2 Exchange Organizations in 1 AD forest ? 2016 with 2019 separate orgs in 1 AD Forest
Hello All,
is it Technically possible to have 2 Exchange Organizations in 1 AD forest ?
For example, My current environment is running, Exchange 2016 with Server 2016 and AD Forest Functional Level 2016. 1 AD Forest, 3 Sites.
Assuming, I want to have my environment be upgraded to 2019, with or without a coexistence of 2016 + 2019, if i want to have an Additional Exchange Organization within my corp network of 1 AD Forest, is it technically possible .?
I cant seem to find any relevant or official documentation in this regards.
Anyone who has any experience with this if possible, please shed some light on this.

Unfortunately it is not possible to have two Exchange Organizations in the same forest. It is also not possible to have a new Organization in a forest with a child domain or tree domain.
To have a new Exchange Organization it is necessary to have a new Domain on a new forest.
On the other hand, it is possible to make a trust between these two domains.
