Agreed on the copy/paste etc, but just stop with the Exchange stuff.
Exchange is a joke, and this perception in certain circles that it is THE "enterprise" or "business" email system is an absurdly ignorant delusion. Its penetration in the largest sectors like Higher Ed, Finance, and research science (read: Biomed, folks), is nearly zero. And if you think Higher Ed doesn't count as "enterprise", then you're using a meaningless, retardo-analyst definition of the word.
It is a flip of a switch to enable IMAP use of an Exchange Server, and anyone who thinks it adds any security risk is a FUD-sucking moron who has demonstrated by their lack of brains that they should never be allowed to work in this industry again.
