Cannot log in to Lync 2010

I used the configurator from https://portal.microsoftonline.com/download/default.aspx to setup my desktop apps including Outlook 2010 and Lync 2010.  Outlook 2010 is working great but I cannot login to Lync 2010.  I am getting the "Cannot sign in to Lync.  the user name, password, or domain appears to be icorrect..." pop-up error for every login attempt.

 

Here are some of the steps I have already taken to fix the issue:

 

(1) Uninstalled and re-installed Lync 2010 64 bit from https://portal.microsoftonline.com/download/default.aspx several times

(2) Confirmed that Sign In address and User name are the same (martin@rickman.me.uk)

(3) DNS records are correct

(4) Checked access to https://webdir.online.lync.com/WebTicket/WebTicketService.svc/mex is OK

(5) Deleted the user licence for Lync, signed out of Admin, waited 1hr then signed-back in to Admin to add Lync licence to martin@rickman.me.uk

(6) Run Outlook 2010 mailbox Repair wizard

(7) Removed cached sign-in data and credentials (http://office.microsoft.com/en-us/communicator-help/troubleshooting-lync-sign-in-errors-administrators-HA102759022.aspx)

(8) Tried the server address in "Automatic" mode and tried setting Internal/External to sipdir.online.lync.com:443

 

...but still no success.

 

please can anyone help?

  • Martin,

    Here are some other steps for you to try:

    (1)  Set the user to your .onmicrosoft.com domain, wait 1hour, attempt to sign-in with that login

               -  If the above works, we know the user account is correctly setup for Lync

               -  If the above works, set the user back to the vanity domain (rickman.me.uk), wait 1hour, attempt to sign-in with (martin@rickman.me.uk)

    (2)  If flipping the domain to the onmicrosoft.com domain does not allow you to login

              -  What error are you recieving now?
