Disable Skype SKUs across all users

This week, I was presented with a question from a partner who was in the middle of the Skype for Business portion of a larger merger and acquisition migration project. The customer had enabled the Skype for Business license for all users in the tenant (including users who hadn’t migrated for other domains and forests), and since neither the hybrid configuration nor DNS were complete, messages and calls were undeliverable. … [ Continue reading ]

Office 365 Administration Inside Out

I meant to post this earlier, but I wanted to let everyone know that I’ve had the great honor of being able to write a book with some of the titans of Microsoft Consulting Services.  The book has all new content for Office 365 based on our experience in the field, and even features current service release updates. … [ Continue reading ]

Troubleshooting Mailbox Migration Error “You can’t use the domain because it’s not an accepted domain for your organization.”

While migrating users via MRS between organizations (especially to Exchange Online), a pretty common error that I run across is:

You can’t use the domain because it’s not an accepted domain for your organization.

This error is generated because the MailUser object of the user you’re attempting to migrate has a proxy address attached to it that is NOT an accepted domain in your target organization or tenant.… [ Continue reading ]

Export and Import Calendar Processing Information

During my current project, it became necessary to capture additional calendar processing parameters that are not preserved during a normal hybrid move–such as booking policies.

Some of the challenges that I faced with this tool:

  • Blank or unpopulated attributes
  • Conversion of sAMAccountName values to PrimarySmtpAddress
  • Multiline attributes with special characters
  • Attributes that were set for the wrong recipient type

So, the first thoughts I have when building a tool generally involve four concepts: what data do I need to gather/export, what format is the source data, what format do I need to save it in, and how do restore/import that data back into the target?… [ Continue reading ]

Create a Transport Rule to Reject a Message When Both Domain Conditions Are Met

Today, I saw a question come up as to how to block a message when it’s sent to two different classes of users at the same time.  Let’s say you want to be able to send to John@domain1.com, Bob@domain2.com, and Jane@domain3.com (list 1) or to Mark@domain4.com, Sue@domain5.com, and Mary@domain6.com (list 2), but any time those users from both list 1 AND list 2 appear in the To/CC of the *same* email message, you want it to be blocked. … [ Continue reading ]

Use AADConnect to add a Proxy Address

* UPDATE* After doing this originally, I decided to take a different route and write it back to the on-premises AD, so that way, the objects are synchronous.  This post now reflects the updated content.

A few weeks ago, I had an issue where I needed to remove a proxy address from the proxyAddresses array of a user being synchronized to Office 365. … [ Continue reading ]

Remove an unwanted ProxyAddress pattern from users via AADConnect

I had an interesting request from a customer the other day where they were synchronizing Active Directory into two disparate environments–Office 365 and another hosted Exchange environment.  In their new Office 365 environment, they didn’t want any address proxies matching a particular pattern to be part of a user’s proxyAddress array–BUT–they also didn’t want to remove them from their on-premises accounts since they are being used by their other hosting environment as an application routing address.… [ Continue reading ]

Office 365 License Assignment

There is perpetually a lot of angst around licensing users for Office 365 workloads.  Most of my customers over the years have wanted to ease into deployment, only enabling certain services at a time.  Of course, as an evergreen service, we are always adding features, leading to new service plans to disable as you discover them.… [ Continue reading ]

Using XML to Backup and Restore Office 365 Settings

Frequently, I am asked to make changes to a customer's environment.  I'm a belt and suspenders kind of guy, so my backups have backups.  At any rate, normally when I am performing changes in a tenant (or Exchange on-premises environment, for that matter), I make two sets of backups–one by piping a Get-cmdlet to Export-CSV (so I have a readable copy), and one by piping the same Get-cmdlet to Export-Clixml (so I have a way to set the nodes as parameters and import them back).… [ Continue reading ]
