Outlook server certificate error

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.

you can't change it.. it is a certificate problem at their end. outlook.com uses Microsoft exchange.. do you have owa access as well now?

you might want to check it with http://testexchangeconnectivity.com/  and check its diagnosis

Hi  ve3ofa, thanks for the feedback.

Not sure I understand though, these are simple standalone PC's using Outlook 2007 to connect to the ISP mail servers (BT)

I know the upgrade involves using Microsoft 365 now, does that mean we are litterally using BT's Exchange servers to collect emails now ?

The Tech Support at BT seemed to be saying problem was at our end (although happens on all the PC's)

I'm a bit perplexed at why no-one else has this issue, given that BT must be migrating 1000's of email accounts per week to this new system.

Sorry for the lack of knowledge, but we dont even have a server, never mind an Exchange server. Thanks for any more pointers, appreciate your help thus far.

no you are using office 365 with BT acting as the partner.

your settings SHOULD be like this and not just outlook.com. the podNNNNN will change these are mine

POP setting
Server name: pod51010.outlook.com
Port: 995
Encryption method: SSL

IMAP setting
Server name: pod51010.outlook.com
Port: 993
Encryption method: SSL

SMTP setting
Server name: pod51010.outlook.com
Port: 587
Encryption method: TLS

try logging into office365.com using your username and password .. if you can login then use these instructions to set up your mail clients
