Hi all,When user in Exchange server A sends a task request to user on Exchange server B the request is malformed in Outlook 2007. The exchange servers are not trusted to one another, nor are they in the same forest.The Task request comes in as a normal email with all the information mucked up.Ideas on how to correct this? It seems sort of silly for two exchange servers to screw this up.Thanks!

Hi,Do you have any agent installed on Exchange Server?If you have anti-virus application, please disable or uninstall it.Please disable all the add-ins in outlook and then check the issue again.Besides, I recommend you to use pipline tracing to trace if IPM.Task change to IPM.note when it leave the exchange organization.
