PRB: Can't Set "Allow Upgrade To Large Tables" Option Using Code

You can not find a message store object, folder object property, or registry setting that corresponds to "Allow upgrade to large tables" option for Personal Folders.

No exposed property currently exists for setting this property through any application programming interface (API) or object model.

The "Allow upgrade to large tables" option must be set manually.

This behavior is by design.

Most of the profile properties of the Personal Folders can be set using MAPI. The "Allow upgrade to large tables" option is not set. The following Personal Folders profile properties are exposed to the programmer as defined in "MSPST.H" in the May, 1999 Platform SDK:


See the steps to see the "Allow upgrade to large tables" option:

1. From the Start menu, select Settings and then Control Panel.
2. Double-click Mail or Mail and Fax icon.
3. Click Show Profiles.
4. Select a profile that contains "Personal Folders" and click Properties.
5. Select "Personal Folders" from the list and click Properties.

Note the check box near the bottom of the Personal Folders property page.
