Brian, I was able to locate the file in AppData by opting to see hidden
files
and when I save the .pst file, it was about 1009 KB. However, when I added
a
lot of data to the calendar, the .pst file size stayed the same - i.e. it
doesn't seem to be saving the additional data. Yet, when I look at the
calendar file size by clicking on the Personal Folders, Outlook Today bar,
the calendar file size has increased. Why doesn't the size of the .pst file
increase. It appears to the novice, like myself, that the new data is not
being saved in the .pst file. What's going on?

The PST is a database. Databases, over time, accumulate what's called "white
space". This is space taken by records that have been deleted. The unused
space remains in the file and available for reuse. it is not returned to the
file system except under specific conditions. If you add items to one of
Outlook's folders but the PST doesn't grow, then it;s likely you're reusing
white space.
