Good news: I’m starting a new company, which means that at some point in the future everyone is getting another hoodie.

ISO27001 and SOC2 aren’t perfect, but you’re fooling yourself if you think your CISO’s vendor assessment process is better.

@romualpiecyk @mderooij Servers/systems connecting must trust it. Things like third party email gateways, servers where the trust list is not automatically updating.

I’m going to make a video explaining why skills scanners are dumb then never talk about skills again because I hate this topic so much and it’s beyond stupid that it’s getting this much attention.

One thing you can do for your orgs regarding AI security: start thinking about how you can block AI from reading certain data even when you have AI service principals in your environment. Luckily for me, I started researching and testing this a year ago.

@IAMERICAbooted And the logging, output, and error handling are 100x better than anything I've ever written, because I never do those things 🤣

@alitajran The script can return a lot of old devices. Loop through and run Get-EXOMobileDeviceStatistics to get the LastSuccessSync to see if the devices are even connecting anymore.

Starting March 1, 2026, devices using Exchange ActiveSync (EAS) versions lower than 16.1 will no longer be able to connect to Exchange Online! Microsoft is making a change to improve security and reliability in Exchange Online for ActiveSync devices! EAS 16.1 was introduced in June 2016 and provides enhanced compatibility and security. 𝐖𝐡𝐞𝐧 𝐭𝐡𝐢𝐬 𝐰𝐢𝐥𝐥 𝐡𝐚𝐩𝐩𝐞𝐧: This change begins taking effect on March 1, 2026. 𝐇𝐨𝐰 𝐭𝐡𝐢𝐬 𝐚𝐟𝐟𝐞𝐜𝐭𝐬 𝐲𝐨𝐮𝐫 𝐨𝐫𝐠𝐚𝐧𝐢𝐳𝐚𝐭𝐢𝐨𝐧: Organizations using mobile devices with native email apps to access Exchange Online mailboxes via EAS protocol. Apple devices added support for EAS 16.1 in iOS 10 and are unlikely to be affected. The Gmail app and Samsung Mail will have updated versions available before the deadline. For other apps, you should contact your device or application vendor if they are using EAS versions lower than 16.1. 𝐖𝐡𝐚𝐭 𝐰𝐢𝐥𝐥 𝐡𝐚𝐩𝐩𝐞𝐧: - Devices running EAS versions lower than 16.1 will no longer connect to Exchange Online. - Devices using Outlook Mobile are not impacted because they do not use EAS. - This change applies only to Exchange Online, not Exchange Server. 𝐖𝐡𝐚𝐭 𝐲𝐨𝐮 𝐜𝐚𝐧 𝐝𝐨 𝐭𝐨 𝐩𝐫𝐞𝐩𝐚𝐫𝐞: - Verify that all mobile devices and applications are updated to EAS version 16.1 or higher before March 1, 2026. - Admins can generate a report of devices using older EAS versions with the following PowerShell command: Get-MobileDevice | Where-Object {($_.ClientType -eq 'EAS' -or $_.ClientType -match 'ActiveSync') -and $_.ClientVersion -and (version$_.ClientVersion -lt version'16.1')} | Sort-Object UserDisplayName | Select-Object UserDisplayName, UserPrincipalName, DeviceId, DeviceModel - Communicate this change to your helpdesk and end users, and ask them to update if possible. - Update internal documentation as needed. - For assistance, contact your device or application vendor. #Microsoft365 #ExchangeOnline #ActiveSync
