Managing mailboxes in Exchange Server 2007 (Part 2)

We have seen the first part about managing mailboxes in Exchange Server 2007, in part two we can analyze this issue in more depth. In this article, we will look at information in mailboxes, blocking, reconnecting and advanced mailbox features.

Information from mailboxes

After creating mailboxes, you will get information about them using the Exchange Management Shell. To do that, you can use two cmdlets:

1. get-mailboxStatistics
2. get-mailboxFolderStatistics.

Using the Get-MailboxStatistics cmdlet as shown in Figure 1, you can get some information from the mailbox such as the quality and quantity of the items, the quality and the number of deleted items, the time of last login and logout. To get this information you use the following syntax:

Get-MailboxStatistics |fl

fl is the alias of the cmdlet format list, allowing to format the output as a attribute list in which each attribute appears on a new line.

Sometimes we need more information than Get-MailboxStatistics, in which case you can use Get-MailboxFolderStatistics to get as much information as the number of items and the size of each folder for a specific mailbox ( Figure 2).

The command and syntax are shown below:

Get-MailboxFolderStatistics

Define features for a specific mailbox

Another important feature allows you to configure some features of Outlook Web Access. To configure at the virtual directory level you can follow the steps below:

1. Open the Exchange Management Console

2. Expand Server Configuration

3. Click Client Access

4. In Work Panel choose your server

5. In the Result Panel, click OWA

6. Click Properties in the Actions pane (Figure 03).

7. Go to Segmentation tab (Figure 04), you can enable or disable some features of OWA by using virtual directory for all users.

However, sometimes we need to be more flexible, for example when a particular user cannot change his password or in another specific situation, so with this problem we can manage Those features are via the Set-CASMailbox cmdlet.

Here are some key features that we can change at the user level using the Set-CASMailbox cmdlet:

1. MAPIBlockOutlookNonCachedMode
2. MAPIBlockOutlookRpcHttp
3. MAPIBlockOutlookVersions
4. MAPIEnabled
5. OWAActiveSyncIntegrationEnabled
6. OWAAllAddressListsEnabled
7. OWACalendarEnabled
8. OWAChangePasswordEnabled
9. OWAContactsEnabled
10. OWAEnabled
11. OWAJournalEnabled
12. OWAJournalEnabled
13. OWAJunkEmailEnabled
14. OWANotesEnabled
15. OWAPremiumClientEnabled
16. OWARemindersAndNotificationsEnabled
17. OWASearchFoldersEnabled
18. OWASignaturesEnabled
19. OWASpellCheckerEnabled
20. OWATasksEnabled
21. OWAThemeSelectionEnabled
22. OWAUMIntegrationEnabled
23. OWAUNCAccessOnPrivateComputersEnabled
24. OWAUNCAccessOnPublicComputersEnabled
25. OWAWSSAccessOnPrivateComputersEnabled
26. OWAWSSAccessOnPublicComputersEnabled

By default, all of these properties are empty, users use OWA virtual directory settings. When allowing any attribute, other attributes are automatically given $ false , so you will have to enable the attribute to be used by the user.

Here are some examples of what you can do with the Set-CASMailbox cmdlet:

1. Disable E-mail signature in OWA

Set-CASMailbox -OWASignaturesEnabled: $ false

2. Set up a user to use only the OWA Light version

Set-CASMailbox -OWAPremiumClientEnabled: $ false

3. Disable the change of password.

Set-CASMailbox -OWAChangePasswordEnabled: $ false

Disable Mailboxes

When disabling a mailbox in Exchange Server 2007, you must remove the exchange properties of this mailbox but the user is still in Active Directory. To disable a mailbox you should proceed as follows:

1. Open the Exchange Management Console

2. Expand Recipient Configuration

3. Click Mailbox

4. Select a mailbox and click Disable in the Actions pane (Figure 05).

5. On Microsoft Exchnge page, a dialog with a new message will appear asking if you really want to disable that user, click Yes to continue (Figure 06).

Obviously we can remove the mailbox using Exchange Management Shell with the remove-mailbox cmdlet. Then disable it, to confirm this operation press Y and Enter (Figure 07).

Remove mailboxes

We can remove a mailbox but need to know that removing a mailbox will also delete the object in Active Directory.

1. Open the Exchange Management Console

2. Expand Recipient Configuration

3. Click Mailbox

4. Select the mailbox and click Remove in the Actions pane (Figure 08).

Another way to do this is to use the Exchange Management Shell, using the remove-mailbox cmdlet (Figure 10):

Remove-Mailbox

Reconnect mailboxes

So complete the process of creating and removing / disabling a mailbox, we will then see how to reconnect a removed or disabled mailbox. By default, all removed or disabled mailboxes are in the archive for about 30 days. This value can be set at the mailbox storage level. To change this parameter, proceed as follows:

1. Open the Exchange Management Console

2. Expand Server Configuration

3. Click Mailbox

4. Select your server in the Mailbox Pane

5. Click Mailbox Store in the Result Pane

6. Click Properties in the Actions pane (Figure 11).

7. Go to the Limits tab

8. In the Deletion Settings section, you can select the number of days that a disconnected mailbox still exists in Mailbox Database (Figure 12).

The connection still exists in the mailbox store

Now that we know how long it will take for a disconnected mailbox to remain in the archive, proceed to check the mailboxes and connect them as follows:

1. First create a user in Active Directory User and Computers called user.recovery

2. Open the Exchange Management Console

3. Expand Recipient Configuration

4. Click Disconnected Mailbox

5. You will see all disconnected mailboxes in the work pane. Select the disconnected user and click Reconnect in Actions pane (Figure 13)

6. Introduction . On the Introduction page, select User Mailbox then click Next to continue (Figure 14).

Figure 14 : Select mailbox type to reconnect

7. Mailbox Settings . You have created a new mailbox called user.recovery . Now you can click Existing user and click user.recovery, which will connect to the contents of the mailbox that has been disabled or removed. (Figure 15). On the Mailbox Settings page, there are two options:

Matching user : To locate a user account valid with the mailbox object, Exchange will use the LegacyExchangeDN and DisplayName properties of the Exchange storage mailbox object. If Exchange does not find what to choose for an existing user.

Existing User : If you want to connect the mailbox to a user other than a valid user. Click Browse to see the list of users in Active Directory. This list will only have users without the relevant mailbox.

For the purposes of this article, click Existing User and select user.recovery on the Browse button, then click Next to continue (Figure 15).

8. Connect mailbox . Shows that the entire configuration will be completed in the next step. Click Connect to continue (Figure 16).

has been successfully completed

10. Now user.recovery can log in to their mailbox and check all the content they already own.

Change rule limits in mailboxes

This is a point not to be missed in this article; A new feature of Exchange Server 2007 allows changing the size of RulesQuota. By default, the value is 64KB but they have been upgraded to 256 KB per user.

Another interesting point is that this value is only applicable for valid roles; all other roles that have been disabled are not included in the RulesQuota value.

To change the RulesQuota value in Exchange Server 2007, you can use the cmdlet in Exchange Management Shell:

Set-Mailbox -RulesQuota: 256KB

Conclude

In this last article on mailbox management, we introduced some features at the mailbox level and observed the process of removing and restoring mailbox content.
