Office 365 – Unable to Activate Directory Synchronization

Between demos, trials and actual production environments, I’ve probably activated Directory Synchronization on a couple hundred tenants at this point. The process is pretty non-eventful, you add a domain, validate it and click the button that says “Activate”; then it’s on to the fun stuff. Just when you start to feel like you’ve seen just […]

Office 365 – Script to Change UPN between Federated Domains

Nothing too fancy in this post, just a quick script that can help make a nuisance of a task easier… There’s been a long-standing issue with Office 365 where you cannot change a user’s userPrincipalName (UPN) from one federated domain to another. As an example, if you have federated the domains “company-a.com” and “company-b.com”, changing […]

Office 365 – Why You Need to Understand ImmutableID

As part of planning for your identity with Office 365, it’s important to understand the concept of the “ImmutableID”. By definition, “immutable” means “unable to be changed” which should be sufficient warning that this is something you need to take time to plan properly.

Office 365 – Azure AD Sync: Did You Know?

It’s been about six months since “Azure AD Sync” (often called “AADSync”) was made generally available with the intended purpose to replace the previous DirSync tool. In addition to an overhaul under the hood, AADSync brought with it new features such as support for multiple Active Directory forests. If you’re configuring Directory Synchronization for the […]

Office 365 – The Limitations of Alternate Login ID

Back in April of 2014, Microsoft announced a feature called “Alternate Login ID” (sometimes referred to as “Alternative Login ID”). The idea was that instead of changing the UPNs in your on-premises Active Directory, you could use a different value to authenticate to Office 365 and sync that value to the cloud as your login. […]

Office 365 – How to Configure UPN Filtering in AADSync

Azure Active Directory Sync Services (AADSync) was made “generally available” in September 2014. While the old DirSync tool is still available (and actually still linked to in the portal), AADSync should be what you’re looking to deploy at this point. As we make this transition, there is a learning curve in trying to understand how […]

Office 365 – Using Password Sync as a Backup to AD FS

For organizations that deploy AD FS for single sign-on with Office 365, it is as critical of a component as their on-premises Active Directory. While you may have your mailboxes residing in Exchange Online in the cloud, if your on-premises AD FS is not available, users cannot authenticate to access their mailbox. There are a […]

Office 365 – Assign Licensing “User Location” via Active Directory

The first time you assigned an Office 365 license to a user, you likely used the portal as opposed to PowerShell. There’s also a good chance you saw the error message below: Organizations populate Active Directory user objects with varied amounts of data. In many organizations, especially global organizations, the “Country” field is populated in […]
