OWA stopped working for remote users

After couple restarts Mail server with  Exchange 2007 started having issues with OWA with NTLM authentication.  Internally all users can connect to it within Outlook. Externally Outlook complains about certificate. First error I have seen was code 2. When I removed already installed  certificate that was on computer I was using Outlook and re-add it then error code 8 appears saying the Certificate is invalid. There were no changes to any of the certificates and only one certificate is installed on the mail server.
I have involved Microsoft but so far no luck with them.
Server is Windows 2003 R2 and Exchange 2007 SP3 Rollup 12.

Are you using a trusted certificate or a self signed certificate?
If a trusted certificate get the SSL provider to reissue it. It could be corrupt. Most providers will do a rekey for free.

Its self signed certificate.

You should really be using a commercial certificate. When you can get a compatible one for less than $80/year, it doesn't really make sense to use self signed.

You could try running new-exchangecertificate from EMS and then enabling the new certificate for the services. However I would encourage you to switch to a trusted certificate.

That's what I was thinking. Not sure though if that would resolve it.

I have reissued self signed certificate and seems external side start working. I will buy SSL certificate for this for future. You are right less headache.
