For each Skype for Business client, you can sign in using the following details:
- Sign-in address: your (UT) e-mail address (e.g. firstname.lastname@example.org)
- User name: your (UT) e-mail address
- Password: corresponding password
When signing in to the Windows client for the first time, only the e-mailaddress and password can be entered. After an error message the User name can be entered.
