Calendar Repair Assistant
Behind the scenes, Office 365 runs a tool called Calendar Repair Assistant (CRA), which "detects and corrects inconsistencies" in meeting information. It makes sure that the meeting time, location, and attendee information on the calendar of the person who proposed the meeting matches the information on everyone else's calendar (and vice versa).
This article applies to: Microsoft Outlook
For more information about how calendars can get out of sync, see our Maintain Calendar Harmony article.
You may not notice CRA at all, or may see one of the following:
- A meeting you deleted from your calendar reappears.
- You see the message "Your meeting was found to be out of date and has been automatically updated."
- You see this text appended to the bottom of the meeting notes.
Outlook re-created a meeting that was missing from your calendar. The meeting was re-created because the meeting organizer previously received an Accepted or Tentative response from you. To make sure the calendar item is up to date and the organizer has your latest status, please accept or decline the meeting from within your calendar.
If, later, you decide you cannot attend a meeting you accepted, highlight the meeting on your calendar, then click Decline in the toolbar or ribbon. Don't just delete the meeting. See our Responding to Meeting Invitations article for your preferred email client (app) for more information.
Another cause of calendar discord can occur when you use a mobile device to accept or decline a meeting. We strongly recommend that, when it comes to your calendar, you only use your mobile device for viewing, not accepting or declining. Use Outlook or Outlook on the web to accept or decline meetings.
