We have few report about this error and not sure why the GroupWise client display the error. Please see below some suggestions to resolve the issue:
– Rebooting the computer.
– Reducing the number of messages being saved (We recommend to save a small batch of messages as GroupWise can slow down dramatically when processing large batch of messages).
– Make sure you are running the latest point release of the GroupWise client.
Hope this helps. Please do not hesitate to contact us if you have any further questions or comments.
