SYMPTOMS

Exchange 16-bit Windows client, the following error can occur:
The logon attempt timed out while waiting for resources to become available
Mapi 1.0 [00000a02]
WORKAROUND
==========
- Open Control Panel and select the Mail And Fax icon. Click Show Profiles,
then click Properties. Then, without logging on, double-click the Microsoft
Exchange icon to bring up the Choose Profile dialog box.
-or-
- Complete the logon process held by the Choose Profile dialog box.
-or-
- Cancel the Choose Profile dialog box to free the logon mutex.
STATUS
======
Microsoft has confirmed this to be a problem in the Microsoft Exchange version
4.0 16-bit Windows client.
MORE INFORMATION
================
The error message occurs because of the action that selecting the Delivery tab
employs. "Delivery" is trying to log on while a logon mutex is held. A mutex is
a type of lock that prohibits other threads from attempting to execute the same
process. In the reverse case, the logon is completed before you attempt to do a
second logon so no error is generated.
