PROBLEM

When a federated user tries to sign in to a Microsoft cloud service such as Office 365, Windows Azure, or Windows Intune from a sign-in webpage whose URL starts with https://login.microsoftonline.com/login, authentication for that user isn't successful. Instead, the user receives the following error message:
Sorry, but we're having trouble signing you in

Please try again in a few minutes. If this doesn't work, you might want to contact your admin and report the following error:
80048163

This issue may occur if the following steps were performed:
  1. The on-premises user object is first provisioned by using Unicode characters that aren't supported by Windows Azure Active Directory (Windows Azure AD).
  2. Directory synchronization is then run to create a user ID that has the same characters.

SOLUTION

To resolve this issue, make sure that the user's user principal name (UPN) contains only supported characters. Sign-in fails if the UPN contains characters that aren't supported.

MORE INFORMATION

Microsoft cloud services supports the following characters in the UPN:
  • Alphanumeric characters (uppercase and lowercase)
  • Period (.) as long as it does not appear directly before the at sign (@)
  • Hyphen (-)
  • Underscore (_)
For example, the following UPN is supported:
aA13.b@contoso.com
However, the following UPN isn't supported:
aA13.b.@contoso.com
