What is the Repair Calendar feature?
The Repair Calendar feature has been provided to help customers fix issues they encounter with repeating calendar entries such as meetings.
Specifically, this feature in Notes 8.5 fixes issues where duplicate repeating calendar entries exist in the mail file.
Please note that this functionality works only if the user is running an 8.5 Notes client AND the user's mail database is based on the mail85.ntf template from Notes 8.5.
For more information see the TN 1326680
