  • Microsoft Mail for PC Networks 3.0

This article was previously published under Q101554


In version 3.0 of Microsoft Mail for PC Networks, Macintosh workstation, you may receive the following error message when trying to access the Microsoft Mail Notifier Control Panel device (cdev):

The control panel "Microsoft Mail Notifier" cannot be used with this Macintosh.

After adding the Notifier to the Macintosh's System Folder and restarting (rebooting) the computer, the icon for the Notifier is crossed out (it appears as an envelope with an "X" through it). This indicates that the Notifier Control Panel device did not load.


The above error message is incorrect. The Notifier can work with any Macintosh computer.

To correct this problem, do the following:

  1. Log on to Mail.

NOTE: Mail may prompt you to locate the postoffice before login can be completed.

  1. From the File menu, choose Set Preferences.
  2. In the Misc Options section, retype the default login name in a different case; for example, replace JohnDoe with johndoe. If you change one character, the problem is corrected.
  3. Choose the OK button.

NOTE: You may see the login name go back to its original case. That is OK. Continue with steps 5 and 6.

  1. Quit Mail.
  2. Restart the computer. The Notifier icon, without the "X," should appear when you restart (reboot) the computer.

NOTE: If the Control Panel icon for the Notifier appears as a blank page instead of the dog, rebuild the desktop by pressing COMMAND+OPTION while rebooting the computer.

NOTE: If the above steps do not work and you have 32-bit addressing on, do the following:

  1. Turn off 32-bit addressing.
  2. Follow the steps above.
  3. Confirm that the Notifier works.
  4. Turn back on the 32-bit addressing.

NOTE: If the above two procedures do not work, do the following:

The AppleShare volume where the Microsoft Mail for PC Networks postoffice is located must also be mounted at startup. This share is where the PC postoffice resides--on a PC file server running Macintosh services.

The Microsoft Mail Notifier Control Panel device must be able to verify the username in the Mail Preferences dialog at startup time. This means the postoffice, on the AppleShare volume, must be available so that the Notifier can access the local user files on the postoffice, the ACCESS*.GLB files. If this check fails, the Notifier will not load.


Microsoft has confirmed this to be problem in version 3.0 of Microsoft Mail for PC Networks, Macintosh workstation. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
