Your Outlook Data file (.PST) is saved automatically every time you close Outlook. The default location of the Data file C:\Users\[UserName]\Outlook. If you create any Personal Folders in Outlook to save your Emails, they will create additional .pst files. Introduction to Outlook Data Files (.pst and .ost) Any backup program that backs up your User files, also backs up the .pst files automatically.I open Outlook app when I log on each morning and I close it when I'm logging off. This locks the PST file, so it would never get backed up.
Thanks spunk.funk. Post #20 above suggests that "open" files can be copied, so I'm now confused.You cannot backup any file that is open, If you had Adobe Acrobat open, you couldn't backup that PDF files. Same with Outlook, and the same with Shadow Copy, just close all programs before backing up,
Thanks for the clarification spunk.funk. That's very handy to know.A .pst file is not like an open .Txt file or .pdf, When Outlook is open, it locks the .pdf because new Emails are coming in or being sent. Copying a .pst file while Outlook is open can corrupt the data at it's worst and you will have incomplete data at best. this can be avoided if you just close Outlook while copying and use OWA for Email until the copy process has completed. Can copying a .PST file while outlook is open corrupt said PST.
