Now Easily Audit Email Deletion in Office 365
I have created a PowerShell script to find out who deleted an email from the Office 365 mailbox. By using in-built filtering params, you can generate 7 granular email deletion audit reports. https://o365reports.com/2021/09/02/audit-email-deletion-in-office-365-mailbox-powershell/ I have listed a few use-cases of the script below, - Tracks all the deleted emails - Identifies who deleted emails from a shared mailbox - Audits deleted emails from a specific mailbox - Finds deleted emails by subject - Audits email deletion for custom period - Schedules audit report to track email deletionPrimer: How to Use RBAC for Applications to Control App Use of the Mail.Send Permission
The temptation to use the Mail.Send application permission in scripts can lead PowerShell developers into trouble because the permission allows access to all mailboxes, including sensitive executive and financial mailboxes. Fortunately, RBAC for Applications allows tenants to control the access that apps have to mailboxes and other Exchange content. All explained here with an example script to test RBAC of Applications. https://office365itpros.com/2026/02/17/mail-send-rbac-for-applications/Removing Inactive Entra ID User Accounts with PowerShell
The Entra ID Governance solution includes a workflow to detect and remove inactive user accounts. Sounds good, but the same can be done with PowerShell if you want to avoid the cost of Entra ID Governance licenses or want to create a bespoke workflow that’s better suited to the business needs of the organization. Azure Automation would be a good way to process this workflow. https://office365itpros.com/2025/11/17/remove-inactive-user-accounts/Automating Microsoft 365 with PowerShell Second Edition

A reader wants to remove all calendar items over a certain age. Compliance purge actions seem like a good way to do this, but there's a problem that needs to be fixed. eDiscovery purges can do the job, but only if you have eDiscovery Premium. And then there's Graph APIs to consider. All in all, many ways exist to purge calendar items. https://practical365.com/ediscovery-purges/Creating Viva Engage Communities with the Graph API
A new beta Graph API supports the creation of a Viva Engage community. This article explains how to use the Graph SDK to create a new community with the API.

Delegating calendar access is one of the popular Exchange features. As an admin, managing calendar permission is one of the challenging tasks because, Microsoft has not provided GUI based report to view calendars sharing settings. PowerShell needs multiple cmdlets to retrieve calendar permissions. So, I have created a PowerShell script that can generate 6 different calendar permission reports based on the requirement. https://o365reports.com/2021/11/02/get-calendar-permissions-report-for-office365-mailboxes-powershell I have listed a few significant use cases of the script below, Get calendar permissions for all users Get calendars shared with external users List all calendars a user has access to View all calendars’ sharing permissions (including default and anonymous sharing) Export calendar permissions for list of mailboxes – input CSV Get default calendar permission Schedule calendar permission reportAll Emails purged after running Compliance command except those in "top of information store" Folder
