Earlier this evening, a former peer asked me about trying to bulk delete items from the Drafts folder on a customer’s Exchange Server 2010. While Microsoft Exchange Server 2010 reached end of support in October 2020, it still will work (though we certainly don’t recommend keeping it around, as it’s no longer receiving regular maintenance, support, or security updates).… [ Continue reading ]
Quick-and-dirty Catch-All Mailbox for GCC Channel Meeting Invitations
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 ]

Removing on-premises proxy address on the way to the cloud
Several years ago, I wrote a script and a blog post to help customers use AAD Connect to strip out proxy addresses during the synchronization process. The goal was to keep the on-premises AD proxyAddresses attribute for users untouched, as it was needed for other applications and communication on-premises.… [ 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 ]

Re-posted Sensitive Information Type XML
While continuing my stroll down old posts lane, I stumbled across one that I made for building custom sensitive information types. One of the things that I noticed about it was that it it had a link a file hosted on our now-sunsetted Technet Gallery.… [ 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 ]
Find and Fix Broken AD Object Inheritance
A few years back, I created a script for a customer to help find broken AD object inheritance during an Exchange migration. I then created a blog post to go through it.
However, time has marched on and the TechNet Gallery fell off the face of the earth, and I needed to update this. … [ Continue reading ]
