It's poor practice in my opinion when you release a build you can't support until Monday. SM 16 .6670 is a disaster and causing major issues for us. Yeah, I should wait a few days to install to resolve the Friday build problem but as a software company don't release something right before you are not available for two days.

 

Now waiting for someone to fix the major issues in 6670 that started with the last build. Nothing is being deleted on the server that's deleted in Outlook (Windows and Mac AND Apple Mail), web mail is crawling, etc. etc.
