I missed my contacts and notes in MS Outlook 2013. I don't know why it's happened. I only opened my Outlook and didn't see my data.

Hi,

Please try scanpst.exe to repair your data file:

You may also create a new profile to setup the account, check if the data is still available:

2) identifying and recovering data from this pst file

3) saving the recovered data to one or several new .pst files

Hi Friend, i think your Outlook files data got corrupted. To resolve this issue, we recommended you to firstly run scanpst.exe utility. This utility easily remove errors from your Outlook data & fix corruption issues within very short  interval. If Scanpst.exe not capable to resolve this query then you should try third-party utility like- "SysTools Outlook recovery software". This tool is more powerful to recover entire data of Outlook even it demo version shows preview of all recovered data and it export 25 items per folder. Software allows you to split heavy files of Outlook and resolve Outlook errors which present in your PST file.

It seems the PST file is corrupted or has some issues. If you haven't tried SCANPST.EXE, you must try it.

If this fails, you need to use a third-party PST Recovery tool to recover your contacts and notes from the PST file. Before buying any third-party recovery tool, you can use its free demo version. If you can see your contacts and notes in the recovered data, you need to buy the software. 

I can recommend you SysInfoTools PST File Repair tool here to recover your data from corrupted PST files. You must check its free demo version first.

Thanks.
