Office 365: Outlook & other MSO apps interaction
A curiosity, perhaps a setting somewhere, perhaps intentional by design.
I use Outlook client for my emails using outlook.pst for emails to my main email address, other .pst files for my other email addresses.
Assuming Outlook is not running, I've noticed that when I open another Office app, Word, Excel, PowerPoint, Publisher for example, a file ~outlook.pst.tmp is created, even if no document is opened. When I close the Office app that file is closed and disappears, and the modified date and time for outlook.pst is updated to reflect the time of app closure.
I can sort of understand it if I'd opened an Office document, especially one that had email links, but opening the .tmp file when purely opening the app seems perhaps odd.
Anyone know the reason for this?
