This article was previously published under Q216420 SYMPTOMS
You cannot uniquely identify a mailbox across space and time when calling IExchangeManageStore::GetMailboxTable.
CAUSE
IExchangeManageStore::GetMailboxTable returns the following properties:
- PR_DISPLAY_NAME
- PR_EMAIL_ADDRESS
- PR_LOCALE_ID
- PR_MESSAGE_SIZE
- PR_MESSAGE_SIZE_EXTENDED
- PR_CONTENT_COUNT
- PR_ASSOC_CONTENT_COUNT
- PR_NT_USER_NAME
- PR_LAST_LOGON_TIME
- PR_LAST_LOGOFF_TIME
- PR_STORAGE_LIMIT_INFORMATION
- PR_INSTANCE_KEY
Of the above properties, the one that most closely resembles a Globally Unique Identifier is PR_INSTANCE_KEY. While this property is a MAPIUID property, it is not guaranteed to be the same value every time IExchangeManageStore::GetMailboxTable is called.
RESOLUTION
In most cases the only property that is guaranteed to be unique and stable across space and time is PR_ENTRYID. Unfortunately, this property is not returned with IExchangeManageStore::GetMailboxTable. As an alternative to PR_ENTRYID, it is possible to use PR_EMAIL_ADDRESS. Like PR_ENTRYID, this property is guaranteed to be globally unique and stable across space and time.
