Now that my account has fully provisioned let’s login and make sure we can actually send and receive emails with the default configuration.

Ok so yup we can send and receive email in this newly minted Office 365 Tenant.

The journey to a Microsoft Hybrid Cloud can be a daunting task for the IT Pro.

Here is an illustration from Microsoft of what this can look like:

This blog series will focus on only Microsoft Exchange. In future Blog series, we will look at the other components such as Skype for Business, SharePoint Online, Azure PaaS, and Azure IaaS.

Our next step will be to setup some User Syncs from our internal Active Directory.

Perform the following steps to install and configure DirSync before you synchronize on-premises Active Directory user accounts to Office 365.

  1. Log into Office 365 Portal with your administrator account. I will do this from my local Domain Controller as that is where I will install Azure AD Connect anyways.
  2. From the Dashboard screen, select Active Users, select Directory Syncronization

  1. In Directory synchronization click Go to the DirSync readiness wizard

  1. On the Office 365 Setup page, Select 51-250, and click Next

  1. On the Sync your local directory with the cloud page, click Next

  2. On the Let’s check your directory page, click Start Scan.

  • On the Find your on-premises domains page, click Next


  • On the Get your domains ready page, click OK, I’ve added and verified all my domains


  • On the Clean up your environment page, Click Download and run IDFix to look for problems in your directory

  • Download the IDFix DirSync Error Remediation Tool and run it the installer

  • Once downloaded extract IdFix.exe

  • Click OK, on the IDFix Privacy Statement popup window

  • On the IdFix tool, click on Query, then click on Accept, then click on Apply.
  • Repeat this process until all errors are gone, you may have to delete some of the orphaned objects.

  • The screen shot below is a 2nd run after all the attributes didn’t get cleaned up the first time.

  • Once working properly when you hit Query it should not return any results.

  • Return to the Azure AD Connect window, and on the Run Azure Active Directory Connect page, click on Download

  • Download and install Microsoft Azure Active Directory Connect

  • On the UAC popup click Yes

  • On the Welcome to Azure AD Connect page, agree to the license agreement and click Continue

  • On the Express Settings page click on Express Settings

  • On the Connect to Azure AD page, type in your credentials with Office 365 Admin rights

  • On the Connect to AD DS page, type in the name of a Service Account with Enterprise and Domain Admin rights, and click Next

  • On the Azure AD sign-in configuration page, verify that your domain name is listed and verified. This pulls from the AD Forest that you are connected to and lists all the UPN’s associated with that forest.

  • On the Ready to Configure page, select the Exchange Hybrid Deployment checkbox and click Install

  • While the initial sync is running return to the Office 365 Admin Center and note that there is a new account called On-Premises Directory Syncronization

  • Once the Synchronization is complete you will see the screen below and click exit

  • Go back to the Office 365 Admin Center and verify that you now have all of your Active Directory users synchronized. The users with a Blocked Status are disabled objects in Active Directory.

    Well that’s all for tonight folks.

    Happy Learning,
