3-month Reminder (First published December MC229143): To ensure that we meet performance expectations, we areupdating the supported versions of Outlook for Windows that can connect toMicrosoft 365 services.
Effective November 1, 2021, the following versions ofOutlook for Windows, as part of Office and Microsoft 365 Apps, will not be ableto connect with Office 365 and Microsoft 365 services.
We are updating our receiving limits in Exchange to help prevent attacks on your mail flow experience. Earlier this year in (February MC239262) we announced a stricter enforcement of our mailbox receiving limits. Taking your feedback into consideration, we are releasing an additional limit to block single-sender mail storms and deter DoS attacks.
Our mailbox receiving limits, as previously stated, apply to the messages received by a Microsoft Office 365 mailbox. If volume exceeds 3,600 messages in a given 60-minute window, the mailbox will no longer accept messages from the Internet, from other tenants, or from on-premises senders.
Thank you for using the public preview (MC224257) of Project Moca! It was a success, and we will begin migrating content from Project Moca to the new Outlook Calendar board view in July. All boards and content will be migrated and users will not lose any data.

On August 5, 2021, the Recommended slab will be retired from old versions of Outlook iOS. When the change takes effect, the Recommended slab will silently disappear from the search view in Outlook iOS versions older than 4.31.0.

Microsoft believes it’s critical to keep our customers secure by default. We have determined that legacy overrides tend to be too broad and cause more harm than good. As a security service, we believe it’s imperative that we act on your behalf to prevent your users from being compromised. This means these legacy overrides will no longer be honored for email messages we believe are malicious. We already apply this approach with malware messages and now we have extended it to messages with high confidence phish verdicts. We have been taking a very deliberate approach to rolling out these changes in phases to ensure customers are not surprised and there are no negative side effects. We began to rollout Secure by Default for high confidence phishing messages by the override type starting in December 2020 (Roadmap ID 60827). Today, we’re at a point in our Secure by Default journey where the following overrides are not honored for malicious emails (malware or high confidence phish emails):
This new release will enable some Windows 10 users, who are using Outlook on the web or Outlook for Windows, to see a clickable recommendation to visit the browser extension page for Outlook in Edge where they can choose to install the extension. This notification will be displayed in any Windows browser (i.e., Edge, Chrome, Firefox, Internet Explorer, etc.) and in Outlook for Windows.
Note: If you do not want your users to see the recommendations for the new Microsoft Outlook Extension for Edge, you can opt-out of these for your organization.
We are improving Microsoft Defender for Office automated investigation email clustering and actions to ensure that actions only occur on malicious emails still in the mailbox. This will result in more accurate threat information, with fewer email actions, and refreshed actions/data.

The first contact safety tip that warns users of a suspicious email which could potentially be related to a Business Email Compromise is a feature that exists today (September 2020).
