PR_STORE_SUPPORT_MASK 

The PR_STORE_SUPPORT_MASK property contains a bitmask of flags that client applications should query to determine the characteristics of a message store.

Quick Info

Remarks

The PR_STORE_SUPPORT_MASK property discloses the capabilities of a message store to client applications planning to send it a message. The flags can facilitate decisions by a client or another store, such as whether to send PR_BODY6E9KHO or only PR_RTF_COMPRESSED2DC.EZL. A client should never set PR_STORE_SUPPORT_MASK; an attempt returns MAPI_E_COMPUTED.

One or more of the following flags can be set for the PR_STORE_SUPPORT_MASK bitmask:

STORE_ATTACH_OK

The message store supports attachments (OLE or non-OLE) to messages.

STORE_CATEGORIZE_OK

The message store supports categorized views of tables.

STORE_CREATE_OK

The message store supports creation of new messages.

STORE_ENTRYID_UNIQUE

Entry identifiers for the objects in the message store are unique, that is, never reused during the life of the store.

STORE_MODIFY_OK

The message store supports modification of its existing messages.

STORE_MV_PROPS_OK

The message store supports multivalued properties, guarantees the stability of value order in a multivalued property throughout a save operation, and supports instantiation of multivalued properties in tables.

STORE_NOTIFY_OK

The message store supports notifications.

STORE_OLE_OK

The message store supports OLE attachments. The OLE data is accessible through an IStorage interface, such as that available through the PR_ATTACH_DATA_OBJLMT9.H property.

STORE_PUBLIC_FOLDERS

The folders in this store are public (multi-user), not private (possibly multi-instance but not multi-user).

STORE_READONLY

All interfaces for the message store have a read-only access level.

STORE_RESTRICTION_OK

The message store supports restrictions.

STORE_RTF_OK

The message store supports Rich Text Format (RTF) messages, usually stored compressed, and the store itself keeps PR_BODY6E9KHO and PR_RTF_COMPRESSED2DC.EZL synchronized.

STORE_SEARCH_OK

The message store supports search-results folders.

STORE_SORT_OK

The message store supports sorting views of tables.

STORE_SUBMIT_OK

The message store supports marking a message for submission.

STORE_UNCOMPRESSED_RTF

The message store supports storage of Rich Text Format (RTF) messages in uncompressed form. An uncompressed RTF stream is identified by the value dwMagicUncompressedRTF in the stream header. The dwMagicUncompressedRTF value is defined in the RTFLIB.H file.

An RTF version of a message can always be stored, even if the message store is non-RTF-aware. If the STORE_RTF_OK bit is not set for a particular store, a client maintaining RTF versions must itself call the RTFSync72QW74 function to keep the PR_BODY6E9KHO and PR_RTF_COMPRESSED2DC.EZL versions synchronized for text content. RTF is always stored in PR_RTF_COMPRESSED, whether it is actually compressed or not.
