I renewed our SBS 2008 Exchange certificate last week. It is the self signed one created by the server when we first set it up (2 years ago).

Since doing this one user (Outlook 2010) gets the message "The name on the security certificate is invalid or does not match the name of the site" when he opens Outlook.

Interestingly none of my other Outlook 2010 and earlier users get any messages at all - just one user.

Can anyone advise what I need to do in order to stop the message coming up each time Outlook loads?

If he clicks ok it opens Outlook fine.

You probably have to import the certificate on the machine this user is using. Does the user get the same error when using a different machine?

I've tried a couple of things so far:

1. Installed the certificate via Internet Explorer

2. Changed the AutoDiscoverServiceInternalUri setting (via forum help)

Neither of the above fixed the problem.


When you say import the certificate, do you mean import via internet explorer - Content - Certificates? Is this not the same as Installing the certificate?

It should be the same. you can check by typing MMC from RUN and then adding the local computer certificate snap-in and make sure the certificate is actually in there.

Tried that already. It's actually affecting three users in total - two on Outlook 2010 and one on Outlook 2007.

I've seen some commands that can be run via power shell but I'm sure there must be a way of fixing this via the workstations. Seems a bit OTT to be making changes through power shell for just three workstations.

EXACTLY! If this issue is affecting a small set of users then it is not a server issue and you do not need to make changes on the server. You still have not responded to my question on whether the same users experience the same behaviour when they log onto other (working) workstations!

Yes it occurs if he logs on to another computer that is running Outlook 2010 or 2007.

Basically any computer that runs Outlook 2007 or 2010 gets this message when Outlook loads
