Mac OneNote continually asks for sign in when relaunch

Question:

Every time I open OneNote, I have to sign in again in Mac.  OneNote is always asking me to sign in.  Every single time I boot up.  If I restart OneNote after signing in, it will ask me again for sign in again.

1. Make sure all Microsoft programs are closed
2. Open the Keychain Access app
3. In the search box at the top right of Keychain Access, type in "microsoft" without quotes
