Turning off EWS Throttling in Office 365

Microsoft must have realized this was an issue – they finally made it easier to temporarily change EWS Throttling under admin control.

And by "easier" I mean it is "possible if you know exactly what you are looking for."

So to remove EWS Throttling

Login to Exchange Admin 

Click Support and follow with New service requests.

In the search field, search for Increase EWS Throttling Policy

Select that from the list

Click Run Tests – it will first tell you are throttled (big surprise)

Click Changing EWS Settings – select 30/60/90 days

Run Tests again.  – Should now be good to go.
