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.  

 
Answer:
  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
