Why does Outlook constantly modify Archived PST files
Posted on 2014-03-24
I use Microsoft Outlook 2007 on Windows 7, and each year I archive the previous years emails into an archive PST
I have been doing this a while, currently I have my "current" PST file (named 2014) and then a bunch of connected PST files named 2013, 2012, 2011 etc (about 8 in total)
I have recently subscribed to an online backup service (Crashplan) and have selected that I want my PST files backed up.
However these PST files seem to constantly be accessed/modified. If I look at them in Explorer, the "Date modified" is always the current date and time. Even Archived PST files which I wouldn't have even looked at for 6 or 7 years will have been "modified" this very minute.
So every time Crashplan does a backup, it thinks it needs to upload these 8 or so PST files as they have changed (at 3-4 GB each) so it is really slowing things down.
I wondered why these files are being accessed. What is Outlook doing to these files constantly? And is there anything I can do to stop it? Apart from detaching them from my Outlook account I cant think of anything else to do.
Thanks a lot
