## SYMPTOMS

When you run the Microsoft Mail Administrator program (ADMIN.EXE) and you select Admin, Folder, Compress to compress folders, the following error message may appear:
Notice 158 : Folder in use, they were not compressed.
Run Foldcomp -s if this persists.

## CAUSE

This problem is caused by a semaphore lock on a folder file.

## RESOLUTION

The folder that remains on the screen when the Mail Administrator program displays the Notice 158 error is not necessarily the subdirectory in which the FOLDCOMP -S command needs to be performed.
If the error persists after you run FOLDCOMP -S on the subdirectory displayed, run the FOLDCOMP -S command on all folder subdirectories.
