I read a great post by Benjamin Armstrong [A] with a one-line Powershell command to list virtual machines in Hyper-V that have a missing or broken VHD disk.
This helped me do some weeding on some Hyper-V machines and clean up old/stale VMs.
get-vm | Get-VMHardDiskDrive | %{write-host $_.VMName.PadRight(40) ":: VHD Exists :: "-NoNewline; Test-Path $_.Path}
Just putting this here for my notes.

Exchange has the ability to limit sending permissions on Distribution Groups. Finding which Distribution Groups have user sending permissions assigned to them can be very time consuming using the portal.
To make it quicker, you can list the accounts that have the ability to send to a specific distribution group using PowerShell.
$FormatEnumerationLimit=-1 # This allows the property to be expanded in format-table
Connect-ExchangeOnline
Get-DistributionGroup -Identity XXX | Format-table -Wrap -AutoSize -property name,acceptmessagesonlyfrom # Change XXX to the Distribution Group SAM account name
I company I work for just completed an O365 tenant migration. After email had been moved to a new Exchange tenant, we noticed that users continued to use their Outlook apps on their phones. They were also continuing to chat on the old tenant's Teams and were using all of the Office apps on the web using their cached logins.
This caused a headache. Some users were in the new environment with the correct domain—others didn't notice the “@onmicrosoft.com” and were having issues with SSO apps that had been migrated.
We needed to revoke all of the cached login tokens force log out all users. This quick Powershell command did the trick:
Connect-AzureAD
$users = Get-AzureAdUser -All $true
$users | foreach {
Revoke-AzureADUserAllRefreshToken -objectID $_.objectID
}
After this runs, all users will be required to log in again. This forced them to go into the new tenant and solved our SSO issues.
Here's a script that I'm using to roll out the Quest ODM agent on PCs in my environment that do not have access to the LAN. I used Atera Service Desk to deploy it for internet-only installation.
This script requires that you download the Device Agent from the Quest Migration for Active Directory downloads page: 
Once that's complete, you will need to upload the file to a publicly accessible file share. I used Azure Files to create a storage container and provide direct access to the file. This URI will be pointed to in the script, so you cannot use something like OneDrive or SharePoint without special configuration.
Before running this script, you will need to change the following XXX values:
$QuestODMMSIURI – This will be the publicly accessible MSI that you uploaded to your file share.Function Invoke-ODM_Agent_Install {
$InstallCheck = Get-ItemProperty -Path "HKLM:\SOFTWARE\WOW6432Node\Quest\On Demand Migration For Active Directory\ODMAD_AD" -ErrorAction SilentlyContinue
If ($null -eq $InstallCheck) {
Write-Host 'Downloading ODM agent.'
$QuestODMMSIURI = 'XXX' # Change to use your own Azure Files URI
$QuestODMdest = 'C:\Temp\ODM\QuestODM.msi'
Invoke-WebRequest -Uri $QuestODMMSIURI -OutFile (New-Item -Path $QuestODMdest -Force)
Write-Host 'Installing ODM agent.'
cmd /c "msiexec.exe /I `"C:\Temp\ODM\QuestODM.msi`" /qn SERVICEURL=https://us.odmad.quest-on-demand.com/api/ADM AUTHKEY=XXX" # Change to use your own authkey from Quest
Write-Host 'Finished installing ODM agent.'
}
ElseIf ($null -ne $InstallCheck) {
Write-Host 'ODM agent is already installed.'
}
Else {
Write-Host 'ERROR!'
}
}
Invoke-ODM_Agent_Install
Call Monitoring or call shadowing is a feature offered by Ringcentral that allows specified users to silently join other users' ongoing calls.
This functionality is desired for training and call center environments and is intended for managers or supervisors to listen in on ongoing calls between agents and external customers.
Before enabling this feature, you must have the following in your environment:
There are two user roles for this workflow that are admin-managed from the Ringcentral web dashboard:
I will refer to the third party callers as “customers” in this guide.
After adding a user to the “Can be Monitored” group, they will receive the following notification email: 
There doesn't appear to be a way to suppress this notification.
Login to Ringcentral with an admin account.
Navigate to Phone System > Groups > Call Monitoring and click + New Call Monitoring
Enter a name for the Call Monitoring group. This will not be displayed to users.
After entering the name, expand the “Group Members” setting. Select at least one user for “Can Monitor” and at least one other user for “Can be Monitored”. (Note: I was unable to have the same user in both categories, so a user seems to only be able to use one or the other): 
Save these group settings and return to the main Ringcentral view.
After the admin stuff has been completed, the manager with the “Can Monitor” role must do the following:
Open the Ringcentral web or desktop app and login with their user account.
Click on the “Settings” icon at the bottom left. Click on “Phone”.
In the “Phone” menu, scroll down to the Heads-Up Display (HUD) section and enable the HUD by flipping the switch: 
Save the settings, accept the notification, and return to the main Ringcentral view.
