Moving Outlook 2013 IMAP Data Folder to Other Place

If you want to move your Outlook 2013 IMAP Data Folder to Other Places instead of
C:\Users\username\AppData\Local\Microsoft\Outlook
then you can follow trick below:

1. Rename
C:\Users\username\AppData\Local\Microsoft\Outlook
to
C:\Users\username\AppData\Local\Microsoft\Outlook-old
2. Create New Folder where you want the IMAP Data Folder to be stored, Ex:
D:\Email
3. Open command prompt as Administrator and then type syntax below:
C:\WINDOWS\system32>mklink /D "C:\Users\username\AppData\Local\Microsoft\Outlook" "D:\Email"
symbolic link created for C:\Users\username\AppData\Local\Microsoft\Outlook <<===>> D:\Email
4. You can move all of IMAP Data Folder that in
C:\Users\username\AppData\Local\Microsoft\Outlook-old
to your new place (D:\Email) or you can retry to add your IMAP Account Again in Outlook.

Outlook is fooled into still thinking they’re in the old location. But the important part is the new OST’s will be in the desired location.
