Device & OS
not provided
Scenario
Creating new posts or announcements within Yammer or Viva Engage communities.
Observed behavior
The image upload icon is completely hidden from the post creation interface, preventing users from attaching any images to their messages.
Before you start

Verify if you have community or network administrator privileges, as modifying global file upload restrictions requires administrative access.

Solution 1Recommended

Enable File Uploads in Network Admin Settings

Apply this solution if the image upload icon is missing across all communities, which usually indicates a network-wide restriction.

Yammer and Viva Engage allow network administrators to restrict file uploads. When uploads are disabled globally, the image attachment icons are hidden for all users across the platform.

1
Access network settings

Log into your Yammer or Viva Engage account, click on the Settings gear icon, and select 'Edit network admin settings'.

2
Open configurations

Navigate to the 'Configurations' tab located in the administrative menu.

3
Adjust file upload permissions

Scroll down to find the 'File upload permission' setting.

4
Allow all formats

Change the setting to 'Allow people to upload and attach files in any format' and save your changes.

Enable File Uploads in Network Admin Settings
Changes Applied: Once the configuration is saved, users may need to refresh their browser or restart the app for the image icon to reappear.

Frequently Asked Questions

Why is the image upload icon missing in only one Viva Engage community?

If the issue is isolated to a single community, it usually means the community lacks a functional connected SharePoint document library, which is required by Viva Engage to store uploaded files.

Can regular users bypass restricted network file-upload permissions?

No. If a network administrator has disabled file uploads in the global Viva Engage configurations, regular users cannot bypass this restriction to upload images.

Does using an external home network affect image uploads in Yammer?

Accessing the service from an external home network generally does not disable the upload icon itself, but strict corporate VPN policies or firewall rules might block the actual upload process.
