|Authentication and provisioning issues||These issues typically occur for specific kinds of users (for example, federated users or users who are on a specific domain) or for a specific user who may not be entering his or her sign-in address or password correctly.||Incorrect password or sign-in address, unlicensed user, Active Directory Federation Services (AD FS) not working correctly|
|Networking issues||These problems can affect large groups of users at a specific site or network location. They can also affect users who have a specific domain.||Domain Name System (DNS) for AutoDiscover not set up, proxy or firewall exceptions|

Service-related issues can affect certain kinds of users (for example, users in a specific geographic region or users on a specific Lync server).||Skype for Business Online service down, tenant subscription expired, Azure AD Authentication service down|
