suddenly can't retrieve email using Outlook Express

(1/4) > >>

We have used Outlook Express 5.0.6 (POP) running under OS 9.2.2 for several years as our email application. About 3 days ago we could no longer retrieve gmail and started receiving the following error message whenever we do a Send and Receive. Sending emails works fine.

Could not retrieve mail from the account
The identity certificate uses an unknown signature algorithm
Error 3006

We can access gmail on our iPad and using Classilla 9.3.3 on our G4.

What can we do to get this working again? Also, does anyone know where I could download a free copy of Eudora 6.1.1? The most recent version I have been able to find is 5.1.

Thank you,


Did you activate legacy support under gmail? Thats the first thing that happend to me. How do you pull the mails (imap/pop) of the server?

We are using POP. Your legacy idea sounds like it could be a possibility. I looked but didn't see a clear explanation of what it is, how to find out if I am already configured that way and if not, how to make the change. Can you provide more information? Thank you!

Pretty easy. I started the app and couldnt login. Then i got a gmail message that a legacy app was trying to connect. In that message is a link where you can enable that. But i cant give you the link becaus it would take you to my account. Check you gmail emails.

this is because of google instating more security

i just got a msg from google via email to my account stating that the sign in attempt was blocked when trying to use windows xp's version of outlook express to sign into my gmail account + send a msg..

Hi Chris,
Someone just tried to sign in to your Google Account ***** from an app that doesn't meet modern security standards.

We strongly recommend that you use a secure app, like Gmail, to access your account. All apps made by Google meet these security standards. Using a less secure app, on the other hand, could leave your account vulnerable. Learn more.

Google stopped this sign-in attempt, but you should review your recently used devices:

theres a copy of the email text that i was sent.. i think that u can still disable this in your gmail preferences.

the fix for this is to visit this url, while signed into your gmail account:
and select "turn on" to enable access by "less secure apps"
