Viewing outlook-attachments in Sharepoint

Question

When I store a mail with attachments from outlook in Sharepoint, I'm able to read the mail and can see there are attachments, but I cannot open attachments.
After syncing it with Explorer, it's possible to open them in Explorer, but I'm looking for a way to open them online. Does anyone have a solution? I know you can store the attachments separately, but that's not the way I want it.

Answer 1

AFAIK, Microsoft has not developed features to open attachments from a .msg file stored in a library. Just like you say, The SPO preview of an email shows the presence of attachments but they cannot be opened without downloading the email and then using the local email client (e.g. Outlook) to open the attachment.

3rd party apps will be needed to do so. Here is a thread with similar question: https://techcommunity.microsoft.com/t5/sharepoint/drag-drop-msg-into-document-library-cannot-open-attachments-nor/m-p/449949

And you can vote in UserVoice to make Microsoft know your feeling about it.

Answer 2

There are 3rd party apps that extend the OOTB functionality of SharePoint in a browser by offering email previews that also allow opening of the attachments in a browser (e.g. pdf file or another email). e.g. here

Email attachments need a location to be processed. And then, attachments should be presented via a link. Without a processing location/Document Library in SharePoint, natively email attachments can not be displayed. As mentioned in above comments, there are third-party add-ins that does the job. All of them, use a temporary location (Document Library) in SharePoint to display the attachments. However, following add-in has more benefits than just previewing the emails with attachments. https://fleximal.com.au/products-services/sharepoint-online-search/

It even recursively go inside the email attachment. For example, if there is an email attached inside an email, it will render the second email as well.

Answer 4

Sharepoint has (recently) made a change in how archived / saved emails (.msg file format) are displayed. An email with an attachment will now no longer show the attachment when you double click the file if the file is saved in Sharepoint. If WILL do so in a normal file folder. It ONLY works (if in Sharepoint) if you open with the Outlook App. Additionally, you need to specify each and every time to use the App to open the file. This is NOT user friendly at all.

As Gregory posted the out-of-the-box SharePoint preview does not allow viewing of the email attachments in the browser. The simplest way is to download the email and open the downloaded file using Outlook. Using OneDrive for Business client is another way to open the file on the local client. There are SharePoint apps that provide this functionality in the browser (example, https://www.slimapplications.com/product/email-manager/)
