How to solve the problem of sending e-mails (exchange 2013) to people whose accounts are turned off (in AD)?
At the moment, no information comes that the message will not be read. I cannot delete these inbox because I cannot lose my data.
Please help me solve the problem.

    If you want to apply to all senders, you have some options:

    Using the same link, only allow a specific sender to sent to it (you?)


    or set the send/receive quota ( and the other mailbox quotas ) to 0

    You want those messages to bounce back to the external sender?

    You could require authentication for senders and it will

    set-mailbox <user> -RequireSenderAuthenticationEnabled $true

    Hi @matitdob ,

    How to solve the problem of sending e-mails (exchange 2013) to people whose accounts are turned off (in AD)?

    By "accounts are turned off (in AD)", do you mean you have disabled their AD accounts while the mailboxes are still active?


    If this is the case, by default disabled user accounts can still receive mails(See this article.) so in other words, the incoming message can still arrive these mailboxes.

    From your description, do you mean it's ok that they can still get messages, but meanwhile you would like the senders to get a notification that their messages won't be "read" by the original mailbox owner? If my understanding is correct, I'd suggest configuring Automatic Replies settings for these mailboxes as a workaround.

    For instance, in my test environment, user10's AD account has been disabled, then I run the command below to configure the auto reply for the mailbox:

    Set-MailboxAutoReplyConfiguration -Identity user10 -AutoReplyState Enabled -InternalMessage "You message won't be read by user10." -ExternalMessage "You message won't be read by user10."  

    Now when a user sends a message to user10, the following auto reply message will be triggered:

    Feel free to let me know if I have misunderstood anything.
