Your Outlook Data File Cannot Be Configured

I'm using Office 365 installed locally. Outlook opens and works just fine. But when I open Skype for Business after a minute or so, I get the error "Your Outlook Data File Cannot Be Configured.  [my file name](9).nst  The 9 is the ninth instance of this file since this error started occurring. Never had this problem over the past few years of using Office 365 with Skype for Business.

The error is coming from Skype for Business as this is the icon in the task bar that is posting the error message. Error doesn't happen if I never open Skype for Business.

Any idea on how to fix this problem?  I already ran the Microsoft Support and Recovery Assistant.


I can confirm that updating resolves the issue. Current version (as of writing) is Version 1705 (Build 8201.2075 Click-to-Run)
