Google made the new Gmail available about a month ago as an option for users of the company's email service, but it looks like it will soon be the only option.
So far, regular Gmail users have had (and still have) the option to "try the new Gmail", while G Suite administrators have the option to try it on a limited or company-wide basis through Google's Early Adopter program.
But from July the new Google mail will be made available to all G Suite users who will gradually lose the option to opt out of the new plan. Presumably this change will also apply to Gmail users around the same time period.
G Suite administrators will have three options for rolling out the new Gmail to their company's users, according to Google's timeline for the new Gmail. They will be able to move users directly to the new Gmail but users will still have the option to opt out for a limited period of time.
They will also be able to allow users who want to try out the new Gmail. If G Suite administrators don't allow company users if they see the new Gmail, they'll see it anyway in four weeks when the new UI is universally allowed to be adopted. The latter option is the default setting.
So gradually all G Suite users will see the new look in two phases. About two months after July, those who don't have the new look will be automatically pushed to the new UI, but they'll be able to switch whenever they want over the next four weeks.
Three months after July, around October, anyone who made the switch to the new Gmail won't be able to go back.
Google email features, such as offline and confidential mode, will be disabled by default when the new version is released in July.
Google plans to release more changes to the details of the look in July, and encourages administrators to start distributing it directly to G Suite users.
