All Versions of On-Premises Exchange Server Vulnerable to New Attack

Posted on by


A newly-discovered vulnerability in Exchange potentially allows attackers to gain control over Active Directory. Since Exchange 2000, Exchange has been a highly-privileged server that’s tightly connected to Active Directory. Add in some NTLM weakness, Exchange Web Services push notifications, and everything comes together for the bad guys.

Exchange 2010 Nears the End

Posted on by


Exchange 2010 will become unsupported on January 14, 2020. It’s time to decide whether to move to Office 365 or Exchange 2016/2019. Exchange 2010 was a really big and important release in the 23-year history of the product, so it’s sad to see it heading to the software scrapyard.

SPO blocks conditional access
SPO blocks conditional access

Azure Conditional Access policies are pretty powerful, especially when applications accommodate their controls. OWA and SharePoint Online can co-operate with conditional access policies to block the ability of Office 365 users to download email attachments and documents. Although not a perfect solution, it’s a good start.

New OWA Makes Categories into Favorites

Posted on by


Microsoft is still building out the new OWA (for Exchange Online) interface. One new feature is the ability to make categories into Outlook favorites. This seems like a small thing, but it’s really quite useful if you make an effort to use categories. Some people will love it. Some will say “blah.”

Microsoft Releases Exchange 2019 Preferred Architecture

Posted on by


Meeting the commitment given at Ignite 2018, Microsoft has published the preferred architecture for Exchange 2019. As you’d expect, the architecture is highly influenced by the cloud. The fingerprints of Exchange Online are all over the document, but at least it’s nice to see some technology (the MetaCache) being transferred from the cloud to on-premises customers.

Outlook Click-to-Run Optimizes AutoDiscover for Office 365

Posted on by


Microsoft has optimized the Click-to-Run version of Outlook for Office 365. There’s nothing startling about that, but the Outlook team didn’t communicate the change well and they weren’t very kind to people who asked them to reconsider the change in UserVoice. That’s not good.

Rights Management, Protection, and Email AutoSignatures

Posted on by


Given the increased ways to apply rights management protection (encryption) to Exchange Online messages, the volume of encrypted traffic should rise. That’s good for users because their email is protected, but it’s not so good for ISVs who must deal with encrypted email. One such example is autosignature products, where server-based components can’t touch protected email to add their text.

Posted on by

Microsoft released lots of information about Exchange 2019 at the Ignite conference. Administrators will love some of the new features, but end users will find little to amuse them.
