Investigating

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.
