Office 365 Single Sign-On (SSO)

Office 365 Single Sign-On (SSO)

When the users are synchronized with their Office 365 account then they are able to sign into their accounts using those Office 365 credentials. The problem arises when users forget their password so they try the hit and test method for logging into their office 365 account. Another irritable pattern is to enter the credentials every time when the users try to log in.
