Cant Review and Sign

Hello Adobe Community,

Trying to help one of our customers with their Adobe.

When clicking on review and sign from the Outlook email, it takes them to the following page  

- Tried opening it in another browser but it still does the same thing.

Tried clickinig on Adobe Acrobat Sign linkon top but and when we sign in I get the following error 

We do have Adobe Acrobat installed on the machine.
