Blocking spam emails with hidden or missing From address

Recently, I’m getting more an more spam in my Inbox with no email address.
The From field only shows a name but no email address. Also, when I hover over the name or right click on it, it doesn’t open a Contact Card with more info.
Right clicking on the message in the message list doesn’t allow me to block it either.
How can I block this new type of spam?
Folder sorting order in Shared Mailbox changes back randomly

We’ve got several subfolders for the Inbox in a Shared Mailbox which we want to sort in such a way that the most frequently folders are at the top. The rest can remain ordered alphabetically.
We have no issues changing the sorting order at first. However, the sorting order seems to randomly get reset again and the folders end up in their original location.
We’ve tried renaming the folders with special prefixes as well, but that ended up in an even bigger mess.
Is there really no way to manually sort the folders of a Shared Mailbox and make them stay in their location?
How to install and run the New Outlook and Classic Outlook side by side
Navigation Pane is on the left instead of bottom of the Folder List

After an update of Office, Outlook now displays the navigation buttons for Mail, Calendar, Contacts, Tasks, etc… on the left side next to the Folder List.
These Navigation buttons used to be displayed within the Folder List at the bottom.
Where is the option to move the Navigation buttons back to their original location?
Where did it go? Disable Hardware Graphics Acceleration

I’m getting some weird graphics anomalies with my screen when using Outlook.
For instance, the screen suddenly turns completely black or white, and when I move over those spaces with my mouse, the Outlook UI starts to appear again but only in those places.
At other times, text in the Ribbon and Folder Pane overlap or folders appear empty even when they are not.
Restarting Outlook fixes it temporarily but I’d like to fix it permanently.
I was recommended to “disable hardware graphics acceleration” but I can’t find that option anywhere.
How do I solve this issue?
