Hello All, I have a user who has an MS-Access application used to distribute surveys. The application interops with Outlook to distribute the survey to 995 users. No problems with this application in the past. After selecting the 995 users from a Word document, the application then tries to load the 995 recipients to send them. It loads 65 users, then the following error is encountered: Error: A fatal error has occurred -2147221233 (collaboration data objects -(MAPI_E_NOT_FOUND))) -2147221233. I Googled the error and found: Reference: http://support.microsoft.com/kb/254567 The above page also references http://support.microsoft.com/kb/166599/EN-US/. This page has a registry hack as resolution. This is the fix recommended in the above 2nd KB article: HKEY_LOCAL_MACHINE/Software/Microsoft/Windows Messaging SubsystemTo create the registry entry, do the following: 1. Start Registry Editor (Regedt32.exe) and go to the following key: HKEY_LOCAL_MACHINE/Software/Microsoft/Windows Messaging Subsystem 2. On the Edit menu, click Add Value. 3. Type the following values: String Value: ProfileDirectory Value Data: Path to the directory you want the temporary files to be created in. Example: C:\MyComputer\Temporary. This does not pan out as there are no permission issues and using FileMon, I don't see where anything is trying to access folders for which the user does not have access. Also, a web server nor the IUSR account is not involved in the application. Can anyone help me understand / troubleshoot this error? TIA, Rich
