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 ]
Nearing the height of the COVID pandemic here in the U.S., I bashed together a script to help customers auto-answer Teams calls with video. You can find the original here: Auto-Answer Teams Call with Video and PowerShell.… [ Continue reading ]
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.… [ Continue reading ]
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 ]
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 ]
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.… [ Continue reading ]
While updating the my Public Folder IDFix tool, I was testing the [
Net.Mail.MailAddress] class. I’ve used it in the past, and it seemed to be a pretty simply way to check for valid addresses, but I started running into problems with it not detecting some things that were obviously not in the RFC.… [ Continue reading ]
Since the TechNet Gallery retirement, I’ve had several users contact me regarding the Public Folder IDFix tool that I put out almost 6 years ago. I don’t do a lot of Exchange Public Folder migrations any more, so I shelved a lot of updates and things that I had planned for my public folder tools.… [ Continue reading ]
In order to help our customers (and their users) fully transition from Skype for Business to Microsoft Teams, I’ve updated the Disable-SkypePlugin script that I published back in 2020 and put it on the PowerShell Gallery.… [ Continue reading ]
A customer I was working with last week had trouble tracking down all the places that an email address was placed in an allow list–across multiple transport rules and other filter policies.
I created a tool just for this back in 2018, but it got lost in the TechNet Gallery decommission. … [ Continue reading ]
Just plodding away here–moved the Get-ActiveSyncDeviceReport script to PowerShell Gallery. What is this script, you ask?
Well, you can use it to export a mailbox’s associated ActiveSync Device IDs–great info to have for documentation, security, or during a migration planning event where you need to populate permitted devices.… [ Continue reading ]
This week, I was helping someone troubleshoot authentication issues when hybrid migration mailboxes to Exchange Online.
In order to migrate a mailbox successfully, the EWS endpoint virtual directory should have NTLM/Negotiate authentication method available.… [ Continue reading ]
As I mentioned in my previous post, I’ve been trudging towards migrating the 60 or so tools, modules, and scripts I published on the now-retired TechNet Gallery over to the PowerShell Gallery.
I want to make sure I migrate the things that people find most useful–so far, I’m about halfway and wanted to do a quick check-in:

Let me know what tools you’re looking for and I’ll prioritize getting those up!… [ Continue reading ]
Post Technet Gallery requirement, I’ve been slowly going through my tools and updating them for the PowerShell Gallery. I came across this tool I built for troubleshooting a deployment at a customer a few years ago and immediately dove into updating it with new endpoints.… [ Continue reading ]
