Hopefully that could be a start.

I’ll get back here with an update in a few days. I think my best chance is to explore the Outlook link jb posted and try and figure out how to get the emails sent to my outlook to show in my inbox.

Thanks. I’m going to try to figure this out. Hopefully your link will lead to something.

I look forward to your update.

If you take my advice to migrate and delete your address book in Yahoo, keep a copy of that address book somewhere in case things go south with your new email address. The thing about protonmail is that since it is encrypted the emails in your account may not be searchable.

Unfortunately the update is not good. I messed around in Outlook for a couple hours and just went around in circles. I’m not very tech savvy and it’s frustrating. I don’t have filters and I have like .1 used of available space so I can’t understand the problem. I feel I’m missing something obvious but can’t think what it could be. It appears I’m not going to be able to get back into my yahoo email so I will try to create a proton mail and see how that goes. I appreciate all the suggestions.

Email your ISP. Sometimes they filter what they think is spam so it never reaches your email software.

If you also have a gmail set up on your computer or laptop, you might have passwords saved into a "password manager," already on your computer. Have you checked or heard about that?
