Using classic Outlook for Windows in business environments
Hi Benka Kolceg (DTP),
Unfortunately, calendar responses (meeting invitations, accept/decline responses, or updates) cannot be recalled in the same way as an email message.
If the calendar invite or response has already been delivered to the recipients' mailbox, Outlook does not provide a feature to retract or recall it. The recommended approach is to send an updated meeting invite, cancel the meeting, or contact the recipients to explain the mistake, depending on what needs to be corrected.
If having the ability to recall calendar responses would be valuable for your workflow, I encourage you to submit feedback through the Microsoft 365 Feedback Hub. This is the best way to ensure your suggestion reaches the product team and can be considered for future improvements.
After submitting your feedback, you're welcome to share the feedback link here. I'd be happy to upvote it to help increase its visibility.
Kind regards,
