If you’re like me, you're probably running Windows 10. The majority of your AppData files are stored on this C: drive which can take up quite a bit of space especially if you have a SSD drive with limited space.
When I was trying to sync my Gmail account (which I’ve had since 2004) with Outlook 2016 I soon realized all these email messages were going to take quite a bit of storage space. I tried moving the OST file Outlook 2016 created when I added my Gmail account, however Outlook simply re-created the file in it’s default location. No registry or other “fixes” I found on the web seemed to make it possible to move.
So, after trying different ways I decided to use a nice little command that Windows 10 has called MKLINK. Using MKLINK you can create a symbolic link from any file at any location to another file or location. Pretty much a “shortcut” to the file.
To do this, I did the following:
- Open a CMD (Command Prompt) as an administrator. (Run as Admin)
- Locate your Outlook OST/PST AppData files.
- Typically, this is: C:\Users\<your username>\AppData\Local\Microsoft\Outlook
- Mine was called “<my email address>@gmail.com - Jean Gionet.ost”
- Now I have a 1TB drive in my machine which is assigned to the D: drive. This is where I want to move and store my Outlook OST/PST files.
- Using File Explorer, I created these folders: d:\users\<my username>\Outlook Files\
- Now MOVE/cut your “<my email address>@gmail.com - Jean Gionet.ost” from your C: drive and paste it in “d:\users\<my username>\Outlook Files\”.
- Now back to your Command Prompt type for following replacing the <> and D: values with your own.
- mklink /d "“<my email address> - Jean Gionet.ost" "D:\Users\<my username>\Outlook\<my email address>@gmail.com - Jean Gionet.ost"
- Press ENTER
- You should get this message:
- symbolic link created for\<my username>@gmail.com - Jean Gionet.ost <<===>> D:\Users\<my username>\Outlook\<my username>@gmail.com - Jean Gionet.ost
- You can verify that your old file is now a symlink by looking at it in File Explorer.
- Your Done!
- You can NOW open Outlook 2016.
Hope this helps someone who’s been trying to find a workaround for moving OST/PST files!
