Office 365 basic plans quick config for Lync Mobile

If you want to have a play with the new Windows Phone client (WP7) for Lync then Microsoft haven’t quite setup the DNS records yet (or they are still propagating round the internet). Not to worry you can force it by manually specifying some URL’s…

(If your using your own domain with O365 or on one of the higher plans check these guides… Set up Lync mobile devices and Set up your network for Lync Online or my guides here for “on-premise” deployments


  • Start the Lync mobile client
  • Enter your username as: <name>@<domain>
  • Enter your password

O365 1

  • Specify a username in the same format: <name>@<domain>
  • Toggle the “Auto-detect services” & enter the following as the “External Discovery URL”
  • Chances are you’ll never be “internal” to the Office 365 network so we can probably leave the internal one clear for now..!
  • It looks like some clients throw a wobbler if you don’t give them an “internal URL” too, so just repeat the process for the Internal Discovery URL

O365 2

You should now be able to connect & enjoy having a play around.


Thanks to @richfrombechtle for giving it a test…

    I have a full internet plan with my carrier and have also tried using wifi.. Using Lumia 800 as a handset

  8. By vanity domain I mean using your own domain rather than

    Have a read of this – you might need to add some DNS entries if you manage the domains DNS yourself or this might help too?

  9. It works.

    How the hell has invented this simple address?

    This was not in Lync Mobile quick instruction and took some time to find it from here.

    Why not but this address as default or pull down option?
