Using Outlook Personal Folder (PST) Files

Each faculty and staff member has an allotted storage space (quota), on the Exchange e-mail server to store your Towson mailbox that includes e-mail, contacts, calendar, tasks, etc. If you need more storage space than the allotted quota, an option is to move e-mail you wish to save to your Personal Storage (PST) files. The H: drive is secure and files are backed up on a regular schedule to prevent data loss.

Once you add the PST file in Outlook, it appears as a new personal folder in the Outlook Navigation Pane, below your other folders. Each PST file can contain subfolders to make filing e-mail messages easy. Within Outlook you drag and drop messages from your mailbox to the appropriate PST folder (stored on H: drive). To access PST files from other computers or remote locations, use Virtual Workspace at:
