Changes to hot recipients throttling in Exchange Online

I expect we all know there are limits to what you can and cannot do with your Exchange Online mailbox. We all know there is a limit to how many emails you can send and receive, how much storage you can use, how much data you can move into or out of Exchange Online, and how big each individual email can be. However, I find that few Exchange Online administrators know exactly what those limits are, how they work, why they are there, or what you can do about them.

Microsoft is currently in the process of enforcing some of these limits that have not previously been enforced. I thought this would be a good time to go though the limits that are in place for your Exchange Online mailboxes, and what you can do if you find yourself in a situation where those limits are negatively impacting your organization.

RBAC in Exchange Online Part 2 - Scoping admin roles

In the first article in this series, I coved the basic GUI based ways that you can use RBAC in Exchange Online to allow users to control their own contact information in Exchange Online and to allow you to designate administrators with limited sets of rights.

In this article, I’m going to show you how to really use RBAC. We’re going to dive into PowerShell and see how to do things like give an administrator rights to manage a specific sub-set of your users.

RBAC in Exchange Online - Part 1

A common request I get while doing migrations into Exchange Online is to assist customers in setting up permissions so that they can limit administrator's rights and scope to control Exchange Online. The solution for this problem is Role Based Access Control (RBAC), and it can be a little confusing to setup.

In this article I am going to start into the easier, GUI based options for setting up RBAC in Exchange Online. If you're looking for the more advanced RBAC controls, skip ahead to Part 2.

New Exchange hybrid troubleshooting tool

Anyone who has ever done an Exchange Online hybrid deployment can tell you that process can be frustrating. Before the Hybrid Configuration Wizard the process was long and complicated with too many steps and too many places to make a small mistake. With the advent of the HCW the process became much more of a “black box” where the guy doing the deployment really didn’t know what configuration changes were being made, so misconfigurations became very hard to troubleshoot. Add on top of all that the fact that you, and the person doing the deployment really have no control or visibility into the Microsoft side of thing, and a hybrid deployment quickly turns into a difficult task.

Changes to off boarding from Exchange Online

When I migrate customers to Exchange Online I always recommend they maintain an Exchange hybrid server. There are several reasons for this recommendation; it’s much easier to manage SMTP addresses with an Exchange server on-premises, and it’s much easier to get your mailboxes back out of Office 365 if you maintain a hybrid server. To me, one of the great advantages of Office 365 is that I have never felt Microsoft was trying to “trap” customers in the service. They have always made it fairly easy to move mailboxes in and out of Office 365.

Forcing a manual DirSync
Forcing a manual DirSync

Remember the old days (by which I mean last week) when the process to force a DirSync to run from your DirSync server was to run the .\DirSyncConfigShell.psc1 then you could access the Start-OnlineCoexistenceSync  commandlet? Well, Semper Gumbi (pseudo-Latin for “always flexible”) faithful readers because things have changed.

Exchange Online and the staged migration

I do a lot of Exchange Online migrations. I’m not really sure how many I have done, but I would guess the number is between 50 and 100 over the last 3 years. Over 90% of those migrations have been Hybrid. In fact, I’m pretty sure only one or two of those migrations have not been hybrid. Recently I had occasion to do a staged migration. I’d like to go through that process and discuss why I ended up making the choices I did.

Self Service Password Reset writeback to Windows Server AD using DirSync

As soon as I heard about password sync for DirSync, my first feature request was password write back. It’s been just about a year since password sync capabilities were added to DirSync and how we have password reset writeback available in public preview. There are a couple of caveats that we need to cover, but for the most part this feature is here and ready to go.

Setting up 2 factor authentication for Office 365

Recently Microsoft has enabled 2 factor authentication for all Enterprise Office 365 tenants at no additional cost. Their offering is based on PhoneFactor’s 2 factor authentication system, a company Microsoft bought a couple of years ago. Setting this feature up for Office 365 accounts is fairly easy, but there are a couple of “tricky” parts that could use a bit of clarification so I thought I would run through the process for you here.

Notes from MEC: Exchange Multi-Org Hybrid

I’m going to do a series of blog posts going over some of the things we learned at the Microsoft Exchange Conference this year. For me, the number one thing I got from MEC was Microsoft’s announcement that they now support Multi-Org Hybrid deployments done by civilians (non MCS/ACS deployments). By “Multi-Org Hybrid” we mean connecting multiple Exchange on-premises organizations to the same Office 365 tenant. I’ve had several customers asking for this deployment for years now, so it is a great boon for me to be able to do these deployments now.
