Is there an app or is there a native way to assign tasks to users on an exchange server? Please let me know if this a feature of Blackberry's internal Outlook/Exchange software.
I have an iPhone at the moment, but there is no way to assign tasks.
Try posting this in the business / enterprise (BES) fourm... perhaps some of the corporate / BES users would have a better insight... I don't think it's possible over regular BIS, other then sending meeting requests (calendar), which could be one method to assign tasks to users via email, however i believe the iPhone can do this as well...
