And that may not be a good thing in all cases... Known issues to be aware of:
[1] Exchange ActiveSync is broken under certain configurations. Apple is aware of the issue and pursuing a fix. [2] The default picture format for iPhones 7/8/X is changing. As a Microsoft employee wrote earlier today: The new photo and video formats result in files about 1/2 size of the old JPEG and video formats, while having better quality. The problem is that new files will likely not open properly outside of your phone until everything that you use to work with photos updates to work with new HEIF formats. To check if your iOS 11 phone uses the new format, go to Settings > Camera > Formats. "High Efficiency" is new and "Most Compatible" is the old / current. I do not suggest to just turn this off; hey - getting files half the size is super cool. Just realize that if you use the photos outside of your phone that there might be temporary issues with viewing. Windows and OneDrive do not yet support the new formats. h/t ninob You may wish to suggest to your user communities that they delay upgrades because of the EAS issue.
