Can't share files in a large group chat or meeting chat

Symptoms

When you try to share files in a Microsoft Teams group chat or meeting chat that contains more than 50 participants, the message might not be sent successfully when you select Send .

Cause

This issue occurs if the default setting for file sharing is People currently in this chat. In this case, the Specific people link is used. However, Specific people links aren't recommended when you want to share files with more than 50 people.

Workaround

To work around this issue, follow these steps:

1. Select the file's current sharing setting. For example, select People currently in this chat with the link can edit, as shown in the following screenshot.

   Note

   Selecting this setting opens the Sharing settings dialog box.

   

2. In Sharing settings, select one of the following settings:

   • If there are people outside your organization in the chat, select Anyone.
   • If all the people in the chat are inside your organization, select People in your organization.

   Note

   If the desired setting is disabled, contact your organization's administrator to change the sharing settings. For example, admins can follow these steps to enable the People in your organization setting and make it the default sharing setting:

   1. Sign in to the SharePoint admin center by using an account that has admin permissions for the organization.
   2. Select Sharing.
   3. Make sure that the People in your organization links aren't disabled.
   4. Under File and folder links, select Only people in your organization.
