BlackBerry devices can use an application known as AstraSync to interact fully with OIT's Exchange service. With Exchange configured, you will be able to view the account's various mailboxes, and create custom mailboxes. AstraSync allows for users to use their Exchange e-mail as well as their Exchange calendar. Without this application the Exchange calendar will not be able to be viewed or used. However, e-mail is able to be accessed without AstraSync by using the settings located on the IMAP connections settings page.
Requirement: AstraSync Application
