Due to some changes in tax laws, our partner is taking time to deliver renewal keys of our Office 365 subscriptions (Office 365 Enterprise E3 plan). We don't expect the keys to be delivered before the expiry date (Sunday) passes.
According to this article, the subscription is placed in a "Expired" state and users generally continue to have full access to documents.
Our main concern is whether email will be delivered to our Inboxes from external senders during this "grace" period? Does anyone have real experience with this scenario? Can we risk keeping the subscription in expired state for 3 days or should I go ahead and purchase subscription at retail price?
