SUMMARY
 
Users can have access to the same Mail message file (.MMF) from more
than one computer. To do this, the user's message file is stored on
the postoffice server instead of the local computer.
NOTE: Mail message files on the postoffice server may take a very
large amount of disk space; make sure that the server has an adequate
amount of hard disk space before storing message files on it.
MORE INFORMATION
 
To access the same message file from more than one computer, do the
following:
- Open Mail on the first computer and from the Mail menu, choose
   Options. Then choose Server and select Post Office as the Storage
   location.
- On this same computer, choose Address Book from the Mail menu, and
   make note of the name of the Mailbox for this user by choosing
   Details.
- The message file for this user will be automatically moved to the
   WGPO\MMF subdirectory on the Postoffice server and renamed to
   00000001.MMF or a similarly incremented number.
- Exit and sign out of Mail on this computer.
- Open Mail on a second computer, choose Connect to an existing
   postoffice and point to the correct \\SERVER\WGPO where the postoffice
   server is located.
   NOTE: If an account has already been established at the second
   computer, it will be necessary to recreate the Mail initialization
   procedure before doing this step. For information on how to do this,
   query on the following words in the Microsoft Knowledge Base:
 
       recreate and postoffice
 
- When you are prompted on if you have an account, choose Yes and
   enter the existing Mailbox name and password that is being used on the
   first computer.
 
Both computers can now use the same message file, which is stored on
the server. This procedure can also be used on other computers.
NOTE: Mail cannot be open on two computers at the same time.
