We are in a hybrid environment &nbsp;where we have SBS2003 and Office365 hosted service. &nbsp; The premise hosted exchange is used only for internal communication and the hosted service mailboxes are for external communication. &nbsp; &nbsp; We are investigating to see if we can move the internal mailboxes to the external service (O365 hosted) and limit their ability to communicate only to specified domain or group. &nbsp; Would like to discuss this scenario as we are planning to upgrade our workstations and found out that Outlook 2013 won't work with SBS2003 Exchange server. &nbsp; &nbsp;Thanks.

This includes the development of professional skills, creating work processes, and almost any program used to create or modify a document, image, audio or video clip. However, business application suites such as Microsoft Office, which include word processing, spreadsheet and presentation programs, are typically called productivity software, as contrasted with a "utility program," such as a file manager, which is used to organize files and folders on the computer. Many office- and business-oriented groups of programs are organized into suites.
