Exchange 2013 powershell errors out, and Exchange 2013 ECP doesn’t work correctly

Today I wanted to introduce a little product that I’ve created in the last few weeks called Dashimo. It doesn’t cover everything I wanted from it (feature wise), but it already can be used in production. Therefore, I thought it would be a good idea to get some feedback on whether I should spend some more time on it or throw it in the dumpster. Dashimo joins it’s older brother Statusimo of PowerShell modules allowing an easy way to build HTML output. If it will feel familiar, it’s because it was inspired with Bradley Wyatt PowerShell script he did. It gave me the idea of how I would like to build something similar but in a bit different way then he did, with much more flexibility. Still, if it wasn’t for him, the idea wouldn’t be there, therefore you should send him your thanks.

If you feel this title is very familiar to you it’s because I actually have stolen the title from Kevin Marquette. I’m in awe of his posts that take you thru topic from beginning till the end. No splitting, no hiding anything, everything on a plate, in a single post. That’s why I’ve decided to write a post that will take you on a trip on how to work with Event Logs, something that is an internal part of Windows Administration. If you’ve never worked with Events and you’re in IT you most likely should make an effort to find out what it is and how you can eat it.

I’ve been using Ubiquiti Unifi for some years now, for both home and work usage. It’s great hardware at a great price, and the best thing for a software maniac like me is that it’s continuously updated. Some time ago I upgraded Ubuntu to 18.04, and things went a bit sideways. You see Unifi started to add to their DEB packages that Mongo 3.6 is not supported and therefore blocking any installation. The idea is, it works perfectly fine on MongoDB 3.6 but migration between 3.4 to 3.6 is just not straightforward. Long story short when I upgraded Ubuntu I was suddenly greeted with not working Unifi.  I’ve fixed that, and blogged about it how you can do so using manual steps – Ubuntu 18.04 – Fixing Unifi .deb package to run with 3.6 MongoDB. The thing is with each new version out I have to do multiple steps to fix every single package from Unifi (you see where I’m going right?). While a few years ago I would be stuck to use bash or some other workaround which would be a pain for me, this is 2019, and PowerShell Core works excellent on Linux systems! I know that installing PowerShell Core for hardcore Linux fans may not be as fun as it is for me, but you do get a lot of benefits from it.

I’ve been working with Windows Events for a while now. One of the things I did to help me diagnose problems and reporting on Windows Events was to write PSEventViewer to help to parse the logs and write PSWinReporting to help monitor (with use of PSEventViewer) Domain Controllers for events that happen across the domain. It’s handy and I, get those excellent daily reports of what happened while I was gone.

Security Identifier (SID) History is a useful mechanism in Active Directory (AD) migrations. It allows users and groups in a new domain to retain access to resources that still rely on permissions from the old domain. However, once migrations are completed, these historical SIDs can become clutter, posing both security and administrative challenges. While it’s best to remove unnecessary SID History as soon as you’re done migrating, many environments skip this step. Over time, decommissioned or broken trusts make cleanup more difficult, and domain objects can accrue so many old entries that you lose track of what is still required.

I shouldn’t be telling you that, but Active Directory Backup is an essential part of your Active Directory setup. When a backup of Active Directory happens, AD is aware of it. Following PowerShell solution allows you to get Active Directory Last Backup Time for the whole forest or by domain.

Today’s blog post is about Active Directory-integrated DNS and how to find duplicate entries. By duplicate, I mean those where one DNS name matches multiple IP addresses. While some duplicate DNS entries are expected, in other cases, it may lead to problems. For example, having a static IP assigned to a hostname that later on is also updated with dynamic entries.

Sending emails in Microsoft Exchange world using an alias for an account has always been a pain. It required working with workarounds such as setting up Shared Mailbox or Distribution Groups and using SendAs permissions. For years admins around the world were asking Microsoft to change this, and finally, in April 2021, they did! It’s a new feature of Office 365, and it requires action from Office 365 Administrator.

Two years ago, I wrote a blog post on how you can compare two or more objects visually in PowerShell that works on Windows, Linux, or macOS. I’ve been using that for a while, but it had a specific flaw. Comparing more advanced objects that you often see (for example, returned by Graph API, two config files) wasn’t working correctly, often throwing errors. The reason for this was that having nested hashtables arrays require more advanced logic. Today I’ve updated my module to use the ConvertTo-FlatObject function, which allows the Compare-MultipleObjects function to compare suitably more advanced objects hopefully. Of course, it should not throw errors anymore.

I must admit that it was a bit embarrassing to see my Administrator password expired when I tried to log in as Domain Admin to Domain Controller. I got this little message saying This user account’s password has expired. The password must change to logon. Please update the password or contact your system administrator or technical support.
