Once the module is installed, you can connect to Exchange Online PowerShell by running the following command:

Connect-ExchangeOnline

By following any of these methods, you will establish a secure connection to Exchange Online PowerShell, granting you access to a wide range of powerful commands, including the get-mailbox command.

Now that you are connected to Exchange Online PowerShell, you are ready to execute the get-mailbox command and retrieve valuable information about the mailboxes in your organization.

Retrieving Information about a Single Mailbox

When it comes to managing email in Exchange Online PowerShell, being able to retrieve information about a single mailbox is crucial. Whether you need to gather specific details about a user’s mailbox or troubleshoot an issue, the get-mailbox command is your go-to tool. By using this command in combination with the -Identity parameter, you can easily retrieve information about a single mailbox.

To retrieve information about a specific mailbox, you simply need to provide the mailbox’s alias or display name as the value for the -Identity parameter. For example:

get-mailbox -Identity john.doe@example.com

This command will return important details about the mailbox, including the name, alias, server name, and prohibit send quota. But what if you want to access even more information? That’s where the format-list parameter comes in handy.

By using the format-list parameter with the get-mailbox command, you can display all available properties for the mailbox. This allows you to access a wide range of information, such as the mailbox’s database, retention policy, and delivery restrictions. For example:

get-mailbox -Identity john.doe@example.com | format-list *

This command will provide a detailed output of all the mailbox’s properties, giving you a comprehensive view of the mailbox’s configuration.

In addition to retrieving information about a single mailbox, visualizing data can also be beneficial. To assist with this, here’s an example table showcasing the properties that can be retrieved using the get-mailbox command:


PropertyDescription
NameThe display name of the mailbox.
AliasThe unique identifier for the mailbox.
ServerNameThe name of the server hosting the mailbox.
ProhibitSendQuotaThe mailbox size quota that restricts sending.

Note: This table provides a sample of properties that can be retrieved using the get-mailbox command. The complete list of available properties can be extensive and may vary depending on the version of Exchange Online PowerShell you are using.

By effectively retrieving information about a single mailbox, you can gain insights into its configuration and take appropriate actions for efficient email management.

Accessing Specific Property Values

When working with the get-mailbox command in Exchange Online PowerShell, you have the ability to access specific property values for a mailbox. By customizing the command with the format-list and format-table cmdlets, you can retrieve only the information you need. This allows for greater efficiency and targeted mailbox management.

To access specific property values, you can use the format-list parameter along with the desired properties. For example, let’s say you want to view litigation hold-related properties for a mailbox. Using the format-list parameter, you can specify properties such as DisplayName, LitigationHoldEnabled, LitigationHoldDate, LitigationHoldOwner, and LitigationHoldDuration. This will provide you with detailed information about the litigation hold status and related properties for the selected mailbox.

If you prefer a tabular view of the properties, you can use the format-table parameter instead of format-list. This will display the information in a clean and organized table format, making it easier to review and analyze.

“By accessing specific property values, you can gain deeper insights into mailbox properties and make informed decisions for your email management.”

With the ability to customize the get-mailbox command and retrieve specific property values, you have the flexibility to focus on the most relevant information for your mailbox management tasks.

Let’s take a look at an example of accessing specific property values using the format-list parameter:

PropertyValue
DisplayNameJohn Smith
LitigationHoldEnabledTrue
LitigationHoldDate2021-08-15
LitigationHoldOwnerLegal Department
LitigationHoldDuration90 days

By accessing specific property values within a mailbox, you can gain deeper insights and make informed decisions for your email management tasks. Whether you need to review litigation hold-related properties or other mailbox attributes, customizing the get-mailbox command allows you to obtain the relevant information efficiently and effectively.

Retrieving Information about Multiple Mailboxes

The get-mailbox command in Exchange Online PowerShell is a powerful tool that allows you to retrieve information about multiple mailboxes in your organization. By omitting the -Identity parameter and using the -ResultSize parameter with the value of “unlimited”, you can gather details for all mailboxes within your organization. This command provides a convenient way to access important mailbox information, such as display names, litigation hold status, and more.

To further customize the output, you can utilize the format-table parameter. This parameter allows you to specify the specific properties you want to display in the result, such as DisplayName and LitigationHoldEnabled. By narrowing down the displayed properties, you can focus on the information that is most relevant to your needs.

Below is an example of using the get-mailbox command to retrieve information about multiple mailboxes:

PS C:> Get-Mailbox -ResultSize unlimited | Format-Table DisplayName, LitigationHoldEnabled, Size
DisplayNameLitigationHoldEnabledSize
John DoeFalse250 MB
Jane SmithTrue500 MB
Mike JohnsonFalse100 MB

To retrieve mailbox information for all users in your organization, you can use the Get-Mailbox command without specifying any filters. The -ResultSize parameter set to “unlimited” ensures that all mailboxes are included in the result.

