Configuring preferences and options in Outlook.com
I'm getting no help from MS support here. I tried escalating it with the team that support my business account. But as they are a separate team it appears they have no escalation route. I'll try again with the in-app support - although I've been cut off each time the storage crashes the OS and each new agent takes us back to square one. Quoting the ticket number doesn't seem to help.
I guess we'll just have to stop using Outlook....
