Cross forest AD migration by retaining same exchange 2016 domain (email address)

Copper Contributor

I have a scenario where I have to migrate AD forest with an exchange server. However the exchange server SMTP address should not be changed and same email address needs to be retained for all users. 

I have setup cross forest migration for users and computers with ADMT. Exchange mailflow is also configured and working between source and target exchange (i created a custom accepted domain for source and target and set external email address). However I have a doubt how the Autodiscover works especially for the external users (mobile devices and not domain joined devices).

 

Can anyone advise how to configure auto-discovery for internal and external users in this scenario? 

 

Example:

Source AD Forest : abc.com

Source email domain : abc.com

 

Target AD FOREST: xyz.com

Target email domain: abc.com
