This was a frustrating issue to deal with in a large environment, effectively if you open any “Select an Organization Until” window such as when configuring rules for dynamics distribution groups you may see either a small number of OU records or no OU records at all, with the window simply stating “There are no items to show in this view”.
This most often occurs after Cumulative Updates are applied to a server but may be caused by a lack of configuration or a misconfiguration of the Exchange servers and will present as in the image below –

The PowerShell script below will connect to Datto RMM’s cloud platform, specifically the Merlot API, and close all non-critical alerts older than a specified date. This is all easily configurable and by simply changing the API endpoints should allow you to connect to any of Datto’s available regions.
For information on enabling or configuring the Datto API please refer to the official documentation – https://rmm.datto.com/help/en/Content/2SETUP/APIv2.htm

The PowerShell code below will take a CSV list of mailboxes and Users/Groups to remove from that mailbox. This allows you to quickly and efficiently remove old permissions across Exchange.

Yet another short one with little context or reason.
A colleague of mine needed a list of all Service Principal Names assigned to all servers on the estate. Searches online brought us to a few potential solutions, most of which included the use of some difficult to use and understand .NET classes which appeared to be limited to only 1000 results.
So that got me thinking, these are just Active Directory attributes so why not use PowerShells very own Get-ADComputer?
The script below will list every single server in Active Directory and all assigned SPN’s, it will then export the list to a CSV.

This will be a bit of a reference guide to updating a CosmosDB collections and nested items in a nice manner. This thread will not cover how to use the CosmosDB package in Node.JS and it will assume you’ve successfully connected to a database.
I will use the example of updating the signature of a user of a forum where that signature is stored in a collection which is the overall thread and then nested collections which are the individual comments.

Another short article with little context today.
The PowerShell script below will produce a report showing the Last Logon time of all enabled Active Directory users, it will also connect to Exchange On-Premise and request the last logon date of the mailbox. This can be useful to identify user accounts which are no longer in active use, even in organisations where mailboxes may have been retained once a user left.
There’s also a nifty status update built in that will tell you exactly how far the script has progressed and show an estimated time to completion.

Short one today, the script below will import a CSV from C:\temp\users.csv that contains a ‘User Name’ field and will locate all Active Directory users that match that. Where multiple matches are found it will populate the exported CSV with all matches.

I’ve recently been messing around with custom ROM’s, rooting and all that good stuff on Android and came across an issue when trying to re-apply the stock image on my OnePlus Five.
When trying to install the original stock ROM to the device I received the following error message –
E:String resource 'zip_compatible_err' not found.
Using default value.
Zip Treble compatibility error!
Invalid zip file format!
Error installing zip file 'source'
Although it took me ages to figure this out, the fix is actually very simple –

Occasionally you may have to implement something which will improve the security of your organisation but that does introduce a risk. Often the correct way to determine if it will cause issues is to enable logging and then to review those logs.
But what if you don’t have centralised logging?
This article does not replace a fully functional centralised event logging system which I would strongly suggest anybody have, however, it will allow you to retrieve specific logs from all servers in your estate. If your estate is too large then the script can be modified to instead of storing all of the data in the $allEvents variable you could simply append it to an Excel file inside of the for each loop.

This is a frustrating issue to come across when trying to roll out AD Schema Updates during an Exchange Cumulative Upgrade. But luckily it’s normally quite simple to resolve, this article will cover the various solutions from most to least likely to fix the issue.
