I'm running Office 2007 (yes, I know!) - including Outlook - on my W10-64 Pro desktop.
If, immediately after a re-boot and before running Outlook, I look at the timestamp on my .PST files (Outlook and Archive), I find that they're showing the *current* date and time rather than the time when Outlook last closed down and saved them.
This is a major annoyance because, when I go away for a few days, I copy the files onto my laptop, and when I return I copy them back using Robocopy - which I've told only to copy later files.
But, because files on the desktop are showing the current time, it doesn't copy them.
Any ideas as to what process may be updating Outlook's files when Outlook isn't running?
