Hi I have active directory and two accepted domain in exchange I need creat same user with different mail for example:I have one user test@list.com I want creat same user but I need change domain for example: test@bk.com Can I creat same logon user in active directory?

HI,

In active directory you can not create 2 users with the same logon name. It wont accept.If you have two AD domains then you can.

As you mentioned you have 2 exchange domains, still it will get the AD use details from the AD domain which I believe a single domain.

thank you

Hi,

The limitation is that when the account sends an email it can only ever send using the address set as the default reply, if you need to send as both addresses then you need to create multiple email accounts and setup forwarding and send as permissions on one of them.

And also you could check the thread for a reference.
