Outlook 2013 backup
When the email box is filling up the following gives you the fastest way to create an archive or backup the emails.
Turn on Cached Exchange Mode - if it is not already on - and drag the slider to All. Now all your email on the Exchange server is copied to the local computer and can be backed up. For instructions, click here.
Wait until the Outlook status bar at the bottom of the window says "All folders are up to date". Now you can begin to create a backup, as follows.
Export to file:
Outlook data file (.pst):
Either select the whole mailbox or select separate folders to be backup up:
Select a folder to save the backup to. Do not save the backup file directly to a network drive. Save the backup file to the local computer. After that you can copy the backup file to a network drive such as your home drive:
You can set a password.
Monitor the copy process. If your mailbox is very large (several giga bytes), copying may take dozens of minutes. During this time Outlook cannot be used:
Remember to create a backup copy of the .pst file to Z drive, your home drive. Close Outlook before making the copy! Never open the .pst file in Outlook directly from a network drive. Only keep a backup copy on the network drive:
Set the Cached Exchange Mode slider backup to 12 months. For instructions, click here.
Do not edit the archive contents by deleting or editing the messages. By doing so you might endanger backup file integrity. Also, do not open in Outlook a backup file that is located on a network drive. Copy the file first to the workstation and then open that copy in Outlook.
