In a Microsoft Exchange Server 2007 environment, the
Set-Mailbox cmdlet fails when you run the cmdlet together with the
EmailAddressPolicyEnabled parameter. Additionally, you receive the following error message:
Set-Mailbox: Exchange Server 2007 <FQDN of the server> returned an error 1727 from the Recipient Update Service
If you use Network Monitor to capture the remote procedure call (RPC) traffic, the captured data contains an RPC_S_ACCESS_DENIED (0x00000005) error.

The Recipient Update Service server imposes its own limit of 65,536 bytes as the maximum RPC size. It does not use the
MaxRPCSize variable that is defined by the Windows RPC server. If a mailbox is contained in many address lists, the RPC data may exceed the 64-kilobyte limit. Typically, this situation may occur when a mailbox is contained in more than 350 address lists.

To resolve this problem, install Update Rollup 5 for Exchange Server 2007.

Description of Update Rollup 5 for Exchange Server 2007
After you apply Update Rollup 5, you can set the maximum RPC size by using a registry entry. To do this, follow these steps.
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
| 1. | Click Start, click Run, type regedit, and then click OK. |
| 2. | Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeAL\Parameters |
| 3. | On the Edit menu, point to New, and then click DWORD Value. |
| 4. | Type RUS Max RPC Size, and then press ENTER. |
| 5. | Right-click RUS Max RPC Size, and then click Modify. |
| 6. | In the Value data box, type the appropriate value, and then click OK.
Note The value that you type inside the Value data box is the maximum RPC size in bytes that the Recipient Update Service server uses. |
| 7. | Exit Registry Editor. |
In addition, a new
UseRusServer parameter is available for the following cmdlets after you apply Update Rollup 5:
| • | Move-Mailbox |
| • | Set-CASMailbox |
| • | Set-Mailbox |
You can use the
UseRusServer parameter to specify which Recipient Update Service server should be used.
