Hi, I am trying the e-mail dispatcher. When I start the dispatcher it works well around 20 hours and then it stop a work. NAS console shows status “Started” and there is message in the Event Log: The call to member Logon failed. Collaboration Data Objects returned the following message: [Collaboration Data Objects - [MAPI_E_INVALID_OBJECT(80040108)]] When I will stop and start the NAS (throught the NAS console) it works again around 20 hours. I have Navision 3.70A, Windows 2003 server, Outlook 2003 and the period of the dispatcher in 2 minutes. Any idea? Stefan
