If you encounter the problem with outlook getting stuck minimized in the task bar, and not wanting to maximize, there here is a quick fix:

Find Outlook in the start meny, and choose to “Open File Location”.

You should now be able to right click on the Outlook icon and choose “Properties”, this will show you this dialogue:

Under the Shortcut tab, from the “Run:” dropdown, choose “Maximized”.

Save (you’ll need to be admin for that) and then you’re good to go. You might have to reboot for it to start working.
