What is Office 365 Mailbox Permissions Report?

The Office 365 Mailbox Permissions Report is a PowerShell script designed to assist administrators in auditing and managing access rights across Exchange Online user and shared mailboxes. By scanning for permissions, this tool identifies who has access to these mailboxes and distinguishes non-standard permissions that may be in place. The report, which is generated as a CSV file, is comprehensive in that it lists both standard and non-standard permissions, providing a clear overview of mailbox access configurations.

Furthermore, the script is versatile and supports various authentication methods including Multi-Factor Authentication (MFA) and certificate-based authentication. It is also capable of exporting permission details for all mailboxes or can be targeted to specific mailboxes based on the administrator’s needs. With the ability to filter output by permission type such as Send-as, Send-on-behalf, or Full access, the tool offers flexibility to focus on particular areas of interest. The Office 365 Mailbox Permissions Report script is an invaluable resource for maintaining proper mailbox permissions and ensuring secure and efficient mailbox management within an organization.

Export Office 365 Mailbox Permissions Report to CSV

Using Get-MailboxPermissions PowerShell Script

One method to export Office 365 mailbox permissions is by utilizing the Get-MailboxPermissions PowerShell script. This script generates a list of mailbox permissions for all users and shared mailboxes in the Office 365 environment. The permissions that are included in the report cover Full Access, Send As, and Send on Behalf privileges. To prepare for the export, the script requires a connection to Exchange Online PowerShell, which is established using the Connect-ExchangeOnline cmdlet. After gathering the necessary permissions with the Get-MailboxPermissions cmdlet, the script offers a preview of the data using the Out-GridView cmdlet. Finally, the script exports the permissions report to a CSV file, which is saved to the C:\temp folder.

Viewing Permissions Before Export

Prior to exporting the mailbox permissions report, it is possible to display the permissions for review. The script employs the Out-GridView cmdlet for this purpose, allowing for an interactive grid view of the permissions that will be included in the report. This step ensures that the exported data is accurate and relevant to the administrator's needs before it is saved to the CSV file.
