Office 365 Lync Online SRV settings in Plesk DNS Control Panel

Problem:

Office 365 Lync Online SRV Records are not getting verified by Office 365 DNS.

Symptoms :

 Rest of all Records are getting verified without any issue like "CNAME", "MX" , "A" Records, but when you set SRV Records for Lync Online in Plesk DNS control penal it is not allow you to set WEIGHT to "0" and priority to "100"

Resolution :

After so many diagnose I found that removing the _ from the sip and tls setting and setting the priority and weight to 0 allow it to verify.

UNIX or Linux OS servers that host DNS don’t require the underscore (_) when you add SRV records to the DNS host. If your DNS host is running UNIX or Linux and the SRV records aren’t resolving correctly, remove the underscore from the host name of the SRV record.

After setting above value please wait for at least 10 minutes to reflect DNS records changes, it may also depend on your internet speed and DNS Propagation Speed.

now open Office 365 Admin page and change DNS settings, Select Verify domain button to verify DNS changes and hurrayyyyy!!!!! Congratulations you have successfully configured Office 365 DNS records. Now your Lync will be up and running.

hope this may help.
