Issue

Lync Mobile Client won’t sign in.
Mobile client logs contain the error E_AuthError E2-3-2
Tests from testconnectivity.microsoft.com are successful.

NOTE
If the tests from testconnectivity.microsoft.com are unsuccessful then you may need to recheck the user credentials

Reviewing the logs from the mobile device you find the following error messages:-

  • 401 – Unauthorized: Access is denied due to invalid credentials.
  • You do not have permission to view this directory or page using the credentials that you supplied.
  • Received webticket resposne with status E_AuthError (E2-3-2)
  • Mapping error code = 0x22030002
  • Mapped error message is ‘We can’t sign you in. Please check your account info and try again.

Clearly there is some issue with your credentials.

If you go back to the testconnectivity.microsoft.com  site you will recall being prompted for Domain\User Name (or UPN)

Skype Mobile Connectivity failure

Cause and Resolution

The issue is that the mobile client does not require or prompt the user for the Domain\User Name (or UPN). The field is actually a little hidden and thus often overlooked. You can find it in Show Advanced Options.

TIP

If you enable UPN Naming for the user account and the SIP address is also the UPN address then the mobile user does not need to provide the User Name in Advanced options.

Problem
Can’t connect to Lync MCX service. Http Error 403 Forbidden, Lyncdiscover Http Authentication Test failed when testing https:///Mcx/McxService.svc
Also get Authentication Test failed from http://www.testocsconnectivity.com/
Solution
Error was the TMG rule
The error here says that the Credentials for the request to the site were deleted. It also explains how no delegation is set and user authentication isn’t enabled. Of course this needs to be enabled!!!

Re-installing MCX

While attempting to repair a problem with a clients self installed Lync FE IIS services I came to the conclusion that the Web Components Services was broken. No problem, right?
Simply uninstall the Web Components and then re-run the Deployment Wizard. I did that and returned to IIS to see MCX now missing. Suppose I should have expected that. No problem (again), I’ll just run the MCXStandalone.msi…
So the .msi says that the MCX is still installed, did a remove and ran it again to re-install. Done.

Checked IIS and MCX has returned, only problem is it still doesn’t work when I run the www.testocsconnectivity.com test.

So what’s the issue?
For one thing, the Environment had been installed and updated to CU6 but the MCXStandalone was still on the relative CU4. The MCX Update was found here

Secodly I assumed that the MCX listening ports were still defined as you usually cant install the MCX if they aren,t. Better safe than sorry, so I re-ran them too

Set-CsWebServer -Identity -McxSipPrimaryListeningPort 5086
Set-CsWebServer –Identity  -McxSipExternalListeningPort 5087

I restarted all the services for good measure, probably wasn’t necessary.

And voila!
