An annoying repetitive popup message from Yahoo! when I'm looking at my emails on my laptop stating "You're in another email app" I don't know how to get rid of it.
Using Classic Outlook on Windows for personal email, calendar, and contact management
Just FYI - Looks like a similar case
added my email + password to log in - then nothing other than my yahoo email list. Not aware of changing anything.
Thanks!
Do you use another email app besides Outlook, such as the Yahoo app? Open Windows Settings > Apps > Installed apps > Look for any Yahoo app and uninstall it.
If that doesn't work, or if you don't have a Yahoo Mail app, remove and re-add your account:
control > Under View By, select Large Icons > Click on Mail (Microsoft Outlook).WARNING: If your email is POP, you should back up your Data Files as a precaution in Documents > Outlook Files.

Actually for any IMAP or POP account (like Yahoo in Classic Outlook) any Outlook Folders marked "(This Computer Only)", usually Contacts and Calendar, will be lost when the Profile or Account is removed.
To back up any of these local "(This Computer Only)" folders, see the section "1 -- Export any "This Computer Only" folders" the Answer by "Hornblower409 Apr 16, 2026" at

Instead of your regular password, you must generate and use an App Password provided by Yahoo.
The recommended authentication method for Classic Outlook connecting to a Yahoo account is now OAuth.

Hi!
I believe the message is the login screen asking for access confirmation. Could you send me a photo of that message? Please redact any personal information before posting.
Does that pop-up have fields to enter an email and password, or an option to log in? If so, have you tried logging in?
Have you changed your password or updated any email-related information recently?
