How Retention Impacts Office 365 Storage

with 2 Comments by Tony Redmond

Office 365 retention policies help organizations keep information for as long as needed. But retention consumes storage. This isn't a problem for Exchange Online, but it is for SharePoint Online, because files held in the Preservation Hold Library are charged against the tenant storage quota. This isn't a reason to not use retention policies, but you should be careful.

Stick or Stay: Should I Upgrade to Exchange 2019?

by Tony Redmond

Exchange 2019 has been around for six months. It's a good time to consider if on-premises organizations should upgrade or stick with the version of Exchange they run today. Exchange 2019 is a solid release, even if Microsoft's engineering efforts are largely focused on the cloud these days. Of course, moving to Exchange Online is an option too, but perhaps not for the dedicated on-premises deployments.

Exchange Privilege Elevation Vulnerability Addressed by Microsoft Patches

with 3 Comments by Tony Redmond

The recent exposure of a privilege elevation vulnerability that exists in the control Exchange has over Active Directory and EWS push notifications is fixed by cumulative updates for Exchange 2013, Exchange 2016, and Exchange 2019 and a roll-up update for Exchange 2010 SP3. These changes mark an architectural modification for Exchange, something that Microsoft is loathe to do outside major releases. Install the updates now!

Why Exchange Transport Rules are a Good Way to Encrypt Email

by Tony Redmond

Exchange Online transport (mail flow) rules are a powerful way to ensure that email from Office 365 tenants to specific recipients are encrypted in a consistent manner. Using rules relieves the need for users to become involved and makes sure that email is protected in a way that recipients can read messages. It's a good way to use the protection features built into Office 365.

Exchange 2010 Nears the End

by Tony Redmond

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.

New OWA Makes Categories into Favorites

by Tony Redmond

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

by Tony Redmond

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 Mobile Gets a New Architecture

by Tony Redmond

Microsoft has simplified the synchronization architecture used to connect Outlook mobile clients to Exchange. The new approach sets the scene for some new functionality, like support for S/MIME and access to shared mailboxes. It's all good and it marks the continued progress of Outlook mobile since the Acompli acquisition in 2014.
