Outlook Error With POP3 Account

Topic

New Reply

I hope someone can help me with this two part problem that is really a nuisance.  I am using Outlook365 on a Win10 1909 PC with a Yahoo email account.  At least once a day I get an error thrown – “0x80042104 – your email server does not have features to allow messages to be left on the server”  If I close Outlook and restart, it behaves normally and will download emails received since the error was seen.  However, and this is the second part, sometimes it will download all existing emails on the Yahoo server that have been previously downloaded .

Both of these are intermittent and I had them before updating to Office365 from Office 2013.  Unfortunately the errors are happening more often now.  I use an Android phone for checking email on the run so I don’t want to have Outlook remove things from the server.  This was the only solution I seem to have found on the Internet.

I have a second email account that requires Outlook so I really need it to play nice with  the Yahoo account.

This has just started to happen here too.  Outlook365, Win10 2004, Yahoo email.  I saw an Office update occur a couple of days ago as I launched Outlook.  I think the problem started just after that.  I know this is not much help, but at least you now know you aren’t alone with this annoyance.

This is the person who started this mess. I was running Firefox with Thunderbird as an email client.
Problems started on March 24 when I was doing something with ATT n bellsouth They asked me to change password types to encrypted I have been working off n on since then. more off then on as I got tired of no change Help!!!!!

If you are using ATT/Bellsouth/SBC or some other affiliate, your email is handled by Yahoo/OAuth.
If you use Thunderbird as your E-mail client, you have to use a 16-character key instead of your password to access the email through Thunderbird. In Thunderbird, when it asks you for the password, put in the 16-character key instead and tell it to remember that.

This link is instructions for ATT/Yahoo mail using Thunderbird. If you have mail through the other old “Bell” Companies, you will find similar instructions for what they consider “unsecure” mail clients..

What version of Windows are you using? (In the Search box, type winver and press Enter.)

I should have clarified in the original post that my ISP is Verizon and also that the receiving error that prevents further downloads from the POP3 server has NO impact on my ability to send emails from Outlook365 using the same email account.

I don’t know why my someone is asking about Thunderbird on a thread that is asking about Outlook problems.

Both Outlook and Thunderbird email clients are subject to the same authentication key restrictions using a Yahoo mail account imposed by OAuth.

Thanks but what am I supposed to do regarding intermittent errors with Outlook365.  Today I logged on at 7AM and it has run flawlessly since that time.  I use the same password for Outlook as I do for the Yahoo web and android clients.

I’m still unsure what I need to do other than just live with this.

Been having exactly the same problem:  Win10 v. 1909.  Outlook 365 v. 2007.  ISP is Comcast (so presumably ISP is not the cause?).  Started happening a few weeks ago – makes me wonder if that v. 2007 of Outlook is the culprit?

I’m wondering if it’s worth trying to roll back to a prior version of Microsoft Office.  I’ve never tried that, and from googling, it appears that in theory you can do it, though people seem to have lots of difficulty in the process?

@GaryB – I had the same problem with Outlook 2013 but not as bad as with this version.  Yesterday, Outlook performed flawlessly all day long.  today it threw an error message after four hours.  One thing I don’t know much about is whether changing it to the IMAP setting would improve things.  I have always run it as a POP3 mail server.  I confess to being a bit of a neophyte in terms of the two approaches.  Maybe @PKCano can weigh in on this.

POP3 and IMAP use the same account but a different connection mechanism.
As the issue seems to be intermittent I suspect it’s not POP3 specifically.

Do any of the other posters also use POP3?

cheers, Paul

I’m using Outlook365 and Win10. I received an update of outlook and windows 10 about the same time. Since then, I’ve random error on POP3. I thought it was from pst file. But even with fresh pst, the problem occurs again.
Don’t know what to do. It is pain in a..e. I can’t find a solution on internet.

I’m using Outlook 2013, POP 3 set-up on Windows 10.  After an update on Sept. 29 outlook won’t log on to my web server and won’t accept the correct PW with the endless popups.  Anyone  have ideas?  Even my IT guy is stumped and suggested its a MS generated big and I have to “wait for a patch from MS”.  Ugh!

There is not much to go on with your information.
What is your email provider?
Can you log in directly to your email on your provider’s mail server.
This may be relevant to your situation:

If your email is handled by/through Yahoo/OAth, there are local mail clients (Outlook, Thunderbird, etc) that they consider insecure. If you are using one of these clients, you have to create and a 16-character passkey and use it in the client instead of your password. (You still use your regular password to login on the provider’s mail server).
There was a deadline to make these changes. If you ignored the notifications, you will not be able to access the email through the clients. But you can still access the mail through a browser by logging in to the mail server with the regular password.

See this post and the thread it is in. There are three links to more information in the post.

The Yahoo deadline to change to the 16 character password was this past week.  I changed things at the beginning of the month and it was a flawless migration with Outlook from Office 365.  I will note that there have been constant issues with Yahoo and Outlook that randomly appear with no rhyme or reason.  Don’t even bother contacting Yahoo support as they seldom respond.  One thing to do is reinstall Outlook to see if that helps out at all.
