I've routinely exported my Outlook calendar as a .pst file.

If you're using a POP account, your data already is in a PST. Never export to
a PST. You'll lose data It is not an exact copy of your existing data file.
Just close Outlook and use Windows Explorer to copy the data file.

Today I'm getting an error Cannot add Outlook-specific information to the
store.

Is that the exact and complete text of the error? To which data store does it
refer, the original one or the copy you made?
