I have Windows 8 and Office 2013 with Outlook. Since upgrading I seem to be having a few problems syncing my calendars (some dates will sync and others will not. I sync to a Google calendar so it keeps my phone updated)  as well as sometimes my mail will not appear (it says "no items to show") unless I close and open Outlook.

There used to be a "repair" command in Outlook, and searching for repair online it gives me several options of 3rd party add on programs. Microsoft says there is a "scanpst.exe file, but I can't find that in 2013. So how do I check and repair my pst file? It has been converted through a few Outlook updates and it is about 4 gig. I read that in older versions you should not go over 2 gig, but I have years of information so I can't see starting a new pst file and loosing everything. Suggestions??

Hi,

The Scanpst.exe of Office 2013 is located in one of these folders depending on your Office and Windows version:

32-bit Windows	C:\Program Files\Microsoft Office\Office15
64-bit Windows	C:\Program Files (x86)\Microsoft Office\Office15
64-bit Outlook	C:\Program Files\Microsoft Office\Office15
Click-to-Run	C:\Program Files\Microsoft Office 15\root\office15

If the .pst file is about 4 GB, I think it's still good to use:

The file size limits of .pst and .ost files are larger in Outlook 2010 and Outlook 2013

Hello,

First, you try Moderator's suggestion. If your problem still occurs, then you should move on any third party software. I would like to suggest you a PST Repair Tool to repair highly corrupted or damaged Outlook PST File and fix all the bugs on the behalf of my personal experience. You can also split your over sized Outlook Data File.

Thanks & Regards
