 Last reviewed: October 31, 1994
Article ID: Q101814
The information in this article applies to:
  • Microsoft Mail for Windows, versions 3.0, 3.0b, and 3.2

SYMPTOMS

Some peer-to-peer networks may have difficulty locking files in versions 3.0 and 3.2 of Microsoft Mail for Windows. Common error messages caused by insufficient file locks are: 

   Your message file could not be opened. To access your message file
   in its current location, mail requires that the MS-DOS utility
   SHARE.EXE be run before Windows is started.
-or- 

   You do not have the proper access to the postoffice. Please contact
   your system administrator.
-or- 

   Another machine is already signed in with the user name you have
   entered. Sign out from the other machine and try again.

CAUSE

Some possible causes of the above errors are as follows:

  • Allocated file space for SHARE.EXE is insufficient.
  • The number of files that can be locked at one time is insufficient.

RESOLUTION

To remedy this problem, load SHARE.EXE on the server storing the postoffice with the following command-line options: 

   share /F:16384 /L:255
For more information on SHARE.EXE, see your Microsoft MS-DOS documentation.
