M365 - Exchange Online Center

Moving to Office 365 means a pretty big adjustment. Administrators who were used to doing things one way are going to have to make adjustments as their organizations migrate their infrastructure into Office 365. One of the areas where new Office 365 administrators often feel most in the dark about is changes in their environment.

Only a statistician loves statistics and I am no statistician. However, it’s interesting to try to track the growth in Office 365 numbers based on the snippets of information released by Microsoft in their financial results and elsewhere.

Spam is the bane of all messaging administrators, as well as a major pain for all email users. Using email means a consistent battle against spam, malware, and unwanted nonsense flooding your inbox. There are a number of different tools and tactics we, as administrators, can use to reduce the impact of these attacks and recently Microsoft has added another one to the toolboxes of Office 365 customers. In this blog post I'm going to explain what DKIM is, and how you can use it to help make the world a safer place for legitimate email messages.

A little over two years ago, I wrote about an issue I encountered with a KEMP load balancer and how Microsoft performs hybrid mailbox moves. More specifically, the issue evolved around a seemingly different interpretation between KEMP and Microsoft regarding the implementation of the expect 100-continue header. As I noted then, the workaround was to configure the KEMP load balancer to ignore the 100-Continue rules as described in RFC 2616.

Over the past few years, Microsoft has made many attempts to do away with public folders. If are still working with Exchange 2007 and Exchange 2010, I’m sure you’ll remember the many rumors about Public Folders being deprecated in “vNext”. Yet, they still exist today in Exchange 2016 –although not in exactly the same form as in earlier versions of Exchange.

Directory-Based Edge Blocking (DBEB) is a feature in Exchange Online Protection which automatically blocks email messages sent to recipients that do not exist in the Office 365 tenant. By default, DBEB is enabled for every domain in the tenant.

Hybrid environments are complicated. Microsoft has done tons of work over the years to try to simplify the hybrid experience—a huge task when you remember that hybrid Office 365 deployments can cover Active Directory, Exchange, SharePoint, and Skype, along with cloud-only services such as Office 365 Groups.

…that Mailscape 365 includes latency trending reports which allow you to monitor and report on connection latency and end user transaction times?

In Windows 10, Microsoft introduced “Windows Hello” which – to keep things simple – offers the ability to use biometrics to unlock a computer instead of using a regular password.  But the fact that you can use biometrics for authentication purposes is not really new. Given this, you might wonder what is so special about Windows Hello. The answer lies in the combination of Hello with another feature.

The functionality in Exchange Hybrid is now quite mature. It’s been available since the launch of Office 365 (or even before if you include the embryotic support in Live@EDU) and provides the rich co-existence functionality that allows organizations to mix mailboxes on-premises and in the cloud, retaining much of the normal sharing capabilities people rely on for day-to-day collaboration.
