A Laptop running outlook 2010 will not connect via HTTPS to Exchange 2007

Hi there,

I have a user with a laptop running Windows 7 Pro (64bit) and Office 2010 pro.

On the office LAN the Laptop runs Outllok 2010 ok, connecting to a SBS 2008, the client has the private security certificate loaded and OWA can be used without any warning message.

Outlook anywhere appears to be setup correctly and I have created the same account details on another laptop and tested the RPC/HTTPS connection, which worked fine.

No malware has been detected by either Symantec or malwarebytes. The user doesn't want the machine wiped and rebuilt.

I have attached a connection status screen print.

Any ideas?

Is it just the one user with a problem (out of several) or is this the only user trying to access Outlook off-site?

Have you run the Outlook Anywhere test on https://testexchangeconnectivity.com for the problem user to see if any errors are reported?

Hi Alan,

User is the only one using this method at the present, but previously several people used it and it seems to work for me, but I'll recheck that.

Hadn't tried testexchangeconnectivity (didn't know about it).

Ok results follow;

test failed RPC overHTTP connectivity..

Steps;
Resolved host name OK
testing port 443 ok
SSL cert ok
IIS config for client cert ok (not required).
testing HTTP authentication methods OK
Ping the RPC proxy - OK

Attempt to ping the MAPI Mail store end point with id mail.clientserver.co.uk:6001 FAILED
     RPC_S_SERVER_UNAVAILABLE

Thanks for your help.

Okay - as this is SBS, can you please re-run the Fix My Network Wizard and then re-test.

Might have to run the Setup My Internet Address Wizard again (being careful to choose the right FQDN for SBS as the default is remote.domainname.whatever).

If that doesn't fix things, then we can try some other things.

P.S.  The test site is a very handy resource for sanity checking your server when things don't work :)

Interesting result - well done on finding it.

Odd that the Test on the test site threw that error.  Presumably it's happy now?

Alan was a great help in getting me to look at the problem in the right way, but the issue was completely separate from the diagnosis he was taking.
