This week Microsoft announced a bug with Exchange servers that can cause email queueing delays and potentially loss of email. Read more on the specifics here. While it took Microsoft only a few days to issue a workaround and a patch, the issue is the potential downtime and loss of communications that affects your business.
How does this affect you?
If you are running on-premise Microsoft Exchange servers, until you are patched, your servers will queue email. If you send more email than you have disk space on your servers, that email will be lost. Similarly, if you are using a 3rd-party inbox provider that runs on MS Exchange, email service will be disrupted until patched. Depending on disk space on these servers messages could be lost.
Does your business run on email?
If you are like most businesses, you run on email. You probably even take for granted that your email will be delivered within a reasonable amount of time. Issues like this show that email is not infallible and emphasize the need for an expert in email to maintain top email delivery.
