Microsoft is increasing the maximum auto-expanding archive capacity for eligible Exchange Online mailboxes from 1.5 TB to 3 TB. Rollout begins in mid-October 2026 and is expected to complete by late October. The increase applies to mailboxes assigned the following eligible licenses:

  • Office 365 E5, A5, or G5
  • Microsoft 365 E5, A5, or G5
  • Microsoft 365 Purview Suite
  • Microsoft 365 Purview Suite FLW, EDU, or GOV
  • Microsoft Defender + Purview Suite FLW
  • Microsoft 365 F5 Compliance
  • Microsoft 365 F5 Security + Compliance
  • The combination of the eDiscovery & Audit, Insider Risk Management, and Information Protection & Governance mini suites

Qualifying offerings that include Microsoft Purview E5 capabilities, such as E7, also support the increase. For all other licenses, the existing 1.5 TB limit remains unchanged.

For E5 licenses, verify that Records Management is selected and remains enabled in the user’s license settings.

If auto-expanding archiving is already enabled, no additional configuration or per-GB charge applies. Existing archive content, retention policies, and holds are unchanged. Verify license eligibility and monitor archive growth.

MC1472592 – Microsoft Purview: Auto-expanding archive capacity increases to 3 TB for eligible mailboxes

What and why

Microsoft Purview Data Lifecycle Management is increasing the maximum auto-expanding archive capacity for eligible Exchange Online archive mailboxes from 1.5 TB to 3 TB. This enhancement helps organizations retain and manage larger volumes of archived email content without requiring manual archive expansion processes or support requests. Eligible mailboxes with auto-expanding archiving enabled will continue to grow automatically as needed.

Rollout schedule

  • General Availability (Worldwide): Beginning in mid-October 2026 and expected to complete by late October 2026

Impact on your organization

Who is affected

  • Administrators responsible for Microsoft Purview Data Lifecycle Management and Exchange Online archiving
  • Users assigned eligible licenses that support the increased archive capacity

Platforms and services

  • Microsoft Purview Data Lifecycle Management
  • Exchange Online
  • Exchange Online Archiving

What will happen

  • Eligible archive mailboxes with auto-expanding archiving enabled can automatically expand beyond the current 1.5 TB limit up to a maximum of 3 TB per mailbox.
  • No additional configuration is required for eligible mailboxes that already have auto-expanding archiving enabled.
  • No per-GB consumption charge is introduced as part of this change.
  • Existing archive content, retention configurations, policies, and holds are unchanged.
  • No new administrator workflow, user experience, or user interface is introduced.
  • Mailboxes that do not have an eligible license will continue to be limited to 1.5 TB.

Eligible licensing includes:

  • Office 365 E5, A5, and G5
  • Microsoft 365 E5, A5, and G5
  • Microsoft 365 Purview Suite
  • Microsoft 365 Purview Suite FLW, EDU, and GOV
  • Microsoft Defender + Purview Suite FLW
  • Microsoft 365 F5 Compliance
  • Microsoft 365 F5 Security + Compliance
  • Combination of the eDiscovery & Audit and Insider Risk Management mini suites together with the Information Protection & Governance mini suite

Note:* The maximum auto-expanding archive capacity supported through this feature is 3 TB per mailbox for eligible licenses.

**This feature is available to customers licensed with Microsoft Purview E5 or higher qualifying offerings that include Purview E5 capabilities ex E7.

Action required and recommendations

No action is required if eligible mailboxes already have auto-expanding archiving enabled.

We recommend that administrators:

  • Review license assignments for users with large archive mailboxes to confirm eligibility.
  • Monitor archive mailbox growth using Exchange Online PowerShell.
  • Identify mailboxes approaching their applicable archive capacity limits.
  • Update internal documentation, retention guidance, and help desk materials to reflect the new 3 TB limit.
  • Review licensing and retention strategies for users whose archive mailboxes are not eligible for the expanded capacity.

Join us for a practical walkthrough of the latest Microsoft Purview Auto Labeling improvements designed to help organizations scale sensitivity labeling across SharePoint and OneDrive with greater confidence. We’ll cover expanded scale limits, broader simulation, improved policy scoping, and upcoming enhancements for richer evidence and broader file coverage.

You’ll learn how these updates help compliance and security teams validate policies before enforcement, monitor labelling activity across the tenant, reduce policy sprawl, and better explain labelling outcomes to stakeholders. This session is ideal for Purview admins, compliance teams, security architects, and partners helping customers operationalize sensitivity labelling at enterprise scale.

Starting with the July 14, 2026 Extended Security Update period for SQL Server 2016, migrating a workload to an Azure VM no longer provides free access to Extended Security Updates for SQL Server 2016. See the following documentation:

Retroactive billing for “missed months” of Extended Security Updates
Additionally, customers that enroll in Extended Security Updates after the end of support date for the product, they will be billed a one-time upfront charge for the months they missed after the end of support date, with billing coming in at the end of the month. For example, if a SQL Server 2016 customer enrolls in January 2027, they will receive a one-time back-bill for July, August, September, October, November, and December 2026 during their first month. See the following documentation:

For “Frontier” Microsoft 365 Copilot customers, Microsoft is adding Grok models from SpaceXAI for use with Word, Excel, and PowerPoint – with the intent to roll out model availability broader across other scenarios as we evaluate usage patterns by customers.

