Yahoo via POP

Outlook version
Outlook 2016 32 bit
Email Account
IMAP
Operating system::    Windows 11
Outlook version:     365
Email type or host:    POP, IMAP

A friend of mine had been using Outlook 365 to access her Cox email, which had last year been outsourced to Yahoo. She liked POP protocol.
Then it stopped getting email on Jan 14.
I tried deleting the account and re installing.
Then the same for the profile.
Then I uninstalled/reinstalled Outlook.
Each time it self tested and said it was fine.
but it never received any mail.
Then I wondered if it could be due to POP.
I asked Google AI and it agreed that was most likely the problem, that Cox/Yahoo was not supporting POP anymore.
I thought it was worth a try.
I reconfigured using IMAP and it sends/receives fine.
I have the old pst file open in Outlook for her to access.

But it has created a logistical nightmare. She has 42,000 emails in her old inbox in the pst file.
3000 emails in the new IMAP Inbox.
I guess that's due to the way her POP was set up, removing them from the server.
(I got Outlook set to show the Total Number of Emails in each Inbox, not the Unread Number of Emails)

When I go in via the Yahoo web interface, I only see about 3000 emails in the inbox.

But now we need to get rid of the 3000 or so duplicates in the pst file because she needs to refer back to them frequently.
Any ideas?
Thanks

Did you use an app password? POP requires an app password- IMAP does not as it brings up the yahoo login page.

For regular yahoo accounts, get the app password in the account > security section. I think cox uses that page but some (like AT&T) make you log into their website to access it.
 
Yes I was using the app password when I was attempting to get POP working. It accepted the one you referred to, on the Yahoo/Security page.
And Outlook was happy with it, and it passed the Outlook "check settings".
and while the account could send email, it was never able to receive any.

When i set up IMAP, I think I had to use the app password, but I can't say for sure.
But everything is going ok now she says in her emails to me.
I will talk to her tomorrow.
 
When i set up IMAP, I think I had to use the app password, but I can't say for sure.

It depends on your version of Outlook and license. I can't recall if cox accounts pull up the yahoo log in screen - if not, then you need the app password.
 
This is the best answer I have ever got. Thank you for the information.
