Disable Windows Mobile 6.1 Threaded SMS View

There may be an occasion where you want to restore the original chronological view for the SMS Inbox rather than the new threaded view. One example is where a system programmatically moves or inserts SMS messages into the system because these are not visible in the threaded view (even though the count of unread messages increases). There is a simple registry fix to turn off threading and restore the “classic” view. From the registry editor of your choice browse the device registry for the key:


Under this add a new DWORD value called “SMSInboxThreadingDisabled” and set it to 1. Close the tmail.exe application or soft-reset the device and the regular message view will be used. Set this registry value back to 0 or delete it to restore the default threaded view.
