Data File Check in Progress shown Outlook 2010

I am using Office365 and having Microsoft Outlook 2010 installed on a Windows 10 64 bit laptop. When open Microsoft Outlook 2010, the Data File Check in Progress gears show up in the bottom toolbar, and Microsoft Outlook becomes slow respond and sometime unresponsive.

I suspect the issue is that it have a 33 GB pst file and Outlook is having trouble reading the whole thing and fixing any errors. I'm trying to figure out how to cancel the data file check.

And here start.

After search online, found two suggestion,

deleting the outlook folder from C:\Users\Username\AppData\Local\Microsoft\Outlook or delete all the files within that directory

repair one or more of the PST files to get your Outlook running smoothly again

And I choose second option as a safe option.

First step, completely close and exit Microsoft Outlook, and then I locate where Outlook pst file stored

Second steps, locate the Microsoft Office Outlook 2010 Inbox Repair Tool- SCANPST.exe

c:\Program Files\Microsoft Office\Office14, or

c:\Program Files\Microsoft Office(x86)\Office14
