A user did not accept a notification about an instant message on a computer and the notification disappeared
Possible cause
Applies to: BlackBerry Collaboration Service version 4.1 or later with the BlackBerry Client for use with Microsoft Office Live Communications Server 2005 or the BlackBerry Client for use with Microsoft Office Communications Server 2007.
A user logged in to Microsoft Office Communicator on a computer and on a BlackBerry device or on two computers.
If the user logged in to Microsoft Office Communicator on both a computer and a BlackBerry device or on two computers, the user received notifications about instant messages in both locations. The instant messaging conversation can occur only in the location where the user accepts the notification about an instant message.
If a user is logged in to Microsoft Office Communicator on both a computer and a BlackBerry device and the user does not accept a notification about an instant message on the computer before the notification disappears, the notification about the instant message disappears from the computer but remains on the BlackBerry device. If the user accepts the notification about the instant message on the computer, the notification about the instant message disappears from the BlackBerry device and the instant messaging conversation occurs on the computer. If the user accepts the notification about the instant message on the BlackBerry device, the notification about the instant message disappears from the computer and the instant messaging conversation occurs on the BlackBerry device.
During an instant messaging conversation, the user cannot switch between a computer and a BlackBerry device or between computers.
Possible solution
The user should look for notifications about instant messages on a BlackBerry device or on another computer where the user might also be logged in to Microsoft Office Communicator. If the user is logged in to Microsoft Office Communicator on a BlackBerry device or on a second computer, the user should only accept the notification about an instant message on the computer or BlackBerry device where the user wants to have the instant messaging conversation.
