- Issue: When a meeting organizer updates a meeting by adding participants, all external attendees may receive an update if there is a corrupted image contained within the message body.
- Workaround: If a meeting organizer intends to include images in the event invite, the images should be added using the attachment feature within the message body. It is not recommended that organizers utilize the Insert pictures inline feature.
Microsoft has made modifications to the Send Updates feature for editing meetings/events.
