Error 0×80070718 when opening pst or archive in Outlook

When trying to open an archive or any other PST file you can get the 0×80070718 error. This error refers to not enough disk space or quota to open the said file.
In case you are using disk quota, check the settings. In my case we were using offline files, and the quota there needed to be adjusted. To do so:

  1. Open control panel and click “sync center”
    sync1
  2. Now click “manage offline files”
    sync2
  3. A dialog will open and you can choose “disk usage”
    From there you can view the current use, which will be quite large if you’re seeing this issue.
    Then you can also choose to change the quota
    sync3 
  4. Now when you can use the drag button to change the quota to your liking, as well as the quota for temp files.
    sync4