Key points:

  • The models require Frontier Program enrollment by the user or the organization in order to use them. If you don’t know what this is, you’re not going to see these models.
  • The model’s availability is disabled by default – and controlled using the same type of subprocessor “switch” as used for Anthropic Claude.
  • The model is only available in Word, Excel & PowerPoint. Availability for “general” Copilot Chat & other scenarios, is pending evaluation of use cases.
  • As a subprocessor, SpaceXAI Grok models when used in this scenario, adhere to the same data privacy & security commitments as documented in the Microsoft Product Terms & Data Protection Addendum, and covered by Microsoft’s Enterprise Data Protection.
  • Usage of the models requires a Microsoft 365 Copilot license,

(Note: Do not confuse this announcement with the article on learn.microsoft.com entitled, “Connect to SpaceXAI models“. This is an older post written for enabling Grok for use with Copilot Studio developers and has existed for more than 6 months. This did not use Grok as a subprocessor and was basically saying “use at your own risk”.)

For those keeping score, Microsoft 365 Copilot has:

TRAINING: Cybersecurity Awareness for Business Users

Every October, people around the world- from students and parents to large organizations and governments- take time to strengthen their online safety habits and learn how to protect their digital lives.  

Microsoft’s pledge to our customers and our community is to prioritize your cybersafety above all else. Whether you’re running a Fortune 100 company, shopping online, or helping your kids with homework, we’re here to help you stay one step ahead of cyber threats. Our goal is simple: to give you the tools, tips, and confidence to be cybersmart every day. 

In the past year, online threats have become more aggressive and harder to spot: 

  • Phishing scams are everywhere—fraudsters now mimic trusted brands to trick you into giving up passwords or personal info. 
  • Fraudulent websites are deceptive and often mimic legitimate businesses or government agencies, luring users into sharing sensitive information like passwords or credit card numbers.   
  • Identity theft is on the rise, with criminals using leaked personal data to open fake accounts or impersonate you online. 

These attacks are fast, sneaky, and can be powered by artificial intelligence. That’s why you need to have a security-first mindset. Today, you need always-on protection that can spot suspicious behavior, predict hacker tactics, and respond quickly—before damage is done. 

The following are a set of resources & training materials to help business users understand the security threats around them both at work and at home.

WHERE ARE TRANSCRIPTS STORED?
If a transcript is generated of a Teams Meeting by a user that organized a meeting or event, the transcript is usually stored in the meeting organizer’s OneDrive for Business storage as a specially created .MP4 file.  The location is usually in something like “C:\Users\<username>\OneDrive – <customername>\Recordings\<meetingname>.mp4”.  Details are available at Teams meeting recording and transcript storage and permissions in OneDrive and SharePoint – Microsoft Teams.

WHY ARE TRANSCRIPTS REQUIRED FOR TEAMS MEETING RECAPS?
A transcript must be created in order to generate Teams Meeting Recaps because Microsoft’s AI processes the transcript after the meeting has ended, which can take several minutes.  In order to enable or disable the ability to generate a transcript, review the following documentation: Admins- Manage transcription and captions for Teams meetings – Microsoft Teams

WHAT OPTIONS ARE THERE FOR MINIMIZING TRANSCRIPT AVAILABILITY?
For organizations that want Copilot generated summaries of their Teams Meetings but concerned about transcript retention, there are 2 options:

  1. EXPIRATION POLICIES: Use Microsoft Purview retention policies to automatically delete Teams transcripts after a specified expiration period.  Establishing expiration policies for transcripts and recordings is standard policy for many organizations. Review the following documentation for more information on this: Manage Teams recording expiration policy – Microsoft Teams | Microsoft Learn
  2. COPILOT WITH NO TRANSCRIPT:  Engage with Copilot during calls and meetings without recording or transcribing. By specifically preemptively setting a Teams Meeting beforehand as using “Copilot without a transcript”, Copilot can generate AI notes and tasks within a Copilot conversation “in-session” (i.e. *during* the meeting) without storing a transcription and recording. Note however that after the meeting, Copilot won’t be available in the meeting’s Recap tab & no Meeting Recap can be generated *after* the meeting – since a transcription was not stored.  Review the docs for this here: https://aka.ms/copilotnotranscript

WHAT KIND OF TEAMS MEETING SUMMARIES ARE THERE?
For background, are only 2 scenarios where “summaries of a meeting” can be generated:

  1. TEAMS MEETING RECAP: The “Teams Meeting Recap” feature requires the initial creation & storage of a transcript so that the AI can generate the summary after the meeting has ended.  All meeting summary solutions operate this way because this is a computationally intensive AI task that may require several minutes to complete – thus a summary cannot be generated until the end of the meeting when the transcript is complete.   For more information about Teams Meeting Recaps, visit: Intelligent recap for Teams calls, meetings, and events – Microsoft Teams
  2. COPILOT IN-MEETING “CATCH UP” WITH NO TRANSCRIPT:  During a meeting, Copilot can summarize key discussion points, including who spoke and what they said.  It also suggests action items and answers any questions you have, in real time *during* the meeting. After the meeting, Copilot won’t be available in the meeting’s Recap tab & no part of the in-meeting summary will be available.

DOWNLOAD: “Advanced Windows Settings” for Windows 11

Okay, so you’ve heard of PowerToys. But did you know that there’s a configuration component of Windows 11’s settings called Advanced Windows Settings that, like PowerToys, is independently developed & updated via the Microsoft Store (or GitHub)?

Advanced Windows Settings requires Windows 11 21H2 (build 22000) or later & provides additional functionality to the Advanced page inside Windows settings. The Advanced settings page in Windows (formerly known as For Developers) brings together settings that help developers and power users be more productive. Open it directly via System > Advanced in Windows Settings.

(It includes one of my favorite hidden features of Windows, “End Task”. which enables “end task” menu item from the taskbar by rick clicking on it.)

We’ve captured the moments from FabCon & SQLCon that everyone is talking about. Whether you were there or not, this is your fast track to staying in the loop.

In this series, we break down keynotes and corenotes into clear insights and standout demos you can use right away. If it mattered at FabCon, you’ll find it here. Join us, get inspired, and stay connected to what’s happening across the Fabric community.
