If your organization relies on Viva Engage for daily conversations and community engagement, here’s something you won’t want to miss. Microsoft has scheduled a series of planned maintenance that will temporarily limit what your organization can do in Viva Engage. Let’s delve into what will happen in Viva Engage and how it’ll affect your organization.
What’s Changing During Viva Engage Maintenance
Microsoft has planned this maintenance to enhance the reliability and performance of Viva Engage. While maintenance is underway, Viva Engage will switch to read-only mode.
During these times, you can browse posts, communities, storylines, and messages, but won’t be able to make changes. In clear, you won’t be able to:
- Create new posts
- Reply or react to conversations
- Post to your storyline
- Create or edit communities
If you try, you’ll see error messages like:
- Your message wasn’t posted, please try again soon.
- Sorry, something went wrong, please try again soon.
📅 Viva Engage Planned Maintenance Schedule
Microsoft is spreading maintenance over three Saturdays in September 2025. Each maintenance window will last about 12 hours starting at 16:00 UTC:
- Saturday, September 13, 2025
- Saturday, September 20, 2025
- Saturday, September 27, 2025

🏢 Timed with Your Productivity in Mind
Microsoft has scheduled this maintenance outside typical business hours to minimize disruption. However, given the global nature of many organizations, some users may still be affected. So, it’s recommended to inform your regional teams in advance to ensure proactive measures and avoid unexpected interruptions.
