No Surprise That Exchange Online Uses Windows Server Core

by Tony Redmond

A recent Microsoft post contained the news that Exchange Online uses Windows Server Core. That might be news to some, but not to anyone who's been following the advice of the Exchange product group. Exchange Online doesn't use virtual servers, follows a preferred architecture, wants to reduce the potential attack surface, and extract as much CPU as possible out of its servers. All good reasons why Windows Server Core helps.

Making the Exchange – Azure Active Directory Connection More Reliable

by Tony Redmond

Microsoft posted an odd blog on September 9 to announce improvements in the relationship between Exchange Online and Azure Active Directory. Many Office 365 tenants might have ignored the post, but it's actually about a piece of important work to help the service run better. Many updates happen to Exchange Online objects that need to be replicated to Azure Active Directory and onward to other Office 365 app directories. This work means that changes show up faster, which is good, but there's a small downside to note.

Adoption and Change Management: Two Sides of the Office 365 Card

by Tony Redmond

Adoption and Change Management are often discussed when companies move to cloud services, including Office 365. How quickly can we adopt the new services and how can we manage change? As it happens, Microsoft is extremely interested in driving customer adoption, so much so that this can cause problems with change management simply because so much change happens so quickly insist Office 365. As we discuss here, a structured approach to change management helps.

Microsoft Gives Exchange 2010 Nine More Months

with 2 Comments by Tony Redmond

In a surprising but welcome announcement, Microsoft moved the end of extended support for Exchange 2010 to October 2020. This version of Exchange was the most technology-rich and significant in the product's history, which might be the reason why so many organizations still depend on Exchange 2010 for email. Better options exist, and Exchange Online is the natural place to go... if your network and applications allow the move.

Is Exchange Online Threatened by Ransomware?

with 4 Comments by Tony Redmond

Some people worry that Exchange Online mailboxes could be compromised by ransomeware and people will be forced to pay BitCoin to decrypt their messages. It's certainly a possibility, but out-of-the-box solutions exist if you're unlucky enough to be infected. That is, if you've done the necessary up-front planning to prepare for the worst to happen.,

Microsoft Deprecating Exchange Online’s Search-Mailbox Cmdlet

by Tony Redmond

Microsoft has started to flag its intention to deprecate the Search-Mailbox cmdlet. It's probably the right time to remove this cmdlet from Exchange Online because Office 365 compliance searches can serve the same purpose. At least, compliance searches can do most of what Search-Mailbox does faster. Some functionality gaps need to be filled before we can bid adieu to Search-Mailbox, but its time is coming.

Controlling Communications Inside Office 365 Tenants with Information Barriers (Part 1)

by Tony Redmond

Office 365 Information Barriers allow organizations to erect logical firewalls between different user communities to ensure that regulatory and legal requirements are met. Teams and Exchange Online support Information Barrier policies, which replace Address Book Policies. Some work is necessary to get Information Barriers set up. We cover that work in this article and prepare the ground for deploying the policies to Teams.

The PowerShell Mess in the Microsoft Cloud

with 1 Comment by Tony Redmond

PowerShell is a great way of automating common administrative Office 365 operations. That is, if you know what module to use and how to use the cmdlets in that module. Unfortunately things are a bit of a mess with too many modules and inconsistent behavior in areas like error handling. With so many development groups working on Office 365, the PowerShell situation might be inevitable, but it needs cleaning up.

MyAnalytics Focused on Outcomes not Raw Statistics

by Tony Redmond

The new version of MyAnalytics is available to Office 365 E3 and E5 users and takes a different approach to the interpretation of data gathered about user work activities inside different apps. Instead of telling you the raw counts of messages sent and read and other data, MyAnalytics gives insights to help people work smarter and achieve a better work-life balance.

How Retention Impacts Office 365 Storage

with 3 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.
