Use the Desktop Outlook App (downloaded to the computer)
Then, select "+Add Account"
Type in the email email@example.com in the highlighted section and select "Next." Don't worry about the other fields.
This dialogue box will then show up.
After a moment, a small login box should pop up that already has firstname.lastname@example.org. When you see this, type in your BYUI username with @byui.edu at the end, and then use your actual BYUI password. MAKE SURE you check "Remember my credentials."
This dialogue box will show up. Click "Finish" and restart Outlook.
