I have an Exchange work calendar syncing with my iPhone (iOS 11.3) and often I have many new work invitations appearing on my iPhone notifications and subsequently on my Apple Watch too. For all of these invitations, I manage the replies (Accept/Decline) on my work computer. The only reason I have my iPhone syncing with my work calendar is to see which events are coming up in the next 15 minutes, and to see which room they're at.
Is there any way to hide all work event invitations from my iPhone? I only want to see the events as part of my iOS calendar. I don't want any work events appearing in my notifications (except event reminders shortly before the event happens; those are fine). Lastly, I'd like to keep my personal event invitations, so turning off all calendar notifications doesn't seem to be a good solution.
