If you delete one dist list can you create another one (as a test)? Also,
it's a long shot but try running ScanPST.EXE on your PST file to see if it's
damaged.

One more thing... what's the size of your PST file?

THanks, Vince.
I just the one contacts folder. However, I do have multiple distribution
lists made up of various combinations of those addresses. Including the
entries in each distribution list, there would still be fewer than 800
entries.
