I'm trying to log in to skype for business on a mac and receive the error: 'You're not configured to connect to the server. Please contact your support team' This is while connected to our corp wifi or Ethernet. Skype for Business uses these ports and protocols: 5061 TCP (SIP) - Used for SIP/MTLS authentication of A/V users. Communications flow outbound through the internal firewall 443 TCP (HTTP) - Used by Skype for Business clients/Lync connecting from outside the intranet for SIP communications.
A Skype for Business Online (formerly Lync Online) user tries to sign in to the Lync 2010 mobile client from a Windows Phone, Apple iPhone or iPad, Google Android, or Nokia Symbian device by using the Auto-Detect Serveroption to determine the Skype for Business Online server. However, the user receives the following error message:
Solution
To troubleshoot this issue, follow these steps.
Step 1: Verify the Lyncdiscover CNAME record
To verify that the Lyncdiscover CNAME record is present in the Domain Name System (DNS) records, go to the Lync Connectivity Analyzer, and select Office 365 Custom/Vanity Domain Name Settings Test for Lync. Enter the sign-in address that you're using when you to try to sign in to Skype for Business Online (for example, [email protected]), and start the test.
If any issues are detected, check the DNS configuration with your domain registrar.
Step 2: Try a Wi-Fi connection
After you verify that the Lyncdiscover CNAME record exists in DNS, check whether a Wi-Fi connection is available. If a Wi-Fi connection is available, try to connect to Skype for Business Online. This test determines whether the DNS lookup failure is occurring on the mobile carrier, the Wi-Fi connection, or both.
Step 3: Query DNS from the mobile carrier
The next step to check whether the mobile device can resolve the Lyncdiscover CNAME record in DNS is to query DNS from the phone itself. This is difficult to do because most mobile devices don't include integrated network diagnostic tools. So, users have to download an application that performs these kinds of functions. Demonstrating the use of these applications is outside the scope of this article and outside the scope of Office 365 technical support. You may need to contact your carrier for additional assistance if the connection is only failing when connected to your data carrier.
More Information
This issue occurs if the Lync Mobile Autodiscover process fails and the user's Skype for Business Online server can't be determined. This issue may occur if one of the following conditions is true:
The Lyncdiscover CNAME record isn't set up.
The Lyncdiscover CNAME record is set up incorrectly.
The Wi-Fi connection is blocking DNS queries.
For the Lync Mobile Auto-Detect Serveroption, specific CNAME records must be present in DNS for the Lync 2010 mobile client to determine the home server of the Skype for Business Online user. The Lync 2010 mobile client tries to discover the user's home server by querying the following CNAME records in DNS:
LyncdiscoverInternal.<domain>
Lyncdiscover.<domain>
Additionally, the CNAME records in DNS must meet the following criteria. Otherwise, the Lync Mobile sign-in process will fail if the Auto-Detect Server option is used.
DNS Record Type: CNAME
Name: Lyncdiscover
Value/Destination: webdir.online.lync.com

autodetect was't working when i was connected on-prem... interestingly, it worked fine when i was external so i knew i had a shot... i've seen this issue mentioned in numerous other support forums
typical error message: You're not configured to connect to the server.
steps that worked for me:
Skype For Business Mac You're Not Configured To Connect To The Server Free
pull working Windows configs by CTRL+RightMouse on Skype tray icon > Configuration Information
based on educated guess i took the 'DG URL Internal/External' https: urls and plugged them into skype's [advanced options] page
also on windows, i also exported the certificate from the browser for the above server and imported it into mac's keychain
i exported the .p7b format INCLUDING the parent certificate chain
i imported as 'system' level
and made sure to TRUST it after it was imported (in mac KeyChain Access app, search by server name, right mouse on the entry > get info > trust)
