On January 10, 2023, Microsoft released new Security Updates for Exchange 2013 CU23, Exchange 2016 CU23 and Exchange 2019 CU11 and CU12.
Recently, Microsoft published a small update on Servicing Exchange. Being a Microsoft Office 365 Apps and Services MVP and Exchange consultant, I pretty much know what’s going on and coming up, but I didn’t see this one coming.
This week Microsoft released new security updates for the following Exchange versions:
On October 11, 2022, Microsoft unexpectedly released new Security Updates (SUs) for Exchange 2013 CU23, Exchange 2016 (CU22 and CU23) and Exchange 2019 (CU11 and CU12).
Microsoft will stop support for basic authentication in Office 365 starting October 1, 2022. Uhm, that’s a week from the time of writing. That sounds scary, but Microsoft is already stopping basic authentication for tenants for quite some time, so chances are that it is already turned off for your organization.
As an Exchange admin you could not have missed it – The Microsoft Exchange Conference 2022. I have always been a big fan of the smaller, dedicated Microsoft conferences since it gives you the ability to learn more in-depth about the product and interact with peers and the Microsoft product group. Because of the pandemic all in-person events were cancelled, but it seems in-person events are getting back slowly. Unfortunately, MEC was still a virtual event.
Microsoft Exchange Server has been around for more than 25 years. To promote Exchange and to help Exchange admins Microsoft organized the Microsoft Exchange Conference or MEC for a long time.
Microsoft has released Security Updates (SUs) for Exchange 2013, Exchange 2016 and Exchange 2019 that address security vulnerabilities rated ‘Critical’ (Elevation of Privileges) and ‘Important’ (Information Disclosure).
By now you must be aware that Microsoft will turn off basic authentication in Office 365 later this year and that will hit Exchange Online severely. It’s not a big deal when it comes to mail clients or the administrator console (EAC), but automation using PowerShell scripts will be impacted and I recently ran into such an issue.
