XADM: Disabling Proxy Address Generation Does Not Work (175953)
The information in this article applies to:
- Microsoft Exchange Server 4.0
- Microsoft Exchange Server 5.0
- Microsoft Exchange Server 5.5
This article was previously published under Q175953 SYMPTOMS
The Microsoft Exchange Server version 5.0 and 5.5 Administrator programs
have the ability to disable the generation of proxy addresses for certain
address types. This is done on the Site Addressing page of the Site
Addressing object under the Configuration object.
This functionality only works on Microsoft Exchange Server, version 5.0
or above.
Therefore, if an Exchange Server site contains both version 4.0 and 5.0
or above servers, mailboxes that were created on the version 5.0 or
above server, will not have the proxy addresses automatically created
because the option was disabled. However, if a mailbox is created on a
version 4.0 server, the mailbox will have all the proxy addresses
automatically created.
The same results occur, when mailboxes are modified using the Import/Export
functionality of the Administrator program. If the import is done on a
version 5.0 or above server, the disabled proxy addresses are not added to
the mailboxes, however, if the import is done on a version 4.0 server, the
disabled proxy addresses will be added to the server.
CAUSE
The problem occurs because the functionality to disable certain proxy
addresses from being generated was added in version 5.0.
The System Attendant service is responsible for generating proxy addresses.
It does so by calling the proxy generators registered with the Exchange
Directory, for the current hardware platform. To confirm which proxy
generators are registered, double-click "Configuration\Addressing\E-Mail
Address Generators" in the right pane of the Microsoft Exchange
Administrator program.
In version 5.0 and above, the System Attendant service looks at the
"Disabled-Gateway-Proxy" attribute on the Site Addressing object and
does not call the proxy address generators corresponding to the
address types listed in the above attribute.
In version 4.0, the System Attendant does not use the "Disabled-Gateway-
Proxy" attribute, and calls each proxy address generator registered for the
current hardware platform. This results in the generation of proxy
addresses for address types that have been disabled.
WORKAROUND
In a site with a mixture of version 4.0 and 5.0 or above servers, the
easiest way to generate mailboxes or custom recipients without proxy
addresses of a certain type, is to make all the additions or
modifications are performed on a version 5.0 or above server.
In version 4.0, the only way to prevent the generation of an address is to
remove the proxy address generator.
