Opened up a Microsoft Office 365 account for emails. Everything worked yesterday. Today I turned my computer on and emails downloaded. Later I tried to send an email and it gave me an error message: Enter your password for [edited]@thechartstore.com on outlook.office365.com: I re-enter the password and it still will not send. I checked to see what password is saved in Thunderbird and it is the correct one. This email is working: [edited]@mymetronet.net for correspondence via email. Thanks for any assistance.
