Hi, I have problems synchronizing a MDA (Windows Mobile v6) to Exchange and to local machines: - The Exchange server is on the first LAN together with the first client. Both are in the same Active Directory structure. The Exchange server is not reachable from outside. -> I can sync the device on the first client machine, including Outlook and OneNote Mobile. - A second LAN has no connection to either the Exchange server or the Domain of the first LAN but uses a different Domain and no Exchange server. -> I can synchronize the device to a local Outlook and transfer e.g. Contacts, but OneNote refuses to sync. Message: "Attention required", no further explanation. I have tried more than one client. All clients are running ActiveSync v4.5, Outlook v2003 and OneNote v2007. The error seems to be a common one, just do a search for "activesync onenote attention required" on Google. How can I get the MDA to sync with OneNote on the second LAN? Regs, 150d
