I have been working with Microsoft for a week now on the following errors, they even did a Netmeeting session which turned out to be like a PCanywhere session; He or she worked for 3 hours without resolution. The event errors are as follows OALGen encountered error [0x8004010f] while calculating this OAL. This OAL will not be available for client download. (\Global Address List) hing since sliced Bread. OALGen encountered error [0x8004010f] while Loading the template /O=TOWER COMMUNICATIONS GROUP/cn=Configuration/cn=Addressing/cn=Address-Templates. All display templates will not be available for the client download. Now While I cannot get these errors fixed for a while I have another Idea. My outlook 2003 uses the Exchange Server for the Address Provider(go to tools, address book highlight global address list and right click and properties) and I get new and updated Email addresses. The other users show that the address provider is the offline list located on there PC. Does anyone know how to change this so the Exchange Server is the address provider; I cannot change it, Outlook will not let me change it. Thanks Bruce Rose As I am knew to Exchange I am not a whole lot of help at present, but I will get it down and help others in the future.
