• The Personio iCal subscription is corrupting my Outlook data file (.ost)

The Personio iCal subscription is corrupting my Outlook data file (.ost)

Issue:

When Outlook processes a new or updated event from a Personio iCal subscription, the local Outlook data file — an .ost file — becomes corrupted and Outlook crashes. This is a known local Outlook behaviour when processing certain iCal events. It isn't caused by a configuration in Microsoft 365 or a setting within the Personio integration.

Possible solution:

1. In Outlook's account settings, remove the affected Personio calendar subscription.
2. Allow Outlook to delete or recreate the corrupted data file. If prompted by an error message, confirm the action.
3. In Personio, regenerate a new iCal link and add it back to Outlook as a fresh calendar subscription.
