A few weeks ago, I ran into an issue with a customer. Scenario:
- Customer had configured alternate-id sign in with AAD Connect (the gist is that it flows on-premises mail to cloud UPN)
- Synced identity to tenant
- Tenant did not have any verified domains
As expected, without a matching verified domain in the tenant, UPN suffixes in the tenant were actually set as @tenant.onmicrosoft.com. … [ Continue reading ]
As you may have figured out from the title, I’ve got a guest post today. Jorge Lopez is a Premier Field Engineer, and has spent a lot of time in the trenches with Windows, AD, and Azure AD, and currently works helping customers resolve hybrid identity issues. … [ Continue reading ]
Right before sending a customer the link for the tool, I decided to test it and noticed that I encountered an unexpected credential prompt. I updated the parameter name, and then added a new feature as well–a test to see if your tenant has the correct licensing to enable Password writeback. … [ Continue reading ]
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 ]
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 ]
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:
Please don’t call Premier asking for support on this.… [ Continue reading ]
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 ]
It’s that time of the year again! I’ve expanded upon an existing feature in the AAD Network Test Tool.
One of the prerequisites listed on the AAD Connect support page is to ensure the Turn on PowerShell Transcription GPO is set to Not Configured. … [ Continue reading ]
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 ]
It’s Two-fer Friday. I don’t know if it was a thing, but it is now.
Based on received feedback, I have updated the AAD Connect Advanced Permissions tool to check for the Active Directory schema version in addition to the Exchange schema. … [ Continue reading ]
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 ]
Yes, Hell has frozen over. The cows have come home. The lady of size has sung.
I have come up with a “best case” solution for the Office 365 hybrid group write-back problem.
For the long(er) background, you’ll probably want to go see this post.… [ Continue reading ]
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 ]
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. … [ Continue reading ]
Update (7/24): I updated this since the last revision, so if you downloaded it prior to 7/24/2018, get the newest version.
I began working with the product group on rolling in some of the network connectivity and testing checks available in the AAD Connect Network Test tool into the actual AAD Connect product. … [ Continue reading ]
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 ]
Over the last couple of days, I’ve updated a few tools that I have published on the gallery. Here’s the run-down:
AAD Connect Network and Name Resolution Test
I’ve been busy with this tool a lot lately, both adding tests and tweaking the way things are done. … [ Continue reading ]
A few users reported bugs with logging that I have updated. There was also an unreported bug when searching the XML generated by Get-ADSyncServerConfiguration for the connector’s AD user, which I have also resolved.
You can get the updated tool at https://gallery.technet.microsoft.com/AD-Advanced-Permissions-49723f74.… [ Continue reading ]
Update: We now have some public documentation available for this as well, so be sure to check there, too! https://docs.microsoft.com/en-us/azure/active-directory/fundamentals/active-directory-deployment-plans
Imagine this scenario: You’ve been running Active Directory Federation Services (AD FS) since before it was cool, and you’re tired of maintaining that highly available infrastructure (at least 4 servers) and the whole federation thing and its myriad of quirks and drawbacks and headaches (such as alt-id (which is still supported in Pass-through authentication with some caveats, listed below), claims rules, certificates, and the fun of trying to change UPN suffixes from one federated UPN to another).… [ Continue reading ]
I have created a more detailed example of how to do this here: https://www.undocumented-features.com/2018/09/14/fixing-office-365-anonymous-group-write-back-and-external-delivery/
Office 365 Groups are glorious creations. There are, however, some instances where they don’t work as you anticipate (or hope). One of those scenarios is when you are configured in hybrid coexistence with the following scenario:
- Office 365 Group Writeback is enabled (for configuring permissions, see this script)
- RequireSenderAuthenticationEnabled is set to False for an Office 365 group
- Your organization’s MX record is configured to point on-premises
In this scenario, external emails sent to Office 365 groups (via your organization’s MX record pointing on-premises) will be returned with one of our favorite NDRs:
“You do not have permission to send to this recipient.”
This happens because the RequireSenderAuthentication attribute (which maps to msExchRequireAuthToSendTo) written to the synced group object is set to the constant True inside of AAD Connect (as shown in the rule “Out to AD – Group SOAInAAD”):
Which translates to this on written-back group objects:
In order to fix this, you need to either update the rule (Edit | Disable and Make a Copy) or update the msExchRequireAuthToSendTo attribute on the synced group objects if you are keeping your MX pointed on-premises, or update the MX to point to Office 365.… [ Continue reading ]
