Hi JudithCain-4875,
Does this issue occur with other applications when logging into your account? Such as going to www.office.com on web browser.
- When the web page loads smoothly with your account signed in, your internet connection is working. I suggest you try to reset your credentials.
- If you still could not log into your account on www.office.com, it's best to change the network or check whether the password is correctly.
In additionally, here is a guided walk-through to have a check. It would help you troubleshoot this question and provide some suggestion according to your selection.
Hope the information could be helpful.
Any questions please feel free to tell us.
