Unfortunately, when importing throws an error, opening the PST file usually does too. The problem usually arises from the way the PST file was created or transported. That's why I requested the steps that created the problem in the first place. Should be simple to figure out after that. Users who import are often ones who first exported, and exporting can corrupt the PST file.Russ Valentine
