We are also looking for a way to either message or email a pool of users automatically using Power CLI or some other way. We have tried to email the users and the only way that we have found that this works is to export the username from VIEW and copy it into Outlook. Then we do a Check Name in Outlook. Having nearly 40,000 employees it is not an easy task because there are many similar users in the address book.
Is there another way that this can be done? Any other 3rd party software that will do it? Thanks!
