Not yet @justin.christie; however, I have good reasons to believe there might be an issue on your end. We haven’t received any other report in the Forum and our Support Team has confirmed, they haven’t heard about this issue either. Since your whole company is affected, I suspect someone might have changed a setting in your Outlook account which could have triggered the issue.
Could you please check with your IT department if any update/modifications were made over the last few days? I haven’t heard of our Team yet, but I’m hoping to hear from them soon, I’ll keep you posted as soon as I do!