With the ability to retrieve information about multiple mailboxes, you can efficiently manage and monitor your organization’s email environment. Whether you need to analyze mailbox sizes, track litigation hold status, or perform other mailbox management tasks, the get-mailbox command provides the flexibility and power you need.

Filtering Mailboxes Based on Criteria

If you need to narrow down the list of mailboxes you want to retrieve information for, you can use the where-object cmdlet in conjunction with the get-mailbox command. By specifying a filter phrase, you can tell PowerShell which set of mailboxes you are interested in. For example, you can use the where-object cmdlet to filter mailboxes based on specific criteria, such as whether a mailbox has been assigned a litigation hold or if the junk email rule is enabled.

Example: Filtering Mailboxes with Litigation Hold

Suppose you want to retrieve information about all the mailboxes in your organization that have been assigned a litigation hold. You can use the following command:

get-mailbox | where-object { $_.LitigationHoldEnabled -eq $true }

This command uses a filter expression to check if the LitigationHoldEnabled property of each mailbox is set to true. Only the mailboxes that meet this criteria will be returned in the output.

Example: Filtering Mailboxes with Enabled Junk Email Rule

If you want to filter mailboxes based on whether the junk email rule is enabled, you can use the following command:

get-mailbox | where-object { $_.JunkEmailEnabled -eq $true }

This command checks the JunkEmailEnabled property of each mailbox and returns only the mailboxes where the property is set to true in the output.

By using the where-object cmdlet in combination with the get-mailbox command, you can easily filter and retrieve information about specific sets of mailboxes that meet your criteria.

Filter CriteriaCommandResult
Mailboxes with Litigation Holdget-mailbox | where-object { $_.LitigationHoldEnabled -eq $true }Returns mailboxes that have been assigned a litigation hold.
Mailboxes with Enabled Junk Email Ruleget-mailbox | where-object { $_.JunkEmailEnabled -eq $true }Returns mailboxes where the junk email rule is enabled.

Accessing Additional Mailbox Details in Active Directory

While the get-mailbox command provides a wealth of information about mailboxes, there may be additional details stored in Active Directory that you may need to access. To retrieve these details, you can use the Get-ADUser cmdlet along with the -Properties parameter to specify the desired properties. This allows you to access a variety of additional information related to a user’s mailbox.

When using the Get-ADUser cmdlet, you can specify properties such as:

  • Title – The job title of the user associated with the mailbox
  • OfficePhone – The office phone number of the user
  • MobilePhone – The mobile phone number of the user
  • Company – The company the user is affiliated with

By accessing these additional details from Active Directory, you can gather a more comprehensive understanding of the users and their associated mailboxes within your organization.

With the Get-ADUser cmdlet and the -Properties parameter, you can access valuable information that may not be available through the get-mailbox command alone. This allows for a more complete and detailed view of your organization’s mailbox ecosystem.

Optimizing Mailbox Management with PowerShell

When it comes to optimizing mailbox management, PowerShell is an invaluable tool. With its automation and bulk management capabilities, PowerShell allows us to streamline processes and improve efficiency in managing our email environment. By utilizing the get-mailbox command and other PowerShell cmdlets, we can take full control of our mailbox management tasks.

Retrieving Specific Property Values

One of the key advantages of using PowerShell for mailbox management is the ability to retrieve specific property values. With the get-mailbox command, we can access a range of properties and values associated with an Exchange Online mailbox. By specifying the desired properties, such as display name, mailbox size quota, or litigation hold-related properties, we can easily retrieve the information we need.

Filtering Mailboxes Based on Criteria

Another powerful feature of PowerShell is the ability to filter mailboxes based on specific criteria. By combining the get-mailbox command with the where-object cmdlet, we can narrow down our search and retrieve information only for the mailboxes that meet our defined criteria. Whether you want to filter mailboxes based on litigation hold status or enable the junk email rule, PowerShell provides the flexibility to tailor your mailbox management tasks.

Accessing Additional Details in Active Directory

While the get-mailbox command provides comprehensive information about mailboxes, some additional details may be stored in Active Directory. By using the Get-ADUser cmdlet along with the -Properties parameter, we can access these additional details. This allows us to retrieve information such as the user’s title, office phone, mobile phone, and company, giving us a more complete picture of the mailbox owner.

To summarize, PowerShell is a powerful tool for optimizing mailbox management. It allows us to retrieve specific property values, filter mailboxes based on criteria, and access additional details in Active Directory. By harnessing the capabilities of PowerShell, we can enhance our productivity and effectively manage and organize our email environment.
