GMail rejects valid credentials in Outlook 2010.

Hello Experts:

One of my clients was using Outlook for his Gmail account.  It worked fine for several years.  Suddenly, it just stopped working.  The Gmail servers began to reject his credentials.  I logged onto his account, using the credentials he gave me and they worked.  But those same credentials fail in Outlook 2010.    I checked and double checked all the settings and found everything in order.  
I repaired Outlook; I verified that POP was enabled on his PC.  All the settings are correct (I've checked and double-checked them).  

I’ve run out of ideas.  Does anyone have any suggestions?

Thanks

You could either turn on 'allow less secure apps' or setup an 'app password'.

The latter is best.

gmail periodically makes changes to bring their email service into line with current standards and better practices.  I suspect this has happened due to the suddenness of the problem occurring.  These changes are not, alas, always communicated to the people who would be affected by them.

I would suggest coming forward to a more recent email client such as Thunderbird or a much more recent version of Outlook.  Both of these applications can automatically set up a working configuration for gmail accounts using the commonly-used-applications interface at the remote end.

This problem is going to get worse as time goes on.  All versions of SSL are now obsolete and TLS 1.0 is strongly deprecated.  Newer cipher suites will become standard and older clients won't be able to communicate with newer ones.  POP3 is rapidly becoming obsolete, support for it will probably disappear in the next five years -- and a good thing too, because IMAP is far superior.  Like it or not, sometimes we are dragged kicking and screaming into something newer.  Not necessarily better, but newer.

I'm no tfamiliar withthe app password solution.  I've looked at some websites but unfortunately, tha tonly confused me more.

Fist question:  Is it set up ion GMail or Outlook?  I tried it from my GMail account and the landmarks are not as described.  So I was unable to set anything up.

Any assistance you can provide in this.... I'd very much appreciate.

I can upgrade him to a newer version, but I really don;t see where hte settings are any different.  I hate to purchase a newer version o fOffice if I'm unsure of the success.  Do you have any documentation to verify this as  a solytion?

Thanks

What is REALLY baffling is that if I go to GMail, it works!  Why would the mail server reject valid credentials, just for a 3rd party program?  I don't understand

Hi thedslguy,

Easiest one to check and test is the 'less secure apps' setting.

Make sure you are logged into the Gmail account, then go to this location:

https://myaccount.google.com/lesssecureapps

If it is off, turn it on, then try Outlook again (I can't remember, but probably best to close Outlook first, then re-open once the setting is turned on).



If that doesn't work, you can try an app password (actually a better option, and only slightly more work to implement).  These are the current instructions as far as I know:

Create & use App Passwords

    Go to your Google Account.
    On the left navigation panel, choose Security.
    On the "Signing in to Google" panel, choose App Passwords. If you don’t see this option, then one of these must be true:
        - 2-Step Verification is not set up for your account.
        - 2-Step Verification is set up for security keys only.
        - Your account is through work, school, or other organization (and your admin has disabled 2-Step Verification)
        - You’ve turned on Advanced Protection for your account.
      in which case you need to change whichever it is.
    At the bottom, choose Select app and choose the app you’re using.
    Choose Select device and choose the device you’re using.
    Choose Generate.
    Follow the instructions to enter the App Password. The App Password is the 16-character code in the yellow bar on your device.
    Choose Done.

Most of the time, you’ll only have to enter an App Password once per app or device, so don’t worry about memorizing it.

Thanks,

Alan.

"On the left navigation panel, choose Security"  What is a "Navigation Panel?  And where on the left?  I see "About"  and "Store".

I Earlier, I did a lot of just guesswork clicking and wa able to find "Signing in to Google", but not where I would have expectedd it.  And no "Security" because no left navigation panel.

Would you be willng to save and send screenshots?

Thanks

Hi tdg,

If you are signed into the Gmail account, this link takes you to the security menu:

https://myaccount.google.com/security

For me, 'Signing Into Google' is the second panel down.


Does that help?

Thanks,

Alan.

Mine looks just like that, but my client still wants to use Outlook.  I'm using the latest version.  I've been offline for a while, but I still haven't been able to resolve this for him.

I'm considering closing the question and convincing him to use a different program.

I'll update when I have something more to tell everyone.
