General Trivia: Outlook and its Data Files

Many users are aware of Outlook mailing client. The mailing client provides users with a facility of mailing and helps in maintaining folders like address books, calendars, notes, journals, etc. MS Outlook saves all the data of a profile in data files.

While the entire process is done, in such case, all the mails and work connected to Server can be configured with MS Outlook.