From the main Ringcental view, click on the “Phone” icon.
Under the “HUD” section, click on “Extensions”. Click on the “Add an extension” button: 
Type the name of the “Can be Monitored” user(s) and then click the Add button: 
After the admin and user changes are made, the “Can Monitor” manager can then monitor when a “Can be Monitored” agent is in an active call using these steps:
The “Can Monitor” user must open the Ringcentral web or desktop app and login using their user account.
Navigate to “Phone > HUD” and join the call by hovering over and clicking on “Monitor Call”: 
From there, there are several tools that the “Can Monitor” manager can employ:
Call whisper: Talk to the “Can be Monitored” agent without the customer hearing.
Call barge: Talk to all parties on the line. This is like a conference call.
Call takeover: Drops the “Can be Monitored” agent from the call, leaving the manager and the customer on the line.
Call recording: Begins a recording session with no notice to the customer or the agent. These recordings are stored in the “Call history” tab in the Phone section of the Ringcentral web or app interface.
Ringcentral requires audio files to be saved as .mp3 files.
To do this, you'll need to convert your audio that you recorded in the Voice Recorder from .m4a into .mp3 using the app Audacity and the ffmpeg plugin. Audacity and ffmpeg are open source programs that can convert audio into different formats. Audacity is the main program and ffmpeg is an extension that Audacity uses to open .m4a files.
Before you'll be able to convert the file, follow these steps to get Audacity and ffmpeg set up on your computer:
After the setup is complete for both apps, follow these steps to convert your audio file:
.m4a file:
After the window closes, your conversion will be complete. You can close Audacity without saving the file.
Navigate to the location where you saved the .mp3 file and upload it to Ringcentral.
I am creating an onboarding/new hire Sharepoint List at one of my clients and wanted to display a column/field only if a box is checked.
To do this, I created two columns:
ReplacementHire = Boolean Yes/No checkbox
PreviousUser = Text field
I wanted the PreviousUser field to only appear if the ReplacementHire box is checked.
To do this, I opened my Sharepoint List and did the following steps:
Click on the New button on the left side of the page.
In the Form view, click on the book/edit icon at the top right and click “Edit columns”
In the popup window, paste in the following: =if([$ReplacementHire] == true, 'true', 'false') From what I gather, the if statement reads, if the box is checked (true), then 'true' (meaning display the field), else 'false' (if not, hide the field).
Click OK and then Save. Refresh the page and test.
There was also some headache in the field/column name. What you typed in originally for the column name will be the “anchor” or name in the URL.
To get this anchor, do the following:
Navigate to the Sharepoint site, click on Site Contents.
Find the form, click on the three dots, and click Settings.
On the Settings page, click on the column title under the Columns section.
On the Column setting page, check the URL in your browser for anything after &Field= This info will be the “anchor” that you use for the =if([$anchor] == true, 'true', 'false') in the Conditional Format window.
Just putting this here for my future reference.
If you're setting up a phone or faxing system, you're going to need to make test calls and faxes to verify that things are working.

A company I'm working with is using a Neat Bar [A] and Neat Pad [A] for Zoom calling. They also use Meraki network devices for wireless (MR 42) and switching (MS 250).
As explained in the Neat documentation [A], the Neat Pad and Bar cannot continue through the setup screen when using Meraki devices with default options for DHCP.
In our environment, we have a wireless SSID that is set to bridge clients to a Wireless VLAN subnet. This SID is using a Pre-Shared Key (PSK), it's not hidden, and is using both 2.4ghz and 5ghz bands with band steering. The DHCP server is running on the Switch Virtual Interface (SVI) configured on the Wireless VLAN subnet.
When trying to connect the Neat Pad and Bar to this SSID, the setup screen allows them to connect, but it say that it's not connected to the internet. The workaround for this is to configure the DHCP options in the SVI to include an NTP time server IP.
The steps are as follows:
Open the Meraki dashboard in a browser.
Navigate to Switch > Routing & DHCP:
Click on the row to open up the Switch Interface config:
In the section “DHCP options”, click the “Add a DHCP option” button. Select “NTP Server (42)”. Copy/paste in one of the direct IPs from the NIST Internet Time Servers page: https://tf.nist.gov/tf-cgi/servers.cgi
After that, you might need to reboot the Neat devices, but the Neat Pad screen should say that the wireless connection has internet access and allow you to continue the setup.
I tried setting up a new Windows 10 VM in Hyper V with default options, but I sometime receive the following error when going thru the installation:
Windows cannot find the Microsoft Software License Terms. Make sure the installation sources are valid and restart the installation.
I thought it was an issue with my Windows 10 ISO, but the MD5 checked out OK.
The fix:
Power off the VM.
Edit the Settings on the VM.
In the Settings window, navigate to the Memory tab. Change the Minimum Ram setting in the Dynamic Memory option from 512 MB to something like 1024 MB.
Restart the VM.
