By centralizing communication, shared mailboxes streamline team collaboration, enhance customer service, and improve resource management and accountability. It's no wonder, then, that they are gaining popularity among many businesses -- and if you're using one for Microsoft 365, you'll certainly want to know how they're benefiting your company.
That's what a Microsoft 365 or Office 365 shared mailbox usage report can do. In this blog post, we'll talk about everything you need to know about such a report.
What is an Office 365 Shared Mailbox Usage Report?
A shared mailbox in Office 365, now known as Microsoft 365, is a mailbox that multiple users can use to read and send email messages from a common email address. Shared mailboxes are designed to facilitate collaborative work by allowing multiple team members to access and manage emails collectively. They are commonly used for functions such as customer support, sales inquiries, or any role where emails need to be accessed by more than one person.
An Office 365 shared mailbox usage report is a collection of data and metrics that provides insights into how a shared mailbox is being used within an organization.
What's in an Office 365 Shared Mailbox Usage Report?
What insights can you get out of an office 365 shared mailbox usage report? Here is a detailed breakdown:

Using PowerShell
PowerShell is a powerful tool for generating detailed reports on shared mailbox usage. Here are some useful commands and scripts:
1. Connect to Exchange Online PowerShell
$UserCredential = Get-Credential
Connect-ExchangeOnline -UserPrincipalName $UserCredential.UserName -Password $UserCredential.GetNetworkCredential().Password
2. Get Shared Mailbox Statistics
# Get all shared mailboxes
$sharedMailboxes = Get-Mailbox -RecipientTypeDetails SharedMailbox -ResultSize Unlimited
# Loop through each shared mailbox to get usage statistics
$report = foreach ($mailbox in $sharedMailboxes) {
$stats = Get-MailboxStatistics -Identity $mailbox.Identity
[PSCustomObject]@{
DisplayName = $mailbox.DisplayName
PrimarySmtpAddress = $mailbox.PrimarySmtpAddress
TotalItemSize = $stats.TotalItemSize.Value.ToString()
ItemCount = $stats.ItemCount
LastLogonTime = $stats.LastLogonTime
}
}
# Export the report to a CSV file
$report | Export-Csv -Path "C:\SharedMailboxUsageReport.csv" -NoTypeInformation
3. Example of Specific Detail Retrieval
$sharedMailboxes = Get-Mailbox -RecipientTypeDetails SharedMailbox -ResultSize Unlimited

Write-Output ""
}
Shared Mailbox Usage Report vs Individual Mailbox Usage Report
While both reports provide valuable insights, the shared mailbox usage report is more focused on collaborative and collective usage, permissions, and security within shared environments.
In contrast, the user mailbox usage report is centered around individual user activity and personal mailbox management.
Limitations of the Office 365 Shared Mailbox Usage Report
Office 365 shared mailbox usage reports, while useful, have several limitations. These constraints can affect how effectively administrators can manage shared mailboxes and make informed decisions. Below are some specific limitations and examples of where they apply:
1. Limited Granularity in User Activity
Shared mailbox usage reports typically lack detailed information about individual user activities within the shared mailbox. For instance, the reports may not provide specifics about which user read, replied to, or deleted specific emails.
In a customer support team, knowing which team member responded to a particular customer query can be important for accountability and follow-up. The lack of detailed user activity tracking makes it difficult to identify the responsible team member for any given action.
2. Insufficient Audit Log Detail
While audit logs can be enabled to track certain actions within a shared mailbox, they are not comprehensive by default. Detailed audit logs require specific configurations and may not cover all activities, such as viewing emails or accessing attachments.
For legal and compliance reasons, a financial services firm might need a complete audit trail of all interactions with client emails. If the audit logs do not capture every necessary detail, the firm could face challenges in meeting compliance requirements.
3. Lack of Comprehensive Historical Data
Usage reports may not retain comprehensive historical data over long periods. They often provide data for only the last few months or a specified period, limiting long-term trend analysis.
A potential example? An organization wanting to analyze email traffic trends over the past two years to inform staffing decisions and resource allocation might find that the available reports only cover the last six months, thereby missing important historical patterns.
4. No Insights on Deleted Items
Office 365 shared mailbox usage reports generally do not include detailed information on deleted items, such as which items were deleted and by whom, unless specific audit logging is configured.
In a legal dispute, a company might need to prove that certain emails were deleted maliciously or accidentally. Without detailed deletion logs, it can be challenging to provide the necessary evidence.
5. Limited Customization Options
The built-in reporting tools also offer limited customization. Administrators may not be able to tailor reports to include specific metrics or format data in ways that meet their unique needs.
How might this be a problem? A marketing team may need a customized report showing the volume of email campaigns sent, open rates, and response times. The default shared mailbox usage report may not provide this level of detail or customization, requiring additional manual work or external tools.
6. Incomplete Picture of Collaboration
Additionally, usage reports focus primarily on email activity and may not capture the full scope of collaboration within a shared mailbox, such as calendar usage, task management, or integration with other tools.
A project management team, for instance, using the shared mailbox to coordinate schedules and tasks might not get insights into how effectively they are using the shared calendar and task features, limiting their ability to optimize these collaborative tools.
7. Potential Data Privacy Issues
Another potential challenge to contend with is that detailed reporting on user actions within shared mailboxes might raise privacy concerns, especially in regions with strict data protection laws. Balancing the need for oversight with privacy compliance can be challenging.
For example, in the European Union, under GDPR, monitoring individual user actions within a shared mailbox might require explicit consent from users, complicating the implementation of detailed usage reports without violating privacy regulations.
8. Performance and Scalability Issues
Generating detailed usage reports for large organizations with numerous shared mailboxes can also be resource-intensive, potentially affecting system performance and scalability.
If you work in a multinational corporation with hundreds of shared mailboxes, for instance, you might experience slow performance or incomplete data retrieval when attempting to generate comprehensive usage reports. And this might hinder your ability to manage resources effectively.
9. Dependency on PowerShell for Advanced Reporting
Finally, this kind of report often necessitates the use of PowerShell scripts for more advanced and detailed reporting, which will require specific technical expertise and can be complex to manage.
An organization needing to generate a detailed report on shared mailbox activity, including custom metrics and specific timeframes, might require a skilled IT professional to write and maintain the necessary PowerShell scripts, increasing dependency on specialized skills.
