TL;DR:
Microsoft have announced their plans to rebrand Yammer into Viva Engage to provide a consistent experience. This change will happen everywhere Yammer surfaces; web, mobile, and integrations (Embed, SharePoint and Outlook). Logo, app icon and name changes now due from 3rd April and continue throughout 2023.

Details:
Microsoft: “Notifications will be updated to the Viva Engage name and icon, a reference to Yammer will remain until later this year.

All Yammer references in the app will be updated to Viva Engage, and there will be a pop up informing the change as well as a banner directing users to the public blog post about the rebrand with more information around what’s changing and the timeline.

There will be no impact to the existing profile, posts, bookmarks, etc. All rebranding updates don’t require additional actions; changes will be automatic. Outside of branding changes, there are no changes to the features, capabilities and investments for Microsoft 365 customers. You will continue to experience and benefit from the power of Viva Engage just as you did with Yammer”.

Availability:
Generally, starting late February into March 2023. More changes due later.
Generally, starting 3rd April 2023. More changes due later.

The first stage of this rebrand happened last year with the rebranding of the Yammer Communities app for Teams into Viva Engage.

Late February 2023 From 3rd April 2023 MS will add an in-app banner with relevant information around the switch. At the same time, the app name in the Google Play and App Store will be updated to “Yammer (Viva Engage)” and there will be no change to the installed app name or icon. Searching “Yammer” will continue to display the app as the top result.

The rest of the rebrand will occur incrementally, starting with the mobile apps (iOS & Android) and the Communities app for Outlook updating their app icons and name in March 2023 from 3rd April 2023.

In mid-to-late March From 3rd April, the installed apps will update to the “Viva Engage” name and icon, updates may be automatic depending on your settings.

MS will communicate other endpoints like the web and embed experiences as they make progress.

*I know other sites beat me the theme of that title, but as its origins are from the 15th century, I’m sure they won’t mind. Also, I’m not sure I needed the ‘long’ before the lower-case Italian ‘viva’…it just reads better that way 😊
