A few weeks ago I’ve turned on Cloud App security feature in my Office 365 Subscription. I was surprised today when i started getting the alerts that there were some attempts made to login as my on my account. In less than two hours there were m15 attempts and they were all outside US and from an unknown device. First I didn’t know where it came from but when I logged on the links provided and I re-called that I did setup some policies a weeks ago.

As you can see below there were three email sent to me whenever there was an attempt made to hack into my account

Email Alerts

And here is the policy matched and alert was triggered

 

The Next Step – Review the alert

The next action was to Review the alert and investigate it. I was brought on to this page

 

What did I configure? It was not enabled by default

As I said above I created a policy while ago and based upon that now I’m getting these alerts

As you can see, in GOVERNANCE I’ve options to select the action.

Pro Tip !

Enable Multi-factor authentication

What is centralized transport?

If you already have heavily invested in your on-premise mail gateways and other infrastructure and you plan on moving to Office 365, Exchange Hybrid is the way to go in a long haul. When you have Exchange 2016 configured for Hybrid Setup with Office this where it come. 

So Why Centralized Transport?

It all depends on your business requirements, and if you don’t then you are good with regular setup routing via Office 365 , let’s cloud manage it for you. IF YOU DO HAVE such as regulatory and compliance requirements and even for other purpose where you want you emails MUST  route through your on-premises infrastructure then you need to configure it this way. In this video I will walk you over how does it really work.

Microsoft Teams, does not need any introduction as there is a lot marketing going on 🙂

Team built on core services are Exchange and SharePoint and Skype too. As soon as you create a new Team for collaboration with you colleagues background services start spinning exchange group mailbox and SharePoint libraries for you and in few minutes you are ready to collaborate in real-time which even allows to make calls from any device (I like it on my iOS).

So what is external collaboration and how to control it?

You can invite external parties to contribute and collaborate in Microsoft Teams or to be specific you can invite them in Channels within your team. If you don’t change the default setting, it open to anyone means anyone can send EMAILS your channels once they know the SMTP ALIAS. So if you don’t like it and if you have some business requirement which may not want to you keep it open for all, this video while show you how to control the EXTERNAL SHARING.

Yes this will happen in Jun ’18 release of Exchange cumulative update and after that If your system does not meet requirements which included .NET Framework 4.7.1 it would not allow to you install either exchange 2013 or Exchange 2016.

So make sure in the next few months you do testing in your lab environment and make sure it goes through you change management process (if any) and get the system ready. This is major update. At this point it not clear how or what will happen if you have existing Exchange 2013/2016 without .NET Framework 4.7.1 and new Servers installed after June ’18 with .NET 4.7.1.

I will update this post as soon as I hear back from Exchange product team, till then stay tuned.

Hybrid free/busy lookups fail between Exchange Server 2016 CU8 and O365

Microsoft has identified a condition where Free/Busy lookups from On-Premises to O365 in a hybrid configuration may fail.

 

Symptoms

After you install Microsoft Exchange Server 2016 Cumulative Update 8 (CU8), free/busy queries from Microsoft Office 365 users to on-premises mailboxes in hybrid environments fail if the cloud mailboxes are not archive-enabled.

Cauase

This problem occurs because of a known issue that affects OAuth connectivity in Exchange Sever 2016 CU8.

Workaround

To work around this issue, create personal archive mailboxes for each cloud mailbox.

Status

This problem is scheduled to be fixed in Microsoft Exchange Server 2016 Cumulative Update 9 (CU9). For a supported fix for CU8, contact Microsoft Support.
