Help!!!

Same problem here. Going though Yahoo though.

Did you get an answer? Resolve?

I am having the same issue going through yahoo.com. New Outlook will not send nor receive (Nor would old...) . Emails sit in the outbox. Yahoo works fine on the service providers platform. Can send and receive that way. Just not through Outlook.

Outlook App on a Surface Pro 8 started asking me to log in this am.

Will not accept proper password (confirmed it is valid by using my ISP's web mail.)

Called their tech line to confirm IMAP settings.

Still can't log in.

Get this message:

{"SessionId":"d634745f-a5d1-4149-b83f-3021dab318d6","Timestamp":1739043111744,"Error":"INTERACTIONREQUIRED"}

Without naming my ISP the settings are:

incoming:

mail.xxxxx.net Port 993

outgoing:

mail.xxxxx.net Port 587

Seems Outlook keeps changing to these settings:

incoming:

imap.xxxxx.net Port 993

outgoing:

smtp.xxxxx.net Port 465

Which aren't working.

What is going on?

Especially aggravating since we can no longer use mail.

I'm having the same issues, I can't send or receive email in my Outlook for Windows 11.

It appears to be unfixable.
