Permissions Available in Exchange
The following sections list the different permissions that are available in Microsoft® Exchange. For more detailed information about most of these permissions (such as their hexadecimal, access-mask values), see the Exchange Server 2003 TechCenter, or the Microsoft Windows® 2000 or Active Directory® directory service documentation in the Microsoft Platform SDK.
Exchange uses special permissions internally to govern access to mailboxes, in conjunction with the preliminary checks that it performs. Exchange does not use these permissions for security descriptors. The following table lists these mailbox-specific permissions.
| Exchange permissions | Member permissions or Windows equivalents |
|---|---|
fsdpermUserDeleteMailbox |
DELETE |
fsdpermUserMailboxOwner |
|
fsdpermUserSendAs |

The following tables list the permissions that are used in the Microsoft Windows NT® security descriptor. For more information about these permissions, see the "Security" topic in the "Key Tasks" section of the Microsoft Exchange Software Development Kit (SDK).
The permissions used in the Windows NT security descriptor of a folder are the same whether the folder resides in a mailbox or in a public folder hierarchy. The following tables list these permissions (the permissions listed in the "Standard Windows permissions used in folder security descriptors" table are available on objects throughout Windows 2000).
In the following table, an asterisk (*) denotes an Exchange-specific permission.

Note
In the following table, access rights that belong to the sdrightsIgnored permission are ignored in the determination of an Exchange Canonical ACL. Because the Exchange store ignores these rights, their presence or absence doesn't make an ACL canonical.

Exchange provides an additional control value, EXCHANGE_RM_SET_EXPLICIT_SD, which can be set in the control field of a security descriptor. An administrator can then set the security descriptor of the object explicitly. For more information about setting EXCHANGE_RM_SET_EXPLICIT_SD, see the Windows XP API documentation.
In addition to standard Windows 2000 permissions, Exchange defines a set of extended permissions that pertain specifically to Exchange functions. The following table lists these permissions.
Note
The permissions Create public folder, Create top-level public folder, and Create named properties in the information store can apply to both administrative and non-administrative users.
