After upgrading to Notes 8.0.2, a problem similar to the one describe in this technote : http://www-01.ibm.com/support/docview.wss?uid=swg21307609 was happening.
In summary, you have to delete the agent of the mail files in problem (they show how to create an agent to do that) and let the server task recreate it. What I notice is now, the agent that was recreated by the server task is in english but was in french before. How can I fix this situation easly (many databases are involved) ?
Thanks
