Since a few days I experience regular (every 15 minutes) Appcrashes of Office application swith an activated OnePlace-AddIn.
Below you see entries form the Application Eventlog for Outlook and Excel.

I have already updated from OnePlace 8.6 to 8.6.1, but the problem persists.
Do you have any suggestions?
