To Whom It May Concern:
I am unable to login to Skype for business on any device; iPad, iPhone and/or MacBook.
When attempting to login, I receive a message that states, "We can't sign you in". In an effort in resolving this issue, I performed the steps outlined in Troubleshooting Skype for Business Online DNS configuration issues in Office 365, but am still unsuccesful in my attempts.
Pleae see the attached image for details (I have removed my login information, as I only want to point out the error message).
Any assistance provided would be greatly appreciated.
