Hey
We are investigating the possibilities of using IPv6 in combination with Microsoft Exchange Online and have a few questions about this.
Is it possible to enable IPv6 online in Microsoft Exchange and how do we this?
What is the method to let a Windows client communicate with Microsoft Exchange online via IPv6?
Are there other things to watch out for?
Thanks in advance!
