Lync Online: Cannot sign in because the server is temporarily unavailable

When trying to sign in to Lync Online client, you may encounter this error:
Possible reason for this error is if you have not created the DNS records required for Lync Online.
When you add and verify a domain with Office 365, you can choose what services you want to use with the domain. If you choose to run Lunc for the domain, you will need to create two SRV records in the domain's public DNS as below:
which the yourdomain.com should be replaced with the domain you have added and verified with Office 365. Adding above DNS entries will resolve the issue with Lync client.

Some registerars such as 1and1 don't let you create SRV and TXT type records in the DNS. If that is the case, you will need to configure each and every Lync client in your organization to manualy point to Lync Online servers on Office 365.

To do so, open Lync and go to Lync Options:
Click on Advanced button next Sign in Address in the Personal pane:


In the Advanced Connection Settings, change the coniguration setting to manual and change both Internal and External server names to sip.online.lync.com:443. confirm changes and restart Lync.

Lync Online: Cannot sign in because the server is incompatible with Microsoft Lync 2010

When for the first time you try to login to Lync Online after a fresh install using your Office 365 user account, you may get this error:
One of the most likely reason for this error could be in the case that you have been a BPOS customer and you still have Microsoft Sign In Application installed on your PC/laptop. 
In this case, Lync probably has picked up the OCS server information from the Sign In application which means the Internal and External server names are pointing to BPOS.  You can check this by going to Lync Options:

and in the Personal pane click the Advanced button next to Sign-in address field:


If the connection setting is set to Manual, it is more likely pointing to pool1.oconline.microsoftonline.com:443 which is the address of the Office Communication Server on BPOS.
you need to change the Internal and External server names to point to Lync Online on Office 365 which is sipdir.online.lync.com:443

save the changes and exit the Lync Options.
Now you will need to restart Lync client. Once Lync is restarted, you should be able to log in using your Office 365 credentials without any errors.
