I am using Office 2016 provided by Office 365. Since about 30 days ago when I try and search my Outlook inbox it attempts to for about 15-20 seconds and then prompts me with a message saying "We're having trouble fetching results from the server..." and it gives me an option to "Search in emailed stored on this computer" which when clicked shows me email stored in my local inbox. It's becoming a waste of time.
I originally ruled out a .OST corruption issue when I realized it was happening on my laptop and my desktop. However I still went through the steps to compact and repair my .OST, re-index my Outlook, delete and remake the profile. The issue is still there.
