Hello, I have a big problem in our company. In my company domain environment I have Domain Controller, Exchange Server...etc. Here's my question. We are going to buy another company, Currently our Exchange server is running in good condition. Also Certificate working fine. My current Certificate is *.mycompanyname.com  It's a Wild Card Certificate. The new company runs Zimbra Server for emails and they have a domain named therecompany.lk  .  The 2 Certificate we have various. so i need to know how can i add 2 various domain to my Exchange server. What is the Solution for me? Please help me.

Regards,

Hi Ashane -

You will have to purchase a new certificate that will not be a wildcard certificate. You can purchase what is called a SAN certificate (Subject Alternative Name) which allows you to add additional names to your cert.

In Exchange, you can go through the certificate creation wizard and add these names to create the certificate request and then go purchase a public certificate from a reputable source.

Thanks,

Jason

Hello Jason, Thanks for replying my question. Here's my next question. I have a domain calls ABC.com. Currently Wild Card is configured for *.ABC.com . If i have another domain calls DEF.net . How can i add for the SAN Certificate these 2 domains? I need to add these 2 domains for the exchange server because the DEF.net domain is in another company. If i purchase SAN Cert i have to add abc.com, autodiscover.abc.com, mail.abc.com, abc.local . how to add the DEF.net domain names to 1 SAN Cert?

Regards,

Hi Ashane,

Thank you for your question.

If we want to merge two companies into a company, we could migrate .lk user account to .com and only use .com certificate.

If we want to two companies which are co-existed. We could keep the certificate for themselves, then we could create accept domain on Exchange server. we could also deploy Exchange server on .lk domain using .lk certificate.

If there are any questions regarding this issue, please be free to let me know. 

Best Regard,

Hi Ashane,

I am sorry that we could not do it. We could not add autodiscover.abc.com, mail.abc.com, abc.com, autodiscover.def.net, mail.def.net, def.net . all these 6 addresses to 1 SAN Cert
