Issue:
Email messages, calendar, tasks and other items are saved on a server or your computer, when they’re saved to your computer, they’re saved as Outlook Data Files (.pst or .ost).
Just like any file, there is a possibility that the Outlook Data Files can become corrupted. If you think your data files have been corrupted, we’ll show you how to repair or recreate the files.
FIX:
Rename and recreate a corrupted .OST file
Typically you can fix syncing errors by either renaming or recreating your Outlook Data Files.
Outlook 2010 and 2013
- Locate the .ost file.
- Click the File menu | then click Info.
- Click Account Settings | click Account Settings again.
iii. Click the Data Files tab.
- Click the data file that is set as the default.
- Click Open Folder….
- Rename the .ost file by right clicking on the file and selecting Rename.
– We suggest rename the file to ost.old.
- Press Enter on your keyboard.
- Open Outlook. Outlook should start to configure a new data file.
– This process can take anywhere from 10-60 minutes depending on your mailbox size.

When your mailbox has been rebuilt you’ll see the message, “All folder are up to date” in the lower right hand corner.
