"Cannot display the folder. There is not enough free memory to run this
program. Quit one or more programs, and then try again."

As you might guess, there are ample resources available and all other
applications work and behave as expected (without warnings/errors).

The issue is very likely a red herring, but looking to get feedback as to if
this is a corruption issue in a PST/OST (we are running Outlook in cached
exchange mode).

Outlook is at SP1 level

This error was in the PST, but then I saw that same error when looking at
the list of to-do items, so its may have an indirect effect on the OST?!?!

Once the user sees this error, it will apply to almost all folders (with the
exception of the inbox (which is in the OST). I have had the user reboot and
the problem has gone away…

Any thoughts, suggestions, comments?
