EXCHANGE SERVER PATCH ALERT
Microsoft is releasing patches for multiple different on-premises Microsoft Exchange Server zero-day vulnerabilities that are being exploited by a nation-state affiliated group.
The vulnerabilities exist in on-premises Exchange Servers 2010, 2013, 2016, and 2019. Exchange Online is not affected.
To minimize or avoid impacts of this situation, Microsoft highly recommends immediate action to apply the patches for any on premises Exchange deployments you have. The first priority being servers which are accessible from the Internet (e.g., servers publishing Outlook on the web/OWA and ECP).
To patch these vulnerabilities, you should move to the latest Exchange Cumulative Updates and then install the relevant security updates on each Exchange Server.

Skype for Business Online Retirement
On July 30, 2019, Microsoft announced July 31, 2021 will mark the official retirement of Skype for Business Online at which time access to and support for the service will end. This news reflects Microsoft’s focused investment in Microsoft Teams, expanding on capabilities in Skype for Business Online by bringing together calling, chat, meetings, and Office 365 and third-party productivity apps in single, intelligent hub. The richer functionality of Microsoft Teams enables organizations to move faster and collaborate more efficiently, and replaces Skype for Business Online as the core communications client for Office 365.
With the focus of helping customers transition from Skype for Business Online to Teams, as of September 1, 2019, no new tenants will be on-boarded to Skype for Business Online. Customers actively using Skype for Business Online will still be able to add new users to their tenant. While many organizations across the globe have successfully upgraded to Teams, the July 31, 2021 retirement provides 24 months for remaining Skype for Business Online customers to make the transition. To maximize the economic and cultural benefits Teams brings, we encourage you to begin planning your upgrade today.
Skype Consumer and Skype for Business Server services will not be impacted by the retirement of the Skype for Business Online service and current Skype for Business Online customers should expect no change in the quality service up to its retirement date.
Read more about the momentum behind Microsoft Teams and the Skype for Business Online retirement announcement at the Microsoft Tech Community Teams blog.
Please let me know your availability for time to connect and discuss how we can support your business and the transition to Microsoft Teams.
