FAQ: Attaching files

Q: What happens to my file when I attach it?

A: If the conversation is posted in a community, the file is added to the Files list for the community that the conversation is posted to. To find the file, select the community, and then click Files and select the file or go to the conversation containing the file. If the file is attached to a conversation in a Microsoft 365 connected community, the file will be saved in SharePoint. Otherwise, the file will be saved in Yammer cloud storage.

Q: Can I choose where to upload a file?

A: No. If your connected group can save files in SharePoint, all new files for that community will be saved there. All other files are saved in Yammer cloud storage.

Q: Can all communities store Yammer files in SharePoint?

A: No. Even when storing Yammer files in SharePoint is available for your company, certain types of communities can only store files in Yammer:

  • Private messages

  • External communities

  • Any non-connected communities

Q: Can I add files directly in the Apps/Yammer folder in SharePoint and see them in the Files list in Yammer?

A: No. To see or search for a file in the Files list in Yammer, you must attach it to a conversation or upload it to Yammer. We recommend that you do not delete, move, or rename files in the Apps/Yammer subfolder.

FAQ: Working with files once they have been added in Yammer

Q: How can I pin a file to the home page of the group?

A: On the home page of the community, in the Pinned section on the right side of the page, click Add, and then select Add a link.

Only users who have access to the file can access the pinned file.

Q: How do other users view a file I posted in Yammer?

A: How the attachment is displayed in the feed depends on the file type. Any non-image file attachment is visible as a link under your message. Users can click the link to view the file. Image attachments are visible as a thumbnail under your conversation post or reply. To view the image, users can click the thumbnail.

People can also view and download a file from the group Files list or the YammerFiles list. Click the file, and in the right pane, in the File Actions section, select Download.

Q: Who can view files I post to Yammer?

A: This is different for Yammer files stored in Yammer cloud storage and Yammer files stored in SharePoint.

For files stored in Yammer:

  • If the file is uploaded to a public community, anyone in the Yammer network can access the file.

  • If the file is posted to a private community, only members of that community can view and edit the file. You can also share a file with people who are not community members.

  • Network level guests can view and upload files in communities they belong to.

  • Conversation-level guests can view files referenced in the conversation and can upload files to the conversation.

  • External guests can view and upload files in communities they belong to.

For files stored in SharePoint:

  • If the file is uploaded to a public community, any regular Yammer user in the Yammer network can access the file.

  • If the file is posted to a private community, regular users who are members of that community can view and edit the file. Community members can also share a file with other Yammer users who are not community members.

  • Network level guests don't have default access to view Yammer files saved in SharePoint.

    • If you want them to be able to request access to view specific files, they must be added as a Azure B2B guest on the Microsoft 365 tenant. For more information, , see Azure Active Directory B2B Documentation.

    • If you want them to be able to upload files to a specific community or have default access to files uploaded to SharePoint, add them as a community member in SharePoint.

  • Conversation level guests do not have default access to any files saved in SharePoint. If you want them to be able to request access to specific files in the conversation, add them as an Azure B2B guest on the Microsoft 365 tenant. They can't upload files.

  • External guests can only be members of external communities. External communities only store files in Yammer.

Q: How do I share a file with specific coworkers?

A: Either send a private message to those coworkers and attach the file to the message, or if the file is already listed on the Files page, click the file and then click Share.

Q: Does search look in the contents of files, or just the file name?

A: For files stored in Yammer, Yammer search includes the first 5000 characters of the most recent version of .docx, .pptx, and .pdf format files as well as metadata such as title and author.

For files stored in SharePoint, Yammer search only searches the title and author. If you need to do a content search of files stored in SharePoint, you'll need to go to the document library.

Q: How do I delete a file?

A: Only the file owner and group admins can delete a file. In Yammer, click the file, and under File Actions section, select Delete this File.

Note: Always delete the file through Yammer. Do not delete a Yammer file directly from the SharePoint document library where it is stored, or links to it will remain in Yammer.

Q: What happens to my file if I delete the message that I attached it to?

A: The file will remain stored in the group in which you posted the message. If you want to delete it, click Files, click the file, and then under File Actions, select Delete this File.

Q: When my company starts using files stored in SharePoint, what happens to files we already have in Yammer?

A: There are no changes for non-connected communities. For connected groups, existing files stay in Yammer cloud storage and are made read-only. All new files in connected groups are stored in SharePoint. This means that to edit a file that was previously stored in Yammer, you'll need to upload the file again. All future revisions will be stored in SharePoint. For more information, see Edit a previously uploaded file when your Yammer connected group stores files in SharePoint.
