Unable to read inbox.

Mail starts and you can open your inbox, but none of your messages appear in it. You can also compose a new message, but when you attempt to send it, the following error appears:

Unable to transmit message. Try again. If the problem persists, check if the server volume is still mounted. Otherwise, contact your administrator."



CAUSE
You do not have the Make Changes MacFile permission set for the workgroup postoffice Macintosh-accessible volume.



RESOLUTION
Use the File Manager MacFile menu on the Windows NT server to give all Macintosh Mail users accessing the postoffice See Files, See Folders, and Make Changes permissions to the workgroup postoffice root directory (WGPO by default) and all of its subdirectories and files.
