2 Exchange Organizations in 1 AD forest ?

Iron Contributor

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.
