Good afternoon everyone, Since our internal domain is .local based and certificate is assigned to mail.domain.local, we get warning and click "YES" on OWA which is fine. But this stops rpc/http work so I am wondering if it is going to cause problem for OMA/https. Can I use https for oma in this scenario or have to go with http?
