The messages are currently delivered without delays. We will now monitor the services.

We are seeing signs of recovery. Next update in 30 minutes.

Microsoft has reported the following incidents in EAC:

EX394347 - https://admin.microsoft.com/Adminportal/Home#/servicehealth/:/alerts/EX394347
EX394348 - https://admin.microsoft.com/Adminportal/Home#/servicehealth/:/alerts/EX394348

We are monitoring the problem. We can see that lots of messages are delivered successfully after a second try. Next update in 30 minutes.

We are currently investigating this problem. Some messages cannot be sent from our service due to a degraded performance of a large number of Microsoft Exchange Online Protection servers. Our retry policies usually manage to successfully sent messages via different servers that are currently available, but it may take a few minutes for the messages to reach final recipients. Signatures are imprinted as normal. Next update will be provided in 30 minutes.
