We have Microsoft Office Live Communications Server public IM connectivity working. External IM users can see and send messages most of the time.
All of a sudden IM users start to get a message sending to the Communicator user indicating:
The following message could not be delivered to all recipients:
We can send to them they cannot send to us even when they get the send failure they can receive a message. Later without doing anything messages will start to flow again. No errors are given on the OCS servers.
Before we don't get the message the Communicator user will see the message indicating the IM user is typing.
Other Communicator users will be receiving IM messages from other users at the same time the failure is taking place.
The Communicator users are local to the OCS. The IM users that fail are different users at different times.
