Creating Office 365 Migration Diagram with PowerShell

A few weeks ago, I posted a concept migration diagram for Office 365 to Twitter and Facebook. Today I thought I would show you how you can do it yourself using PowerShell and PSWriteHTML PowerShell module. When I started working on this, I've thought I want to create before and after infrastructure to see how it will look when migration ends. I've initially planned to assign myself an Office 365 Visio Plan 2 license and do something manually, thinking it may be just much easier. Unfortunately for me, there were no free Visio licenses in my tenant, and my laziness took over, so I've decided to give it a go using PowerShell only.

Remove-Item : Access to the cloud file is denied while deleting files from OneDrive

I like OneDrive. It allows me to keep my data secure and always synchronized. If things go wrong, I can always get it back. I use it for almost everything. Even for my PowerShell projects, which are committed to GitHub, so in theory, I shouldn't need that. But every once in a while, I make some stupid mistake and delete a file that has yet not been committed to GitHub, and that's where the OneDrive comes in handy. Quick restore, and we're back. Unfortunately, sometimes things aren't as I would expect them to work. For example, let's have a look at this nice list of markdown files that are documentation for my module called GPOZaurr.

Mailozaurr – New mail toolkit (SMTP, IMAP, POP3) with support for oAuth 2.0 and GraphApi for PowerShell

Today, I'm introducing a new PowerShell module called Mailozaurr. It's a module that aims to deliver functionality around Email for multiple use cases. I've started it since native SMTP cmdlet Send-MailMessage is obsolete,  and I thought it would be good to write a replacement that adds more features over it as things around us are changing rapidly.

Office 365 – Limiting license to minimum apps required

Office 365 has a lot of options and applications to choose from. Enabling one E1, E3, or any other license gives the user a lot of features, including Exchange, SharePoint, and Teams. But what if you want to make sure that the user can access only Microsoft Teams? By default, you can do it manually during the assignment of the license. Simply choose only Apps you want to assign to a user.

Sending Messages to Microsoft Teams from PowerShell just got easier and better

Christmas time is upon us, and I've decided that my PSTeams module needs some love. I wrote it in late 2018 and updated it a few times at the beginning of 2019. This release hopefully is worth of having 1.0 version number. I don't do that often and usually go for build numbers changes only, but Microsoft Teams message cards have their limits on functionality. Therefore, there are not many things that can be added unless Microsoft opens up and gives us all the cool features of Adaptive Cards. PSTeams module uses Webconnector to send messages to Teams. That method only supports Message Cards, which even Microsoft calls Legacy. But legacy doesn't mean fully functional with some cool features of their own. If you're new to PSTeams you may want to read those 2 posts below to get information how to set it up.

Invoke-RestMethod : The underlying connection was closed: An unexpected error occurred on a send while connecting Graph API

In the last few days, I've got two reports that my PowerShell module for Office 365 Health suddenly started giving errors. This was a bit weird because it worked perfectly fine on my end. But while I could understand one person having an issue of their own, with their network or firewalls, if the second person comes along with the same report, that means something else is going on.

PowerShell way to get all information about Office 365 Service Health

Office 365 is an excellent cloud service. But like any service, there's some infrastructure behind it that has to be cared for. Since this is Cloud, Microsoft does this for you. But any problems Microsoft has to have some impact on your end users. And you may want to have that visibility for your users. Microsoft provides this to Admins when they login to the portal, but while useful you may want to use that data in other ways than those planned by Microsoft.
