The Microsoft 365 June 2026 updates are among the most important of the year for SMB administrators: 5 feature removals with deadlines to meet, 12 new features including the Copilot Planner agent with general availability, and urgent action required for Kiosk and Frontline mailboxes. If you manage a Microsoft 365 environment in Quebec, here's everything you need to know and do this month.
This information comes from the Microsoft 365 Message Center (admin.microsoft.com), updated for the Microsoft 365 June 2026. Furthermore, if you don't have time to keep up with these updates every month, that's precisely what our proactive IT management service covers.
Quick answer: In June 2026, Microsoft 365 is bringing several changes for admins: new security policies, adjustments to Teams and Exchange, and compliance updates. Reviewing them will prevent service interruptions.
1. Microsoft 365 June 2026: Withdrawals and End of Support
Microsoft is officially retiring five features or plans this month. Here are the five retirements to manage before the deadlines:
End of standalone SharePoint and OneDrive plans: Microsoft 365 June 2026
Microsoft will stop selling standalone SharePoint Online and OneDrive plans to new customers starting June 1, 2026. If your organization is still using these separate plans, existing licenses will remain active. However, any new subscriptions will need to be through Microsoft 365 Business or Enterprise suites. Therefore, now is a good time to review your licensing structure if you have mixed plans.
Sway app for Windows will be retired (June 1, 2026)
Microsoft is retiring the Sway app for Windows on June 1, 2026. However, the web version will remain available at sway.cloud.microsoft. If employees were using the desktop application, redirect them to the web version before the retirement date.
Outlook for Windows report in the EAC (June 2026)
Microsoft is removing the Outlook for Windows report from the Exchange admin center (EAC). Administrators who used this report will now need to consult other reports in the Microsoft 365 admin center.
Teams Live Events will be removed from Microsoft 365 in June 2026
Microsoft is officially retiring Teams Live Events on June 30, 2026. See the Teams Live Events migration guide on Microsoft Learn. Organizations still using Live Events should migrate to Teams Town Halls and the Virtual Event APIs before this date. Integrations that use the Graph API with the isBroadcast also need to be updated.
ACE Assignments/Courses components and Viva Connections web parts (June 30, 2026)
Support for the ACE Assignments and Courses components, as well as the SharePoint Dashboard web parts for Viva Connections, ends on June 30. Microsoft is automatically removing these redundant elements from Viva Connections environments.
2. Action required: Exchange Web Services for Kiosk and Frontline accounts
Check your Microsoft 365 admin center for mailboxes with Kiosk (F1/F3) or Frontline Worker licenses. Then, identify those that use EWS integrations. This is the type of action that, if overlooked, can cause silent failures that are difficult to diagnose.
3. New Microsoft 365 features June 2026
Twelve new features are coming to Microsoft 365 this month. Here are the most relevant ones for small and medium-sized businesses:
Copilot Planner Agent will be generally available in Microsoft 365 starting June 2026
The Copilot Planner agent is now available to all Microsoft 365 Copilot tenants. It allows you to manage tasks and plans directly from the Copilot interface, without leaving your conversation thread. For small and medium-sized businesses (SMBs) that use Microsoft Planner for project management, this integration can significantly accelerate task creation and tracking. If your organization isn't already using Copilot, check out our guide on the benefits of Microsoft Copilot for SMBs .
Teams automatically detects external AI bots in meetings
Teams can now automatically detect external AI assistant bots (such as third-party AI note-takers) attempting to join a meeting and place them in the lobby pending explicit approval from the organizer. This is an important feature for SMEs concerned about the confidentiality of their meetings.
SharePoint and OneDrive: New File Quarantine (DLP)
A new data loss prevention (DLP) action called "File Quarantine" automatically isolates files that violate compliance policies and replaces them with a personalized message. This is useful for organizations that handle sensitive data subject to regulations (Law 25, GDPR, HIPAA).
SharePoint: New report on "Everyone" permissions
SharePoint Online adds a report that lists all files and folders whose permissions have been granted to the "Everyone" or "Everyone except external users" groups. This is a valuable tool for security audits. Many small and medium-sized businesses have files shared too widely without even realizing it.
Teams allows you to report suspicious external contacts
Teams users can now directly report suspicious external contacts (potential phishing or social engineering) from within the Teams interface. This allows the security team to receive these reports and respond more quickly to phishing attempts via Teams.
Usage-based billing for High Volume Email (June 1, 2026)
Usage-based billing for High Volume Email (HVE) begins on June 1, 2026, at $42 USD per million recipients. If your organization sends large volumes of email through Microsoft 365 (newsletters, automated notifications), review your configuration to avoid unexpected charges.
Copilot license request management page
Microsoft 365 adds a dedicated Copilot license request page to the admin center, centralizing the management of user Copilot access requests. Available now.
4. Improvements and feature changes in Microsoft 365 June 2026
Zero-hour Auto Purge: Microsoft 365 security update June 2026
ZAP (Zero-hour Auto Purge) is Microsoft Defender's technology that retroactively deletes detected malicious emails after they have been delivered. It now extends its coverage to emails in the "Deleted Items" folder. This provides an additional layer of protection against threats that might have been manually deleted but not neutralized.
Entra: App Instance Lock is enabled by default on new applications
Microsoft Entra now enables App Instance Lock by default for newly created applications, protecting sensitive service principal properties from unauthorized modifications. Therefore, no action is required: new applications automatically benefit from this enhanced protection.
Outlook improves mail merge and mailings
The new Outlook for Windows and the web version improve the mail merge function with the insertion of dynamic fields for personalized communication at scale. This is useful for small and medium-sized businesses (SMBs) that send targeted communications from Outlook.
Important changes to note
- Teams: Profanity filter disabled by default in subtitles for unconfigured users, improving transcription accuracy.
- SharePoint and OneDrive DLP: Administrators can now configure policy tips and email notifications independently of each other.
- Entra Connect: Microsoft strengthens security by blocking "hard matching" to prevent account takeover vulnerabilities on users with assigned roles.
- Clipchamp license names will be updated in Microsoft 365 billing and reporting starting mid-June 2026.
- Teams: Private channel migration : Microsoft will automatically remove empty private channels or those composed only of guests that block migration, unless an internal owner is manually assigned before June 5, 2026.
5. Frequently Asked Questions about the June 2026 Microsoft 365 Updates
How can I tell if my organization is affected by the withdrawal of Exchange Web Services for Kiosk accounts?
Sign in to the Microsoft 365 admin center (admin.microsoft.com) and check your active licenses. Identify users with F1, F3, or Frontline Worker licenses, and then check if any applications or integrations in your organization are using EWS with those accounts. If you're unsure, contact your IT provider, as improper management of this change can cause silent outages that are difficult to diagnose.
What if we are still using Teams Live Events?
First, migrate to Teams Town Halls before June 30, 2026. Town Halls offer comparable features. Microsoft officially recommends them as an alternative to Live Events. If you have custom integrations with the isBroadcast API, update them to use the Virtual Event APIs.
Does the new SharePoint file quarantine feature activate automatically?
No. An administrator must configure File Quarantine (DLP) in the Microsoft Purview compliance portal. You define the policies that trigger the quarantine. You also choose the message displayed to users who attempt to access an isolated file.
Is the Copilot Planner agent included in my current Microsoft 365 license?
Users with an active Microsoft 365 Copilot license can access the Copilot Planner agent. Microsoft 365 Business Basic, Standard, or Premium licenses do not include it. If your team doesn't yet have Copilot licenses, contact your Microsoft partner. They can then assess whether the investment is worthwhile for your needs.
