Important Notice for Zoom Users


9-month release window

Beginning November 1, 2021, customers will be required to update their Zoom software to ensure it is no more than nine months behind the current version at any given time. From that point on, users will be prompted to update their software if their version falls behind this nine-month window. For example, if the latest version of the Zoom client was released in September 2021, customers who try to access Zoom services with a version released before January 2021 will be prompted to update to a more recent version in order to access the full functionality of Zoom.

This change is in line with industry practices and designed to help ensure that Zoom users receive the latest Zoom features, as well as any privacy and security enhancements we make to the platform. To prepare for the new schedule, we recommend customers update to the latest release supported by their organization or at minimum software version 5.5.0, prior to November 1st, 2021.

As always, we recommend you regularly download and update to the latest version of the Zoom software by checking for updates within the Zoom client or by navigating to to take advantage of all our latest security and functionality features.

This policy will affect the following products (oldest possible version as on November 2021):

  • Zoom Client: Windows, macOS, Linux, iOS, and Android (5.5.0)
  • Zoom Rooms (5.5.0)
  • Zoom Rooms Controller (5.5.0)
  • Zoom Phone Appliances (5.6.0)
  • Outlook Plug-in (5.5.1)
  • Browser Scheduler Extensions for Chrome (1.6.3) and Firefox (2.1.13)
  • VDI Client (5.5.0)
  • Virtual Room Connector (4.4.6)
  • Meetings Connector (4.6.3)
  • Recording Connector (3.8.41)
  • Client SDK (5.5.0)

Please note that while the minimum Zoom Client software version required for this schedule is 5.5.0, we may require additional updates outside of this release window to address additional security or compliance features. We always encourage customers to refer to our release notes for any included security enhancements.

Frequently asked questions

Why is Zoom moving to a 9-month release window?

As a best practice, customers should always be on the latest version of any software they are using as each release includes important feature updates, enhancements and bug fixes. We understand that it isn’t always possible for organizations to update all employees and need additional time for software reviews. With this in mind, we are requiring customers to update software that is more than nine months out of date.

How long will customers have to get on the new schedule once announced? What version will customers need to be on by November 1, 2021?

Beginning November 1, 2021, all accounts must be running on at least minimum version 5.5.0 for most Zoom products (Outlook Plug-in version 5.5.1, Scheduler extension version 1.6.3 for Chrome and 2.1.13 for Firefox) to be able to log into the software or join meetings. From that point on, users will be unable to log into the software or join meetings and will be prompted to update their client before using the platform should their version fall behind this nine-month window. We always recommend customers update to the latest version whenever possible to take advantage of all our latest security and functionality features. We may require additional updates outside of this release window to address larger security or compliance features

Does this new release window include all Zoom products and services (Zoom Phone, CRC, etc.) or only the Zoom Client?

Yes, this policy will affect the Zoom Client for Meetings (Windows, macOS, Linux, iOS, and Android), Zoom Rooms, Zoom Rooms Controller, Zoom Phone Appliances, Outlook Plug-in, Browser Scheduler Extensions, VDI Client, Virtual Room Connector, Meetings Connector, Recording Connector, and Client SDK.

What happens if a major vulnerability is detected and fixed? Will Zoom deploy additional updates and/or make forced updates?

In the case of an urgent security or other matter, Zoom may choose to release a forced or prompted update, and customers will have to update to the latest version of the client to be on the most secure version. Zoom reserves the right to release or push out forced, off-schedule updates to help keep customers secure.

How often will there be new releases?

Zoom releases bundled updates regularly to help mitigate backwards compatibility issues for most products, and because of these regular release cadences, there will be multiple available versions within the 9-month window. To see historic release cycles, please refer to our Release Notes.

Am I not secure if I’m not on the latest version of Zoom?

Zoom is committed to enhancing the security of its products and services, and protecting customers from external threats. We recommend users use the latest Zoom software with all current security updates. Users can easily check for updates and upgrade by visiting our website. We always encourage customers to look at our release notes for any included security enhancements. Customers can also look at our Security Bulletins to learn more about fixed issues.

What happens when customers are approaching the end of the release window and do not update in time?

Customers will be prompted to update the Zoom meeting client to the latest version before they can sign in or join a meeting/webinar if they fall behind the 9-month window, but will be provided the option to join a meeting through the web client instead. Users will only receive a notification if the Zoom client has exceeded the upgrade window. If you have prompts disabled at the device level, the administrator will be responsible for applying updates. Other products, such as the Zoom Scheduler extensions for Chrome and Firefox or the Zoom Room Scheduler, the scheduling functionality will be disabled and a warning will be displayed. Zoom will not provide troubleshooting support for products running versions outside the nine month window.

Do customers have the ability to choose which version they would like to be on?

No, Zoom only provides the latest version through the client and our website.

Will there be an option to set up automatic updates in the future?

Zoom is exploring the option to provide an automatic update process for customers who prefer to manage Zoom clients for their users.

How can customers see which versions their users are running?

As an admin or owner you can view which versions users on your account are running through the Dashboard or within the user management portal by filtering by client type. Individual users can check the version directly in the desktop client and mobile app.
