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...
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:

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 }
- That only affects OWA though, no other clients.
