How do I delete all of my inbox messages at once? The inbox is full.
You can select multiple items in the InBox by clicking on one, holding down your shift key and selecting another message. When you do this every message between those two get selected. So click on the first, scroll down to your last message, hold down the shift key and click on last. Now you can click on Trash Can at the top of the page to delete them.
You mention that your mailbox is full. If you mean that you have a message about being at or over you quota, it might just be attachments that need to be deleted. To remove those click on Account, then Files at the top left of the page. Open the My Files folder and take a look to see if you have much in there. There will be another folder inside of it named Conversation Attachments. This is where files attached to messages from the InBox will be located.
