[Outlook] Pop-up de sécurité intempestif...

Question

Hello!

So, I have a little issue with Outlook 2003, nothing too serious but it is a bit of a pain... Every time I open the software, a window titled "Internet Security Warning" pops up. It says the following message:

"The server you are connected to is using a security certificate that cannot be verified. A certificate chain has been processed but ended with a certificate root that is not trusted by the approval provider. Do you want to continue using this server?"

And then I have to click "Yes" to receive my emails.

This problem is even more intriguing to me since several people with exactly the same computer, the same operating system, and the same settings as I have, have never encountered it, while I've been facing it since my very first use of Outlook...

Well, I hope someone can help me!
Thanks in advance.

Hi everyone!

If others have the same issue, I’m going to tell you what I did.
I suppose many actions don’t help but I don't dare touch anything now that it’s working.

First, go here:
Back up your registry by using File > Export in the registry
then follow these instructions: https://docs.microsoft.com/fr-fr/outlook/troubleshoot/security/how-to-turn-off-email-matching-for-certificates

Then, if your problem is the same as mine, it shouldn’t change anything but you need to go to Outlook > Tools > Account Settings, double-click on your account, make sure the POP3 and SMTP settings are configured correctly, then go to More Settings in the Advanced tab and click on Default. Personally, being with Club-internet, I had to uncheck SSL verification and set 110 for the POP3 server and 25 for the SMTP.

The Default button fixed it for me on its own.

Do the same with all your other accounts.
It should work.

Good evening
Go back to advanced settings, then in the advanced options tab, uncheck the box for SSL and set the parameter titled Use the following encrypted connection type to None.

See screenshot if your version of Outlook is different:

These settings work for Outlook 2007 and Club-internet.
See you soon

Hello
I also just had this problem regarding the window telling us that the certificate is no longer valid. I tried the methods mentioned above, but it didn’t work. I found a very simple solution (it worked for me): you just need to delete your email account or accounts and set them up again, and it works. I think that by recreating it, it automatically retrieves a certificate by itself!
See you soon

I found it, if at the beginning when you added a new email account you chose IMAP instead of POP (like me) the only thing you need to change is your incoming mail address to: imap.gmail.com instead of pop.gmail.com

there you go, magic, magic :)

Hello everyone,

I had the same issue with OUTLOOK 2007, this infamous window "The server you are connected to is using a security certificate etc...." and I resolved the problem by downloading and installing the OFFICE update here => https://www.microsoft.com/en-us/download/details.aspx?id=27838

I hope this helps you solve yours.

Good luck

I had the same problem, and when I reviewed the configuration of my email boxes, I saw that one of them was configured as: pop3.neuf.fr
so I removed the 3 and configured: pop.neuf.fr and everything seems to be working well.
