Se você executar um purge no exchange system manager você obetrá a seguinte mensagem:

—————————
Exchange System Manager
—————————
The operation cannot be performed because this mailbox was already reconnected to an existing user.

ID no: c1034ad6
Exchange System Manager
—————————
OK
—————————

Para resolver isso, consulte o KB:

Existem 2 métodos para se livrar dessas contas, eu achei o primeiro mais prático, segue abaixo:

Method 1: Remove the orphaned mailbox by using Exchange maintenance

1. Start Exchange System Manager.
2. Locate and then click the mailbox store that you want. For example, to locate the Mailbox Store (My_Server) store, follow these steps:

a. Expand Administrative Groups, expand First Administrative Group, expand Servers, and then expand My_Server.
b. Expand First Storage Group, and then click Mailbox Store (My_Server).

3. On the Action menu, click Properties, and then click the Limits tab.
4. Under Deletion settings, type a number that is less than the age of the orphaned mailbox in the Keep deleted mailboxes for (days) box. For a mailbox that is newly orphaned, type 0 (zero).
5. Configure the maintenance schedule. To do this, follow these steps:

a. Click the Database tab.
b. In the Maintenance interval box, click Use custom schedule, and then click Customize.
c. In the list of days, click the current day so that the row for that day is highlighted. This schedules the maintenance for all day.

Note The scheduling of maintenance for all day can be set or removed. To do this, click a day in the list of days.

6. Click OK.
7. Exit Exchange System Manager.
8. Allow for online maintenance to finish. This may take several hours. You will see event ID 1221 logged in the Application log when online maintenance is finished.
9. In Exchange System Manager, use the Run Cleanup Agent on the Mailboxes folder that contains the orphaned mailbox.

O legal é que está separado por papéis, então se você quiser preparar somente o CAS ou HUB, ou os 3 papéis em um um único servidor, você entra no documento.

Isso é bem legal pois te ajuda a criar o registro SPF no seu servidor DNS.

Vou comentar melhor em outro post, mas as vezes só alterando o nível de SCL você já tem uma melhora significante, foi o que aconteceu semana retrasada em um chamado que atendi, só precisa ficar de olho e monitorar os falsos-positivos.

Vou explicar melhor em um artigo como configurar o IMF e quais os níveis SCL.

“Spam Confidence Level Infrastructure

Topic Last Modified: 2005-05-02

Together, Exchange 2003 and Outlook 2003 provide an infrastructure that supports an end-to-end solution to combating spam. Specifically, this infrastructure includes native functionality in Exchange 2003 and Outlook 2003 that allows software vendors to plug-in spam detection filters along the message path. Spam filters evaluate messages and determine how likely it is that a given message is spam. A number between 0 and 9 is assigned; this number is the spam confidence level (SCL). Essentially, the SCL is a normalized value assigned to a message that indicates, based on the characteristics of a message (such as the content, message header, and so on), the likelihood that the message is spam. A rating of 0 indicates that the message is highly unlikely to be spam, while a rating of 9 indicates that the message is very likely spam. The SCL rating is stored as an attribute of the message.

The administrator configures Exchange to handle messages with SCL ratings in way that is appropriate to the environment. For example, a gateway server may discard all spam that has an SCL rating of greater or equal to 7 and pass all messages that rate less than 7 to the Exchange mailbox server. The mailbox administrator may then decide that all messages rating greater or equal to 5 are transferred directly to the user’s Junk E-mail folder, while all messages with a rating of 4 or less are transferred to the Inbox. Finally, the user may have a mailbox setting that treats all mail in the Junk E-mail folder as spam and deletes it. Alternatively, the Exchange administrator may set up a mailbox recipient policy that lowers the retention period (by age or size) in the Junk E-mail folder.

The SCL infrastructure also takes into account the user’s safe, block, and recipient lists, as well as the Exchange filtering lists. For more information about SCL, see Spam Filter on MSDN®.”
