Hi CDV_JHC,
Thanks for the information.
I am guessing your account is set to standard releases which means you’ll receive the updates when they're released broadly to all customers. To confirm, I checked two different user accounts in my tenant, one is set to Standard and another to Targeted releases.
The user whose account is set to Standard release does not have zoom either at the bottom right corner or in View menu, as shown below.
User’s account set to Targeted releases, can see zoom option in both the places, screenshot in my first reply.
Standard release: This is the default option; users receive the latest updates when they're released broadly to all customers.
Targeted release: With this option, users can be the first to see the latest updates and help shape the product by providing early feedback. Tenant admins can choose to have individuals, or the entire organization receive updates early.
According to this support article, Zoom button in the menu ribbon under the View tab is mentioned as Coming Soon. I also checked What's new in Excel for the web which lists all the features that are released but Zoom is not mentioned in the list. I believe, it is not released for all the customers yet. But don’t worry, as this feature is available to Targeted release users, I am sure it will be released for other users soon.
Meanwhile, please use Ctrl + mouse wheel to zoom in/out of the workbook.
Kind Regards,
Neha
