when a user is modified with native Exchange tools, Exchange updates his e-mail addresses according to address policy. For example, when policy says that e-mail address is firstname.lastname@company.com, and the user is renamed from Peter Oldname to Peter Newname, Exchange adds a new SMTP address peter.newname@company.com and makes the old address peter.oldname@company.com a secondary one.

This process is not triggered when we modify a user with ADManager. Though the option "Automatically update e-mail addresses based on recipient policy" is checked, this does never happen. 

This causes a lot of additional work and is a cause of failures. Is there any chance to fix this?
