Exchange Online Reports

Mailbox permissions include send as, send on behalf of, and full access permissions. Besides these, there are certain other non-owner and owner permissions like folder access and read permissions for mailboxes. There are also a couple of PowerShell commands for configuring and monitoring mailbox permissions.

PowerShell cmdlets for configuring mailbox permissions

  1. Get-MailboxPermission [-Identity] <MailboxIdParameter> [-Owner] [-Credential <PSCredential>] [-DomainController <Fqdn>] [-ReadFromDomainController] [-ResultSize <Unlimited>] [<CommonParameters>]

    Using this cmdlet, you can find out which users in your Exchange organization have what permissions for a particular mailbox. This cmdlet also displays a list of all the mailbox permissions (owner and non-owner).

  2. Add-MailboxPermission [-Identity] <MailboxIdParameter> -AccessRights <MailboxRights[]> -User <SecurityPrincipalIdParameter> [-AutoMapping <Boolean>] [-Confirm] [-Deny] [-DomainController <Fqdn>] [-IgnoreDefaultScope] [-InheritanceType <ActiveDirectorySecurityInheritance>] [-WhatIf] [<CommonParameters>]

    This cmdlet can be used to provide mailbox permissions such as send as, send on behalf of, full access, or owner permissions to any user in your organization for a particular mailbox.

    These are just the basic scripts. To address other needs such as triggering real-time alerts on permission changes, or saving the report in a specific folder/network share, the scripts have to be modified. This will only make the script more complex. Exchange Reporter Plus offers purpose-built reports to meet such complex needs.
