The situation is slowly improving, although email delivery times are still far from perfect. It looks like a lot of Exchange Online Protection servers are affected which significantly slows down email processing for scores of users in North America no matter if they use 3rd party email processing services or not. We are continuing to actively monitor the situation. We have powered up multiple additional cloud instances on Azure to make sure our service is scaled up to guarantee max performance at the moment and also when Microsoft fixes the problem and releases the messages that have piled up.

We are continuing to work on this. It seems to be a Microsoft performance issue. Messages processed by CodeTwo cannot be delivered back to Microsoft 365 in a timely manner. We're seeing signs of recovery though. More and more messages are being processed and the queues are getting smaller. All messages will be eventually delivered with signatures.
