The hosting venue has changed to serve you better.
Hi, everyone!
In a previous post, I built a function on how to get an MD5 hash from a file stored in memory. I had a particular need this holiday season to compute a hash of a text input string, so I thought I would share my solution with you:
Function Get-HashFromString($String)
{
$md5hash = New-Object -TypeName System.Security.Cryptography.MD5CryptoServiceProvider… [ Continue reading ] 
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 ]
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 ]
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 ]
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 ]
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 ]
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:
Just a quick note–if you use this tool, I’ve updated its logging output (though not the tool itself).
Also, I’m always open to suggestions on how to make it better!
You can download the latest version from the PowerShell Gallery: https://www.powershellgallery.com/packages/Get-PublicFolderIDFixReport/2.3.2… [ Continue reading ]
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 ]
While hammering out a script for one of my customers today, I decided that it would be a nice touch to upload a log file (that I’d handily built with this function) to their SharePoint team site.
What could go wrong?… [ 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. The premise was quite simple: monitor the Teams log file for an incoming call entry and then send the Teams hotkey sequence to answer.… [ 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.
As we encounter more and more customers still working remotely, helping enable them use the most modern tools (like Microsoft Teams) is critically important. … [ 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 ]
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.
You can quickly see what the endpoint is showing available by using this function:
Function Test-MigrationEndpointAuthentication($Url)
{
# Build URL
$Url = $Url.TrimEnd('.').TrimEnd('/').TrimEnd('.')… [ Continue reading ] 
Sometimes, you just get too much stuff, and you need to filter it.
It’s true in life, with YouTube cat videos, and with M365 Content Search.
In this post, we’ll talk about using the FolderId parameter to include/exclude mailbox folders in a content search. … [ Continue reading ]
