It’s well-known that our Government Community Cloud instance of Office 365 doesn’t support emailing a channel. This can be problematic when you are attempting to schedule a channel meeting and include recipients not on the platform. What ends up happening is the recipient can actually receive an NDR (because they can’t send the meeting acceptance back to the channel).… [ Continue reading ]
Update to AADConnect Network Communications Test
Hey!
It’s been a while since I’ve updated this tool. One of my peers, Didier Akakpo, pointed out that we have a new endpoint to add for Self-Service Password Reset Writeback.
As such, I’ve updated the tool to include this endpoint under $OptionalResources for Commercial and GCC-Moderate tenants.… [ Continue reading ]

Content pulled back from the memory hole
I decided to go for a walk down nostalgia lane–while I love to talk about new stuff that we’re doing here at Microsoft, I also like to reminisce about the earlier times in my career–especially when I first started tech blogging.… [ Continue reading ]
Tern around: Concise PowerShell Ternary Operators
I’m writing this down because…

I will forget it.
I was reviewing someone else’s code that was largely full of common if/then statements and then stumbled across a solitary instance of a ternary statement.
It took me a while to decipher since the ternary evaluation happened as an argument for a cmdlet–definitely limiting its readability. … [ Continue reading ]
Update to Find-DuplicateValues script
Hey! As we enter the waning days of summer, I wanted to update a tool that I’ve had sitting around for a while.
Years ago, when I was in Microsoft Consulting Services, I ran into one particular customer that had manually populated the mail property of thousands of service accounts, groups, vendor accounts, and contacts–not with the object or user’s individual email address, but with the email address of the person who managed the AD object. … [ Continue reading ]
Update: AAD Connect Test Tool Updated
We’ve updated our baseline requirements for deploying AAD Connect, so I’ve updated the AAD Connect Network Communications Test to reflect those changes.
Key changes:
- We now allow you to configure AAD Connect using the Hybrid Identity Administrator role, so the tool now checks for it.
A Deep(er) Dive into Teams Architecture
While working on my current book, I was thinking about a deeper exploration of how Microsoft Teams handles permissions and content. One of our Sr. Customer Engineers has a fantastic (and very expansive) diagram of the moving pieces, which I’ve adapted to fit here.… [ Continue reading ]
Configuring “employeeId” with Set-AzureADUser
While working on a project for a customer, I noticed that the didn’t have a way to correlate “uniqueness” between guest identities that they create and a source of authority system. I wanted to explore using the employeeId attribute in Azure AD as a way to set this data.… [ Continue reading ]
Keep calm and SendAs a Proxy Address
I’m gonna channel the great Etta James:
Ok, I’m back.
I’ve been waiting for this feature for what seems like an eternity–the ability for a mailbox that has multiple proxy addresses to send from any of those addresses.
Background
As most of you probably know, a mailbox can have a whole lot of additional SMTP addresses associated with it (a mailbox can have up to 400 proxy addresses stamped on it). … [ Continue reading ]
Export all SSID/Network Profiles with Passwords
After I re-posted a quick script to export all of the Windows Vault credentials, one of my good friends, Aaron Steele, threw down the gauntlet:

To that, I say …

Yes, it’s rushed and messy (and has a couple of quirks), but gauntlets have to be responded to quickly and all.… [ Continue reading ]
Requiring multifactor authentication for all Teams users not on trusted networks
This week, I’m exploring some of the basics of Conditional Access and using it with Microsoft Teams.
In the “legacy” world (the term we attach to most things that aren’t bleeding edge these days), we typically saw organizations build the high, high walls and dig the deep, deep moats (and occasionally fill them with alligators) to keep the bad guys out.… [ Continue reading ]
Resolved: Error: A special Rpc error occurs on server [servername]: The source data is corrupted or not properly Base64 encoded
Friday, while building a new lab to use while writing a chapter for our new Microsoft Teams book, I went through the normal process in Exchange to request a certificate and apply it. Easy peasy normally, right?
It should have been. … [ Continue reading ]
Update to AAD Network Communications Test
It’s literally been a year since I’ve updated it–mainly because we haven’t made any significant endpoint changes.
I did detect some CRL endpoint updates and a few other odds and ends for Worldwide Commercial and GCC Moderate, so I’ve updated the AAD Network Communications Test tool accordingly.… [ Continue reading ]
Update to Get-PublicFolderIDFixReport
Hi! Just a quick note to let you all know I’ve updated the email validation function for the Get-PublicFolderIDFixReport tool used when verifying mail-enabled public folders. I used the formula from my previous post. 🙂
If you have ideas on how to make this tool more useful, please let me know!… [ Continue reading ]
