On the left side of the screen, find the Item Data block.
Find the meeting date. If your access privileges allow you to change the meeting, a Move to a Different Meeting link appears below the date.
Click the link to display a drop-down list of meetings in which you can place the item.
Choose the new meeting and click the Change Meeting button.
