Will Exchange 2016 fix the mailbox Automapping feature when a security group is used to apply full mailbox permissions instead of individuals?

As of now, mailbox automapping only works with Exchange 2010 SP1 or later and Exchange 2013 if full mailbox permissions are applied to individual mailboxes not security groups.

I don't see that yet with Exchange 2016 Preview....

Automapping is populating the msExchDelegateListLink attribute of the AD when someone gets access to the mailbox, I guess Exchange doesn't have logic (yet) to expand the membership of the group and add the members DN in to this attribu

Hi Jcollotzi,

Moreover, I have seen people using this as a cherished workaround for disabling Automapping in

Hi Jcollotzl,

Thank you for your question.                                         

At present, there is no official document which is about mailbox auto-map on Exchange 2016, please wait for Microsoft update.

If there are any questions regarding this issue, please be free to let me know.

Best Regard,

Jim
