INTRODUCTION
MAPI store providers use the PR_STORE_SUPPORT_MASK property to provide information to clients about the capabilities of the provider. There is a new flag in the PR_STORE_SUPPORT_MASK property that indicates that there is support for Unicode.

Microsoft Exchange Server 2000 and earlier versions and the Outlook 2003 Unicode personal folders (.pst) files advertise this new flag.

Both Microsoft Outlook 2002 and Outlook 2003 use this flag to determine whether Unicode support is available from the Store provider.



MORE INFORMATION
The following is the new flag that is in the PR_STORE_SUPPORT_MASK property:


 * 1) define STORE_UNICODE_OK ((ULONG) 0x00040000)

This flag is not defined in the software development kit (SDK) version of Mapidefs.h. Developers must add this flag to the header file, or they must use the actual flag value when they use this flag in code. Store providers can include this flag in the PR_STORE_SUPPORT_MASK property to indicate that they support Unicode storage. Client programs can look for the presence of the flag to decide whether to request or to save Unicode information to the store.
