adding a security certificate to our website

we have a security certificate to cover our domain name, which we have added to our mail server.

however, we also have a website which is hosted by a third party, and it cannot be accessed using https://www.domainname.co.uk

can we use the same certificate that we use for our microsoft server to cover our website too, or do we need to purchase another one?

how do we add the certificate to our website?

if anyone can offer any guidance, we would be much obliged.

many thanks

if you use a wildcard certificate for your exchange then you're good to go.
Otherwise if you've got a multi domain cert (and most certs are of that type since the cost is similar to simple ssl certs) you can ask your CA emitter to add a SAN (subject alternative name) to the one you're using,

If you have a multi domain cert you can just add that name and install the certificate.

ask to their support: it's usually better than guessing :)
Edit: www.domainname.co.uk is different from domainname.co.uk

As Michelangelo suggested, first check with your hosting company.

Most hosting companies support simple integration of LetsEncrypt certs, because LE certs are free and can auto update, with no manual intervention.

Check about this option first.
