 0 </ Version > < Level > 2 </ Level > < Task > 0 </ Task > < Opcode > 0 </ Opcode > < Keywords > 0x8000000000000000 </ Keywords > < TimeCreated SystemTime =" 2010-09-16T12:43:46.313764600Z " /> < EventRecordID > 9718 </ EventRecordID > < Correlation /> < Execution ProcessID =" 484 " ThreadID =" 520 " /> < Channel > System </ Channel > < Computer > mailserver.domain.local </ Computer > < Security UserID =" S-1-5-18 " /> </ System > - < EventData > < Data Name =" AlertDesc " > 10 </ Data > </ EventData > </ Event > From that message I've looked up that eventid and alert number (10) and found this : http://msdn.microsoft.com/en-us/library/ff476074%28VS.85%29.aspx The error message seems to relate to : TLS1_ALERT_UNEXPECTED_MESSAGE. However, apart from this I'm unsure of where to go next. As I've mentioned browser access to our OWA is fine, all our browsers accept the certificate and confirm it's valid. Any help would be appreciated. Thanks, David

Can you test Active Sync from this website and report the issues: https://www.testexchangeconnectivity.com/Tim Harrington - Catapult Systems - http://HowDoUC.blogspot.com

Hi Tim, I performed the test with the following outcome: An ActiveSync session is being attempted with the server. Errors were encountered while testing the ActiveSync session Test Steps ExRCA is attempting to send the OPTIONS command to the server. Testing of the OPTIONS command failed. For more information, see Additional Details. Additional Details A Web Exception occurred because an HTTP 401 - Unauthorized response was received from IIS7

401 is an authentication issue. Let's start with the cert...did the ExRCA give you any warnings or errors with the certificate? Can you go here: http://www.digicert.com/help/ and see if you have and Cert chaining issues?Tim Harrington - Catapult Systems - http://HowDoUC.blogspot.com

Hi Tim, Both apps have no issues with the certificate.

Are you going through a reverse proxy (ISA/TMG)? Another thing to try is recreating the ActiveSync VD. See this: http://www.howexchangeworks.com/2010/06/reset-virtual-directory-in-exchange.htmlTim Harrington - Catapult Systems - http://HowDoUC.blogspot.com

Hi Tim, That option isn't visible for me.

I am sorry, what verion of exch with SP level? If not on Exch 2010 SP1 then you will need to use the shell: http://technet.microsoft.com/en-us/library/bb124752.aspx http://technet.microsoft.com/en-us/library/aa997160.aspxTim Harrington - Catapult Systems - http://HowDoUC.blogspot.com

Ok I've removed and re-added it via the shell. Still the same issue. Plus it now doesn't appear in the management console gui, but powershell confirms its existance.

Installed SP1, tried the recreating the ActiveSync VD via the GUI, which said it completed, but now the directory is gone from IIS itself and the gui Not impressed with exchange 2010 at the moment, has to be said... Edit: Recreated it via the shell again which has appeared, but still getting HTTP 401 errors.
