Hide the attendees in appointments like bcc does and performance implications if sent to million users RRS feed

  • Question

  • Hi,

    I have a requirement of creating appointment with response requested flag for multiple users. User count may be sometimes in millions.

    My question is:

    1. What is the limit of recipients count? Is there any performance implications?
    2. The recipients should not be provided with other recipients details like BCC functionality. Is there a way to do so?

    I have an alternative way to achieve same: Sending individual appointments. And each appointment will have extended metadata to identify the appointments are for one particular purpose. What is the impact of going ahead with this approach in terms of performance?

  • You will find that you will hit many different limits and throttling polices.  Exch will "protect" itself from scenarios like this unless changes have been made.

    To send millions, says to me that Exch is not the best way to do this, you should use an alternative, maybe something like SP where users can vote/respond.

  • Thanks Sukh,

    For my scenario, I need to use any mail server and I am not supposed to use SP as meeting invite to be sent to the users. I thought Exchange server is best option for my scenario.
