In Airmail3 I have three Yammer folders in my Exchange / Office 365 account which cannot be deleted. I suspect they were put into my Exchange set up when, as a business, we used Yammer some 8 years ago!
They are only detectable in Airmail but the app’s developers have no constructive advice and simply point the finger at the [Exchange] server. Critically, the folders are not in Office 365 web app. Neither are they in the other email clients I use: Apple Mail, Outlook and Spark.
Any ideas how I can get rid of them?
Thanks
