Every time when opening MS Outlook user gets the following warning:

Internet Calendar Subscriptions.pst cannot be found

Outlook Data File
The file C\Users\<username>\AppData\Local\Microsoft\Outlook\Internet Calendar Subscriptions.pst cannot be found.


The issue was resolved by going to Outlook > Account Settings > Account Settings > Data Files and removing the offending Internet calendar file.

Outlook > Account Settings > Data Files

If you had subscribed to any Internet Calendars (i.e. Google Calendar) you may need to re-add them.
