We are experiencing a "Search Folder Poltergeist" here. It only happens with two user's mailbox, and the symptoms are:

1. One creats a search folder using whatever method (Find by example).

2. At the end of the Assistant, you press Finish to save your search folder.

3. For one second the folder appears on the tree, but after that short time, disappears.

4. If you try to create the folder when positioned on the Mailbox, sometimes you get error D107 ????

I did contents maintenance of this mailbox, even using DelDupFolders option, and no luck at all.

Anybody seen this before?

Thanks a lot in advance,

Xavier Serra
