Used this script at a customer environment to remove AD ExtensionAttributes, also you can use Add, Replace or Clear
get-aduser -properties extensionattribute1 -searchbase “OU=USERS,DC=local,DC=lan” -filter * | Where {$_.extensionattribute1 -eq “ANYTEXT” } | % { Set-Aduser -identity $_ -Remove @{extensionattribute1=@(“ANYTEXT”)}}
For this post I was thinking to share my latest free training courses I found.

Create a file for example : Diskspace.ps1
Create a textfile C:\temp\servers.txt , and put the servernames under each other.
$DiskSizeReport = @()
$computers = gc C:\temp\servers.txt
$computers | ForEach {
$Disks = Get-WmiObject win32_logicaldisk -ComputerName $_ -Filter “Drivetype=3” -ErrorAction SilentlyContinue |
Select-Object @{Label = “Server Name”;Expression = {$_.SystemName}},
@{Label = “Drive Letter”;Expression = {$_.DeviceID}},@{Label = “Total Capacity (GB)”;Expression = {“{0:N1}” -f( $_.Size / 1GB)}},
@{Label = “Used Space (GB)”;Expression = {(Round($_.Size /1GB,2)) – (Round($_.FreeSpace /1GB,2))}},
@{Label = “Free Space (GB)”;Expression = {“{0:N1}” -f( $_.Freespace / 1GB ) }},@{Label = “Free Space (%)”; Expression = {“{0:P0}” -f ($_.freespace/$_.size) }}
$DiskSizeReport += $Disks

Just found a cool post on hybrid-365.com where u can read how to setup an Exchange environment for testing purposes in Azure
https://www.hybrid-365.com/exchange/exchange-basics/exchange-test-environment/
You can use this also for Exchange 2019 and for better understanding of the new topology it is good to read these info first.
https://docs.microsoft.com/en-us/Exchange/new-features/new-features?view=exchserver-2019
I’m testing this in Azure….
I also found another testing lab what’s kinda interesting to test, maybe i’ll post this later

Last week I began to dive a little bit into Docker but not on Windows box/bash but to run it ontop of Ubuntu. Offcourse Google and the right search terms helped me to set it up quite easily.
I installed different versions of Ubuntu, I used Ubuntu Server 18.04.4 LTS and Ubuntu Server 19.10. You can upgrade from 18 to 19 or install new version 19. About the differences there is a lot to read but then again, you dont need to upgrade, “if it aint broke don’t fix it”.
#NOTE:if your not logged-in as root, use this command
sudo apt-get update && sudo apt-get upgrade
#if root then
apt-get update
apt-get upgrade
apt-get update
apt-get remove docker docker-engine docker.io
apt install docker.io
systemctl start docker
systemctl enable docker
docker pull splunk/splunk:latest
docker run -d -p 8000:8000 -e ‘SPLUNK_START_ARGS=–accept-license’ -e ‘SPLUNK_PASSWORD=changeme’ splunk/splunk
After you run the command at point 4. above, then you get the Container ID shown at the red arrow below. You run the command “docker logs followed with the ID.
docker logs -f dd915b35edf327a75786b5166c2d367923ce247a83726ca77c6ed542f972ab64
I stumbled upon this command because I couldnt figure out why this container stopped when I entered a different password at step 4. And I had to troubleshoot this issue.
#Note: Use your own ip addres, and to check your ip, for example use this command and check your output. # ip a | grep inet
Finally found and made some adjustments to a Powershell script that checks the number of unread emails from mailboxes in Office 365 / Exchange Online.
And for this to run correctly and scheduled on a Windows box you have to first start these 2 lines with a service account so that you dont fill in the password in the scriptfile.
$UserCredential = Get-Credential
$UserCredential.Password | ConvertFrom-SecureString | Set-Content C:\Temp\scriptsencrypted_password1.txt
If you need more info let me know.

Requirements:

Microsoft Exchange Web Services Managed API 2.2
Perseverance (If this script doesnt work the way you want 😉
