Emails Delivered without EOP scanning
We recently switched our Office 365 email security provider from Mimecast to Defender plan 1. We have our Defender policy settings set as strict as possible, but we are still seeing a large increase...
Microsoft has basically told us this is by design and not something we can change. It seems like a very big security hole to delay scanning until after delivery when the workload is too high. I wish this is something we had known about prior to switching email security providers.
