I had 2 gmail accounts and my Rogers account on Outlook 365 on a PC with Windows 10. One day a week or so ago I suddenly could not delete messages on the Rogers account. I could still send and receive however. The account was set up as IMAP I believe. Around the same time I deleted one of the Gmail accounts and added another one.
I decided to delete the Rogers account - and try to re-install it. The system says that it is connnected and installed but messages are not being received. They are going to other devices and to the web-based Yahoo mail.
I've tried installing manually but it does not give me options to continue that -- just says that it is connected / done. I'm aware that an app password could be used. When I went to my account on Yahoo Outlook 365 is already authorized so I cannot generate a password (and have no idea what the password might be).
