Skype for Business / Lync Desktop and Mobile clients (for iOS, Android and Windows Phone) can be set up with user's email address and mailbox password only (without the need to enter Internal and External Discovery URLs).
To enable server auto-detect feature to automaticallly set up Skype for Business / Lync Desktop clients, you can add the _sip._tls. SRV record:
Type Host Priority Weight Port Lync server SRV _sip._tls.yourdomain.com 0 0 5061
lyncsip.exch0XX.serverdata.net for the Exchange domains < EXCH082,
skypesip.exch0XX.serverdata.net for the Exchange domains > EXCH083
sip.exch091.serverdata.net for EXCH091
Note: the correct settings can be found under CONTROL PANEL > Services > Domain Name > Click on your domain name > Display DNS records > Show System Records. Read the Knowledge Base article on How To Add SRV Record To Your Domain for more information about SRV record syntax.
To allow autoconfiguration for both desktop and mobile clients, you can add the CNAME records to your domain:
lyncpool1.exch0XX.serverdata.net for the Exchange domains < EXCH082,
skypepool1.exch0XX.serverdata.net for the Exchange domains > EXCH083
pool1.exch091.serverdata.net for EXCH091
Note: the record is needed only for Exchange features (e.g. conversation history)
Note: correct records for your account can be found on the Home > Exchange servers and settings page. In lyncpool1.exch0XX.serverdata.net / skypepool1.exch0XX.serverdata.net, exch0xx should be replaced with the Exchange Domain for your account. Autodiscover record is also shown on this page. Read the Knowledge Base article on What Is An Autodiscover Record And Why Do I Need It? for more information.
Important: currently the CNAME
lyncdiscoverperformance for Skype for Business servers (Exchange 2013/2016 customers) may be unstable and may cause issues with joining conferences and even configuring devices. We recommend using manual setup. Clients that not allow manual setup are not supported at the moment.
Once the above records are in place, users with primary email address [@domain.com] can set up Lync using the following settings:
- Sign-in Address: primary email address of the mailbox
- Password: mailbox password
- User Name: primary email address of the mailbox
- Auto-Detect Server: ON
