Turn on or off Offline Messages for admins

You can now send Skype for Business IMs to your contacts even if they aren't signed in. This feature lets your contacts know that you have been trying to reach them. You don't have to wait until someone is online before sending them a message. And you'll no longer receive those "Tony can't receive IMs right now. Status is unavailable or offline."

For Offline messages, it's important to know:

  • Offline messages won’t be archived in the user's mailbox.

  • Offline messages will be sent to the users mailbox and the user will be notified when they log in to Skype for Business and they come online.

  • If the message recipient's status is set to Do Not Disturb or Presenting they will receive a missed message that is sent from the recipient’s Skype for Business client.


You can learn more about it by looking at how to Use offline messaging in Skype for Business.
