Outlook 2010 and 2013 'team' calendar shows AD accounts without mailboxes RRS feed

  • Question

  • When we create AD accounts for contractors, temps, etc that need to access the network, we assign the 'Manager' attribute in AD to employee responsible for the user. In many cases, this is a manager.

    We've discovered that, AD Accounts that have no Exchange mailbox, email address defined, really anything more than being a security context in our AD domain are showing up as part of the managers Team in the calendar view of Outlook 2010 and 2013.

    Is there a way to keep the team view, but not display the AD accounts that are not exchange enabled, mail enabled, have a mailbox or really any Outlook/Exchange/Email configuration whatsoever?

    I've included screenshots of the team calendar view in Outlook, along w/ all the AD attributes sent for the account 'b lund'.  Is there anyway to prevent 'b lund' from not appearing under the manager in Outlook, since there is no email nor exchange attribute for the account?


    OK, so I guess I have to wait for my account to be verified before I can post images, but the attributes with values in AD are not exchange relevant, I promise :)

  • Hi,

    Based on my knowledge, the Team Calendar in Outlook is based on the Manager field in the Organization tab of User properties. It is an AD level attribute instead of mailbox level. If you want to disable a user visible in the Team Calendar, we can directly remove the Manager field for this user in AD.

    If you don't want to remove the Manager field, we can use the Exchange distribution group for Calendar view instead of Team Calendar as a workaround. We can create a distribution group in Exchange server with two conditions: Manager field = Boss1, Mailbox enabled. Then open the distribution group calendar in Outlook to view schedules.

    Here is a similar thread for your reference:

  • We use manager to identify owners of service accounts etc.  We move users to a different OU in the AD when they no longer work for us.  But Exchange picks up ALL accounts that have matching manager and displays them as team members in the calendar.  Can we restrict it to a particular hierarchy of OU in the AD?  We should not need to change the use of manager in the AD just to fix an issue with Team Calendar in Outlook.  There should be a way of restricting the accounts used.  It should exclude disabled accounts in the AD at least and I can't imagine any users having a problem if it also excludes accounts that don't have the mail attribute.

  • You should be able to hide these from the GAL - even though they don't have a mailbox they'll likely still be "known" to Exchange. You can check here:

    Get-MailUser johns | select HiddenFromAddressListsEnabled

    You can then set the user to be hidden here:

    Set-MailUser johns -HiddenFromAddressListsEnabled $true
