Editing the Registry of a Windows Mobile Device
Sometimes to gain some functionality on a Windows Mobile device you may need to modify its registry. There are several different registry editors you could use to do this, such as SKTools or Total Commander's registry editor.
For this article, I will use PHM Registry Editor to modify the registry of a WM6.5 phone so that all email messages and related attachments are stored on the installed storage card (by default these items are stored in main memory). The required registry changes are:
- To store EMAIL messages to the storage card: HKLM\System\Inbox\Settings\PropertyPath - Create a new string value called PropertyPath, if necessary, and input the new path to use for Email messages (i.e., \Storage Card\Windows\Messaging)
- For store Email attachments to the storage card: HKLM\System\Inbox\Settings\AttachPath - Create a new string value called AttachPath, if necessary, and input the new path to use for email attachments (i.e., \Storage Card\Windows\Messaging\Attachments)
Making the Changes
Open up PHM Registry Editor and select HKEY_LOCAL_MACHINE (referred to as HKLM). Navigate to System > Inbox > Settings. Then tap Edit > New String Value.
Replace the default value name to PropertyPath or AttachPath (depending on which string you are creating) and input the entire path where you want to store your email messages and email attachments.
NOTE: You need to create these folders before you can use them. See "Take Charge of your Files" to learn about the software you could use to create folders and to manage files on your windows mobile device.
After you've created these keys, exit the registry editor and soft reset your device.
Caution! Caution! Caution! Caution!
Before you start poking around in the registry, be sure to backup the entire contents of your mobile device. Then be very careful when messing around in the registry and don't experiment unless you know what you are doing. Deleting or modifying registry keys could render the device useless, requirement a hard reset to return the device to working order.



Hi,
unfortunately i ended up with the Storage card2 issue on my HD2.so im still looking for a working solution.
thanks
The workable solution for me when I encountered that problem was to perform a hard reset and not mess around with changing the storage location for certain applications on my phone. I learned my lesson about that and so now I'm pretty careful about the things I change in the registry and backup my windows mobile devices before messing around with the registry.
