Update to AAD Network Communications Test Tool
Right before sending a customer the link for the tool, I decided to test it and noticed that I encountered an unexpected credential prompt.

Update to AAD Connect Network Test
While troubleshooting an issue for a peer today running the Exchange Hybrid Configuration Wizard, I suspected that the environment might have an authenticated proxy in the way. So, I dug out some code I used in the AAD Connect Network Test for Invoke-WebRequest.… [ Continue reading ]
Add legacyExchangeDN as x500 proxy address from a remote forest
The other day, on one of the forums, I came across an issue that I also had with one of my customers a few years ago. In my customer’s instance, they had imported thousands of contacts into an externally trusted forest and deleted them in their primary forest (which then removed the objects from Office 365). … [ Continue reading ]
AAD Connect, a dedicated resource forest, a custom connector, and a bunch of transform rules: a GalSync story (Part 2)
In part 1 of our adventure, we built an Azure AD lab to support configuring AAD Connect to work as a GalSync engine. In this post, we’ll finish up the configuration. As a reminder, this is the what the overall solution will look like:

And, as I mentioned in part 1:

AAD Connect, a dedicated resource forest, a custom connector, and a bunch of transform rules: a GalSync story (Part 1)
A few years ago, I worked with one of my close consultant peers to build a GALSync-style solution for a big state government that was going through a divestiture from a single BPOS-D (yes, I am old) and a single managed hosted Exchange environment to multiple O365 multi-tenant instances. … [ Continue reading ]
Update to the AAD Network Test Tool

Sync Custom Attributes to Office 365 for Group-Based Licensing
This feature is an “oldie but goodie” that my customers are starting to ask questions about as they start looking into ways to automate their Office 365 deployments.
Can I sync additional attributes to Office 365, and can I use them for Group-Based Licensing?… [ Continue reading ]
Update: AAD Connect Advanced Permissions Tool

Update: AAD Connect Network Test Tool
Just a quick note: I’ve updated the AAD Connect Network Test Tool to now query Windows Product Edition data to provide a little more system configuration prerequisite testing information, based on the OperatingSystemSKU data listed at https://docs.microsoft.com/en-us/windows/desktop/CIMWin32Prov/win32-operatingsystem.… [ Continue reading ]
Fixing Office 365 Anonymous Group Write-back and External Delivery
Yes, Hell has frozen over. The cows have come home. The lady of size has sung.
I have come up with a “best case” (ok, maybe “better case”) solution for the Office Microsoft 365 hybrid group write-back problem.
Background
For the long(er) background, you’ll probably want to go see this post.… [ Continue reading ]
Update to the AAD Connect Remove Proxy Addresses Script
This week, while working with one of my customers in a custom Office 365 deployment, I had the opportunity to revisit and update one of my scripts (Remove Proxy Addresses via AAD Connect). I had originally built that script for a large state government Office 365 migration from BPOS-D. … [ Continue reading ]
Update to the AAD Connect Advanced Permissions Tool
Woo! A day of updates! I’ve made a few updates to this tool, so hopefully you’ll find them useful:
2018-08-12: A reader noticed that the UpdateAdminSDHolder switch didn’t work ask expected when specifying the ExchangeHybridWriteBack OU without the ExchangeHybridWriteBackOUs parameter. I have found and updated that! … [ Continue reading ]

Update: AAD Connect Network and Name Resolution Test
Update: This tool has a new shortlink: http://aka.ms/aadnetwork
Since the tool passed the 500 download mark a few weeks ago, I’ve started getting more questions (internal and external) about a few of the tests and checks. So, I decided to update/refine them to hopefully provide better guidance.… [ Continue reading ]
