How to fix outlook issue on corrupted ".ost" file

Windows 8 introduced another interface to read emails, which for is kind of useless because it is too slow.
anyway, if you have a Microsoft account on the cloud and try to hook your Outlook, chances are you'll get an OST issue when you start your Outlook.

This is how I fix it:
1. Delete the original .ost created by Outlook (usually at C:\Users\User\AppData
Local\Microsoft\Outlook\yourmail.ost.

2. Go to Control Panel -> Mail -> Remove the account.

3. Create a new data point inside a user space (somewhere in C:\). Set as default

4. add back the account. You'll see the original location in Step 1 OST populated with the data.

5. Point back the data point from Step 3 to the original data point in Step 1.

Restart the outlook and it will read off from the original data point.
