It is recommended that your PST file is saved to the local hard drive. Saving your PST to a network drive can cause issues with the performance of Outlook. Create the pst in a folder called 'Outlook files' within your Documents folder and then back up the PST to a network location. The backup process can be automated using a program called SafePST which can be installed via the Software Centre.
The instructions below can be used to either create a personal mailbox PST file or shared mailbox PST file.
We do not recommend allowing the PST file to exceed 2GB. If the file is going to exceed this then we recommend creating a new PST file.
For step by step instructions for setting up a backup process for your pst file see the page How do I use SafePST?
