Our new Exchange 2000 Server, which was a fresh install and migrated the Exchange 5.5 data from old server, now has a few issues with IIS/Public Folders. Example: When trying to access any item in Public Folders via Exchange System Mgr - rec error #80004005 "Operation Failed." I followed Microsoft's recommendations, but was unable to access any Public Folders via MAPI (Outlook) or HTTP. One link said to change the Local System account for the Services, but I do not know where or how to do that. Also, how do I change to Exchange Server Service Account in a Mixed Exchange environment re: another error message when accessing Exch System Mgr - ID#80040e09 "You do not have the rights required to complete the operation?" The majority of the help links offer SQL related remedies -- we do not have SQL on our network. Do you know of anyone else who has had any "Public Folder" or IIS issues relating to those two error ID numbers?
There are a variety of possible causes for 80004005:
For general troubleshooting of this error, see http://support.microsoft.com/default.aspx?scid=kb;en-us;Q289492 and http://www.microsoft.com/exchange/using/tips/Svr_80004005.asp.Also, when in a Windows 2000 mixed-mode domain, make sure you only use Universal Security Groups (USGs) for client permissions. If you use a Universal Distribution Group (UDGs), Exchange tries to convert the UDG to a USG. Because USGs are only available in native-mode, only native-mode domains can perform this conversion. If your Windows 2000 domain is in mixed-mode, you'll get error 80004005. (http://support.microsoft.com/default.aspx?scid=kb;en-us;Q274046). As for 80040e09, log on as the Exchange 5.5 service account and try the function again. If it works, launch Exchange System Manager and run the Exchange Delegation Wizard and grant your account (and other desired accounts) permissions.
