Decommissioning the last Exchange server

When you are in an Exchange hybrid configuration and you have migrated the last Mailbox to Office 365, you might wonder what to do with the last (couple of) Exchange server that is still running on-premises. Can you decommission your last Exchange server because all your Mailboxes are in the cloud? From a supportability point of view the answer is still “No, you can’t decommission the last Exchange server because you need it for management purposes” and most customers think this is disappointing. Let me explain why we still need this last Exchange server.

Securing Exchange Servers

Securing Exchange servers is hard. I mean it can be a giant pain sometimes. There are what, hundreds of millions or maybe billions of lines of code running on your Exchange servers, right? It doesn’t take much for a typo to get through and open a vulnerability that can then be exploited opening the most important and valuable data within your organization to all kinds of bad actors.

Thinking about Exchange 2019?

In October of last year Microsoft released a new version of on-premises Exchange server. Here at the ENow's Solution Engine blog, we realized we had a lot we could cover. Normally I focus mostly on writing about Office 365 and Azure features and updates, but I think there is still room in the blog-o-sphere for a post about on-premises software too.

Since Exchange 2019 came out almost 3 months ago, I don’t see a lot of point in doing another blog post that lists “What’s New in 2019.” I’m going to try a slightly different approach here and assume that you’ve had a chance to review the new features in Exchange 2019. If not,

The Curious Logic Behind Some EOP Routing Decisions

Recently, one of my customers reached out to me stating they were having trouble delivering emails due to SPF failures. While it’s not uncommon for SPF checks to fail (you don’t want to know how many organizations struggle implementing SPF records correctly!), I was a little surprised. After all, the customer had successfully implemented SPF records for quite some time now, and rarely ran into issues with it. In fact, they are quite the example for some of my other customers as their SPF policy is set to a hard failure. Needless to say: a lot of effort went into it, to ensure their SPF records were correct/up-to-date/etc. However, that's not the point here. What follows is an overview of what we've discovered during our troubleshooting. To me, it revealed some interesting routing logic in EOP –some of which is barely (not) documented.

Office 365, The Last Seven Years, and the Future of Exchange

At a recent Exchange MVP panel discussion at Ignite 2017, a question came up that I’ve been asked at previous panels. The spirit of these questions were around the future of Exchange Server On-Premises in relation to Office 365. Will there be another on-premises Exchange Server version? If so, how will its features stack up against Exchange Online? What role will Exchange Administrators play in the coming years? I wanted to share my thoughts and experiences on this topic, as it appears to be one keeping many Exchange Server Administrators and Consultants up at night.

What Does “Supported” Mean to Microsoft?

There are a few words Microsoft likes to use in several different situations. “Federated” is a great example of this. Federated can mean several different things in the Microsoft world, and it can sometimes be hard to tell what sort of “federation” you’re talking about.

“Supported” is another word Microsoft uses to mean different things in different situations, and what I’d like to talk about in this blog post.

Office 365 Security & Compliance Center – Part 2

Office 365 is a collection of online services that allow organizations to use Exchange, Skype for Business, and SharePoint in the cloud. In the nearly five years that Office 365 has been available most of the organizations using Office 365 have used it just like that; for Exchange or Skype for Business or SharePoint in the cloud. Some organizations are using more than one of those services, but for the most part they are still using them separately.
