Windows 10: Windows 10 MAIL APP on my laptop complains about server certificate

Today my laptop's Window Mail APP has decided NOT to send any emails because it thinks the server certificate is no good. It will RECEIVE email however. The 'settings' for the account are extremely limited, so there really isn't anything that I can change about those. The email account is a POP3 account and is working on my iPad and my Windows Desktop Outlook.Any idea how to get around this? It's a weekend and can't connect with the email server people.ThanksBarb

Mail app will not open on 10041.

Hello Adam,

This is the suggested solution below if you haven't already tried it.

In this Windows 10 build 10041, the Mail, Calendar, and People apps may be broken due to a licensing issue with the Store Beta. To get these apps working again, you need to follow these steps:

• Open powershell as administrator
• Run the command Get-appxprovisionedpackage –online | where-object {$_.packagename –like “*windowscommunicationsapps*”} | remove-appxprovisionedpackage –online
• Re-install Mail, People and Calendar from the Store (green tile)

 

Windows 10 Mail certificate errors

Hi community!

I'm using the Windows 10 Mail app with my personal IMAP-server using SSL, using an internal corporate CA Certificate (SHA256, trusted as Root CA by the clients), and a wildcard-certificate on my connection (also SHA256, mydomain.com and *.mydomain.com).

This formula worked like a charm for the Windows 8.1 Mail app, and still works perfect in Outlook 2013. Also Edge, Chrome and IE trust the wildcard-certificate perfectly without issues.

Only the Windows 10 Mail app complains that the certificate for imap.mydomain.com is invalid and refuses to collect or send my mail. I can push the button to collect mail anyhow, but the error keeps recurring and the app won't send any mail.



Translation from Dutch dialog:

Untrusted certificate.

The certificate for imap.mydomain.com is invalid.

This can indicate an attempt to gain access to or theft of your data.

It's not recommended to connect to this server.

Do you want to connect anyway?

I once got the error code 0x80072f89 to appear, but can't really recreate that, so I'm not too sure this actually was 100% related.

Can anyone tell me how to fix this? Or how to debug the reason for certificate denial. Or point me into the direction to find what specific requirements exist for imap/smtp-certificates for Windows 10 Mail?

Thanks!

Hey Shawn,
I did that to no avail, then I ran WSReset.exe; now I'm good on all 3, Mail, Calendar and People! *Confused
Go figure!
