Hi,

I have 4  mailbox servers and 4 CAS servers. I need to implement Edge role with 4 mailbox servers. Also I need to have more than 1 edge role for High Availability. How is it possible?

Can anyone help me.

Regards,

Anees

Hi Anees,

Thank you for your question.

I agree with Sneff.

In addition, you could install multiple Edge servers and use NLB for high availability:
