Meetings are not processed or messages are automatically deleted with a non-default AutomateProcessing parameter value

Symptoms
When you receive a meeting request in an Exchange Server 2007 or later version mailbox, the meeting does not appear automatically on your calendar in a tentative state.
Cause
This problem occurs under either of the following situations.


  • The processing of meeting requests has been disabled for your mailbox in the Exchange Calendar Assistant

    In this situation, if you use the following cmdlet in the Exchange Management Shell, you will see the value of the AutomateProcessing parameter is set to None.

    • Exchange Server 201 0and later versions:

      Get-CalendarProcessing <alias> |FL AutomateProcessing
    • Exchange 2007:

      Get-MailboxCalendarSettings <alias> |FL AutomateProcessing
NOTE: In some scenarios for user mailboxes, the AutomateProcessing parameter has been seen to have a value of AutoAccept, even though the AutoAccept value can only be applied to Resource mailboxes. In this configuration, there have been reports of automatic deletion of e-mail messages sent to the mailbox. If the output from the above cmdlet shows the AutomateProcessing parameter value is set to AutoAccept on a user mailbox, use the solution in the Resolution section of this article to reset the AutomateProcessing parameter back to the default value (AutoUpdate).


  • The AddNewRequestsTentatively parameter is set to $False

    In this situation, if you use the following cmdlet in the Exchange Management Shell, you will see the value of the AddNewRequestsTentatively parameter.

    • Exchange Server 2010 and later versions:

      Get-CalendarProcessing <alias> |FL AddNewRequestsTentatively
    • Exchange 2007:

      Get-MailboxCalendarSettings <alias> |FL AddNewRequestsTentatively
Resolution
To resolve this problem, use the appropriate cmdlet listed below, depending on the results of the cmdlets provided in the Cause section.


  • Change the value of the AutomateProcessing parameter to AutoUpdate.

    • Exchange Server 2010 and later versions:

      Set-CalendarProcessing -identity <alias> -AutomateProcessing AutoUpdate
    • Exchange 2007:

      Set-MailboxCalendarSettings -identity alias> -AutomateProcessing AutoUpdate

    Note
    In the above example cmdlets, replace alias> with the appropriate identity value for the mailbox.

  • Change the value of the AddNewRequestsTentatively parameter to $True.

    • Exchange Server 2010 and later versions:

      Set-CalendarProcessing -identity <alias> -AddNewRequestsTentatively $True
    • Exchange 2007

      Set-MailboxCalendarSettings -identity alias> -AddNewRequestsTentatively $True

    Note
    In the above example cmdlets, replace <alias> with the appropriate identity value for the mailbox.

More information
By default, in an Exchange Server 2007 or later version environment, meeting requests are automatically marked as tentative by the Exchange Calendar Assistant. However, if you disable the sniffer process in Outlook 2007 or later versions, the AutomateProcessing parameter for the user's mailbox is changed from AutoUpdate to None.

The following setting in Outlook controls the sniffer feature in Outlook.

  • Outlook 2010 and later versions:

    Automatically process meeting requests and responses to meeting requests and polls



    To get to the Automatically process meeting requests and responses to meeting requests and polls setting, use the following steps:
    1. On the File tab, click Options.
    2. On the Mail section, scroll down to Tracking.

  • Outlook 2007:

    Process requests and responses on arrival



    To get to the Process requests and responses on arrival setting, use the following steps:
    1. On the Tools menu, click Options.
    2. On the Preferences tab, click E-mail Options.
    3. Click Tracking Options.
