Certificate for OA
Hi Guys,
I am about to purchase certificates for outlook anywhere but i am a bit confused.
Basically, we got 2 exchange 2010 servers located in different sites and both are in the same domain.
Now my question is, will a wild-card certificate work for my 2 exchange servers or do i need to purchase a certificate per server?

I wouldn't recommend using a wild card, although technically it works it is sensibly harder to configure specially if you are not experienced
I would buy a SAN certificate and include all the needed URI in it

will it work if i install 2 certificates, one on each server ?
because is cheaper rather than buying a SAN or Wild-Card Cert.

no it won't you do need a SAN certificate (or a wild card)
san certificates are less than $100 a year

Yes that worked
A wildcard certificate will work fine, unless you have older Windows mobile devices or you have OCS2007 and need integration. If you have Windows XP clients that aren't at the latest service pack level, you also need to make some changes to the certprincipalname so that is uses msstd:*.yourdomain.com
If you choose to purchase a SAN certificate, you need at least mail.domain.com and autodiscover.domain.com, provided only one of your sites is internet facing. If both sites are internet facing, you will need a third name on the cert for the second site.
