We resolved an issue that prevented some users from saving their out-of-office settings.

If you attempt to send a message to a contact who has opted out, the message will not be displayed in the message box after failing to send.

Previously, if you added a file to a message using drag-and-drop but didn't type any text and then clicked outside the message box, the file preview would disappear. Now, the file preview will remain in the message box even if you click away, allowing you to return to your message and send it when ready.
