The status field in the file list of the Vault GUI client is designed to show the status of files in the local working directory as compared to the file in the repository. If you have no local copy, the status is Missing.

The pending change of your Vault GUI client tracks modifications or checkouts from your working directory that have not yet been committed to the repository
The Vault GUI client does not track the status of files in other users working directories. However, if a file is checked out by somebody else, a red checkmark should appear next to the file with the name of the person who has checked it out. This should happen whether or not you have a local copy.
If you are not seeing this, it's possible that you are using CVS mode of development, which means users do not need to check out files in order to modify them and commit them to the repository.
If you are using VSS mode, let us know if you are not seeing checkouts by other users in your Vault GUI client.
Source Control Status is not shown if no local copy
