Details

Summary

Viva Engage mobile app will reduce reply notification volume by only notifying users of direct involvement (starting conversations, direct replies, @mentions). Automatic subscriptions from reading, commenting, or reacting will stop. The update rolls out worldwide from July to August 2026, requires no action, and keeps existing admin controls unchanged.

Body (from Message Center)

[What and Why:]

Viva Engage is updating how reply notifications are delivered in the mobile app to reduce notification overload and improve notification relevance. Users will continue receiving notifications for conversations that directly involve them while unnecessary notifications from high-volume community discussions are reduced. This improves productivity by helping users focus on the notifications that matter most.

[Rollout Schedule:]

General Availability (Worldwide): Beginning in early July 2026; expected to complete by late August 2026

[Impact on Your Organization:]

Who is affected:

Viva Engage mobile app users.
Organizations using Viva Engage communities.

Platforms/Services:

What will happen:

Users will receive reply notifications when:
- They start a conversation.
- Someone directly replies to their post or comment.
- They are @mentioned.
Users will no longer be automatically subscribed to all future replies in a thread simply because they:
- Read a conversation.
- Commented on a conversation.
- Reacted to a conversation.
Community subscribers will continue to receive notifications for new posts (thread starts).
Community announcements will continue to generate notifications.
@mentions and direct replies will continue to generate notifications.
The change is enabled automatically as part of the service update.
There are no new tenant settings, policies, or administrative controls.
Existing admin controls and notification settings remain unchanged.
