Exchange 2010 SSL Certificate Issue?

Sir,

WE installed exchange 2010 server and external owa url is worked  but we type the full owa url as per the https://mail.lexgyan.com/owa .

It shows the IE certificate error bar.But that certificate when we installed in IE in the trusted root cert Auth, that certificate is showing installed in IE but when we search in IE that certificate is not finding.

when we export from the other browser and installed in IE. It show Red bar in IE browser

Because of this certificate we can't installed the outlook account on desktops.
Here we attached the file for the reference.

1)we need the certificate is valid and how to validate for external users to configure their outlook accounts.

I don't think that the Outlook connection error is caused by the certificate. Correct me if i'm wrong please. Maybe this helps?

For owa do you have the correct URL added to the certificate?
Another possible could be that you have RPC encryption enabled on exchange 2010 which by default is not used in outlook 2003.

http://support.microsoft.com/kb/2006508

Another thing to consider is your outlook 2003 clients need to be at least at SP3 to work with Exchange 2010.

Alot of issues still exist with Outlook 2003 clients and exchange 2010 unless you upgrade Exchange 2010 to At least SP1.

To sort out the certificate
Is this a certificate issued by a domain joined CA?
If it is domain joined are these clients in the same domain?
If the CA and machines are in the same Domain this certificate should be explicitly trusted already. If its not then this indicates a bigger domain issue, such as group policy not applying. (From the looks of it this is the case). If you just want to resolve the CA issue then
1) Download the CA chain from the CA.
2) Open an MMC
3) file -> add/remove snapin
4) Certificates
5) Computer Account
6) Local Computer
7) Finish
8) oK
9) Expand Certificates(Local Computer)
10) Right click Trusted Root Certification Authorities
11) Select Import and choose the Chain you downloaded earlier

If the CA is however not in the same domain then you need to follow the above steps.
Purchase certificate or SAN certifcate from the third party vendor like go daddy, digicert.com.

To  validate for external users to configure their outlook accounts.

This certificate issue by your own CA and it is not recognize by world wide so it show red mark. If you want to keep it this certificate with red mark just install this certificate in certificate on your local computers.

OR

Try the third party (like go daddy, digicert.com.) certificate to remove red mark from your ssl certificate.
As stated in my previous comment

The error with downloading mail indicates that it could not connect to exchange. This can be due to a number of reasons. Connectivity, incorrect details, incorrect publishing, etc.
