What type of messages are stored in the pending folder?

The pending folder specifically contains messages that are waiting for a response from someone else. This means that the messages stored in this folder are not yet resolved or completed because they rely on input or feedback from another individual before they can be finalized. Essentially, these are communications that you are awaiting further engagement on—whether it’s a reply, approval, or additional information—which is necessary for continuing the workflow or project at hand. By organizing these messages into a pending folder, it allows for efficient tracking and follow-up as needed.

The other options do not accurately reflect the nature of the pending folder. Messages that have been completed would typically be moved to a different folder for archival, while messages requiring action later might suggest tasks or to-do items rather than awaiting someone else's response. Lastly, messages that are no longer relevant would not be stored in the pending folder, as they no longer demand any attention or follow-up.
