Our company uses Microsoft outlook 2007 pop3 email, and the hosting supplier is BT (btconnect.com)
All worked well until we got a notification from BT to update our email client settings and they provided a "BT Businesses Broadband Desktop Tool" which would automatically review our settings and change required.
This process seemed to work fine and the emails still send & receive OK.
The issue is, everytime we start Outlook on any of the PCs, we get the following message:
"The server you are connected to is using a security certificate that cannot be verified - The Target Principle Name is Incorrect"
and prompts - "Do You Want To Continue"
If we click "Yes" , then all works well till next time we start Outlook when same message appears.
I checked some of the account settings in Outlook and they are now changed to:
Incoming Mail: pop3.outlook.com (used to be pop3.btconnect.com)
Outgoing mail: smtp.outlook.com (used to be smtp.btconnect.com)
in advanced settings, the POP3 port is now 995 and the SMTP port is now 587, and Encryption has now been enabled with "TLS" selected
I did a "live chat" with the BT technical and he said "he had never seen that issue" and told me all the systems at their end were working fine thus it must be a "software problem at my end" - well that narrowed it down a bit - LOL !
Any ideas would be most appreciated, I already "googled" the issue, but most replies are talking about Exchange and SBS certificates which doesn't apply to us.
