Hi TracyBooth,
I'm Charles, an Independent advisor trying to help.
If you have the latest updates on your computer, check if these steps solve the problem as an initial step:
1.- Windows + I >> Configuration >> Applications >> Applications and features, now look in the list for the option >> Mail and calendar (Click on the option) >> Advanced options >> Reset, finally restart your computer and add account again
I hope the steps works for you too
Attentive to any comments
Have a happy day
Best Regards,
Charles.
