Unity VR (XR) camera not located at the position you add it in the scene

The camera is directly controlled by the engine and you may not be able to specify its position. What you have to do is to center the camera in the scene (0,0,0) and then put this inside a empty object. You can then position this camera containing object to where you want the player camera to be located

It may be a good practice to call below just to be sure camera is initialized and centered just before your scene starts
UnityEngine.XR.InputTracking.Recenter();

Removing outlook profile

Outlook giving error "Before deleting the e-mail account containing your personal mail, contacts, and calendar data, you must create a new location for your data", when trying to remove email account

I have tried this with Outlook 2016 in Windows 10

Close Outlook if its running
Start -> Run (or Win Key + R) -> outlook.exe /manageprofiles -> OK
Click "Show Profiles" button and delete it
Close window and start outlook
Outlook should ask to create a new profile now
Now you can enter your email address and configure outlook as normal

Setting a proxy for a standalone Microsoft .Net application

Find the applications install location (or .exe location). If you are using a shortcut, you can right click, and check the properties to find this place.
Locate your applications .config file. Typically this will be in the same folder as your .exe; For example, for myappname.exe, you should be able to see myappname.exe.config in the same directory
Create one if there there is only not already present. Make sure to name it myappname.exe.config
If creating a new file, Open the newly created file in notepad, and paste the below into it. Make sure to change proxyservername & proxyserverport in your environment
if file already exists, add the defaultProxy section as shown below and save file
Restart the application

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.net>
    <defaultProxy enabled="true" useDefaultCredentials="true">
      <proxy proxyaddress="http://proxyservername:proxyserverport/" bypassonlocal="false" usesystemdefault="false" autoDetect="false" />
    </defaultProxy>
