Our Mail SSL certificate is up for renewal. It's a UCC for up to 5 domain names. This includes the internal & external domain names.
Our internal domain name is (domain-name).local
Apparently all the SSL providers around the world are no longer supporting *.local names, so as a result, our internal users are going to be prompted with errors in MS Outlook all the time about the SSL being out of date.
Does this mean we have to change our Internal domain name before we can re-renew the UCC SSL Certificate?
Obviously that would be opening up the biggest can of worms, so would prefer to look at workarounds. This internal domain will be decommissioned within the next 12 months (merging into another companies domain). So if there is a workaround, that would be the best option for us.
