Re: Exchange IMAP outage?
I would argue that on-premises Exchange was a great piece of software up until Exchange 2013. I found it easy to install, configure, maintain, and use. My systems rarely had downtime and troubleshooting was relatively easy. However, since MS decided the cloud was where the money was on-premises Exchange has gone south. Exchange 2013 is written for Microsoft's use in their cloud and is not a good idea for a company to run themselves. MS wants all their users to move to their cloud and seem happy to make on-premises life miserable if need be. Then, when you get to the cloud this kind of crap happens.
