When creating a distribution group through ADManager Plus and selecting the check box to "Create an Exchange E-Mail Address", the address never gets created.

If I open up my Exchange manager console, I can see the that distribution group does get created but if I open up that group and go to the Email Address tab, there is no email address and it never gets genereated. I also notice that the check box for "Automatically update e-mail addresses based on e-mail address policy" is not selected. To generate an email addres I either have to manually add it or select the check box to Automatically update the e-mail addresses based on e-mail address policy.

Also, when adding additional email addresses for uses doesn't work because it does not deselect the check box for "Automatically update e-mail addressses based on e-mail address policy" so the policy forces it to only use the primary address

Lastly, there is no way to add additional email addresses to groups.
