We know that businesses today don’t operate in isolation; employees work not only with one another, but with third-party vendors, clients, customers, and other businesses as well—and often on a temporary basis. To keep your organization’s information safe in these situations, we’re introducing the ability to set an “expiration date” for specific user access to files in Google Drive, Docs, Sheets, and Slides.
For instance, imagine your business hires an outside contractor for a project lasting three months. To complete the job, that contractor needs to view a spreadsheet containing the contact information of your employees. Following this launch, you’ll be able to share your employee list in Sheets with the contractor, give them view access only, and set that access to expire when their contract does (in three months). If the contractor attempts to open the spreadsheet after the expiration date has passed, they’ll be denied access.
This functionality, coupled with the Information Rights Management (IRM) features we launched last July, should significantly increase the security of your organization’s documents and information.Please note that you’ll only be able to set expiration dates for users with comment or view access; you will not be able to set expiration dates for file owners or users with edit access.
IMPORTANT: This feature will roll out gradually over the course of two to three months; please note that you may not see the feature in your domains until mid- to late Q2 2016.
Launching to Rapid release, with Scheduled release coming in two weeks.
Gradual rollout (2–3 months for feature visibility)
