How does it work?
Support and Recovery Assistant works by running tests to figure out what’s wrong. It can fix many problems for you, or it can tell you how to fix them yourself.
What if I’m still having problems?
If Support and Recovery Assistant can’t fix a problem for you, we’ll suggest next steps and help you get in touch with Office 365 support.
