Outlook error.

Hello,

We have a lot of Office 365 users getting the attached message in their Outlook.  

Any idea of where we should check?

Thanks.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This doesn't appear to be anything you've done, but rather a problem Microsoft is trying to address on their end.

"Around 1:10 p.m. central time (on September 5, 2018), Microsoft tweeted that it was aware of the "throttled" issue and taking steps to address it."
