Skype for Business: "There was a problem acquiring a personal certificate required to sign in"

Hello all,

Just another quick one today. I was faced with this error this morning when arriving at my desk and thought I would share the resolution.

Multiple sign in attempts failed, even after restarting the client. After coming across this kb article I simply selected 'Delete my sign-in info'.

I was then able to sign in succesfully.

It appears there was cached user sign in credential corruption or possibly an issue or corruption with the certificate - deleting the sign in information resolved the issue.

Take care,
