Disable all calendar notifications

I've got a real weird one here.

 

Customer wants to disable all calendar notifications / alerts for the whole company. They dont want to receive any kind of calendar notification on outlook desktop client, iphone, android, etc.

 

Customer is exchange 2016 on prem only.

 

There a way to do this?

  • Do you mean reminders for upcoming events? Afaik there is no way to turn those off globally, as the reminder is configured for each event/meeting request individually. You can disable the "Default reminders" option in Outlook on the desktop, which I suppose you can also control via GPOs. For OWA, you can toggle the RemindersEnabled, ReminderSoundEnabled and DefaultReminderTime settings via Set-MailboxCalendarConfiguration. For mobiles, you'll likely have to rely on the OS notification controls, Outlook mobile does allow for some granularity.

      Think I might have found a way to do this after all based on this article:

      https://darawtechie.com/2017/07/16/no-reminders/

       

      Ran the command through a powershell script that targets all mailboxes:

       

      ForEach ($Mailbox in (Get-Mailbox -RecipientTypeDetails UserMailbox))

       

      { Set-MailboxCalendarConfiguration -Identity $Mailbox -RemindersEnabled:$false -DefaultReminderTime 00:00:00 }
