Many times, the enterprise Exchange server uses MAPI or Exchange Server cache mode to communicate with the client's Outlook, then by default, the piece is stored in the following location: Documents And Settingsuser nameLocal SettingsApplication DataMicrosoftOutlook. As the usage time goes on, the file will continue to increase, taking up a lot of C partition disk space; however, when using Outlook 2013 to create a new Email account, its data file (.ost file) is always saved in the C disk default directory. This takes up space on the C drive. Entering Outlook by default, I found that the location of the .ost file in the setup options seems to be unchangeable! In view of this, we provide a way to change the path of the data file in order to free up the disk space of the C partition.
