Exchange 2010 - Delete calendar entries - all mailboxes - Retention policy

    Question

  • Hi,

    We are using Exchange 2010 version 14.3 (Build 123.4). 

    We have many users that have a lot of calendar entries which also have attachments to them and in turn cause mailboxes to fill up quickly. So, my question is, is there a way to use the retention policy feature to permanently delete calendar entries from all mailboxes?

    If not, can you recommend a better way? (Management shell?)

    Any help is appreciated.

    Cheers

  • Hi  barvcontrol,

    We can use the command below to create a retention tag for calendar folder in Exchange 2010 SP3:
    New-RetentionPolicyTag "For calendar" -Type Calendar -RetentionEnabled $true -AgeLimitForRetention 30 -RetentionAction PermanentlyDelete
    Then we add this tag to retention policy, and run Start-ManagedFolderAssistant -Identity morris.cornejo@contoso.com for this mailbox, wait for some times (may be 1 day), it will be applied to this mailbox.

    We can also take steps below to delete those meetings:
    1. Open outlook and click Calendar.
    2. Click View in the menu bar.
    3. Choose List in Change View button.
    4. Click the Start which showed in the picture below, then meeting will be listed in the order of time.
    5. Click the oldest meeting, then hold Shift to click the meeting which you want to delete, meetings between those two meetings will be choose, then click Delete.

  • Hi Kyle,

    Thanks for your reply. We don't want to do it from the client. We want to apply it globally to all staff so I will try the retention policy method and let you know how I get on.

    Cheers

  • Just tested it on my calendar and it deleted everything out of my retention period which means that is has worked.

    This linked helped as well. https://docs.microsoft.com/en-us/powershell/module/exchange/policy-and-compliance-retention/new-retentionpolicytag?view=exchange-ps

    Thanks for your help.
