Pardon my frustration.
Read many different posts and responses to this.
Microsoft documentation instructs you to click on the Preview Button to view your attachment document.
No button in Attachments.
Click on any type of document to View and it immediately downloads. Nobody wants that.
Just need to View the document. Whether its a PDF, Office doc, jpeg, email...just want to view it.
Read Adobe Chrome Extension should work PDF's, tried that, doesn't work.
And the Office Editing Plugin for Chrome should work for 365 documents, that doesn't work.
Attach to SharePoint and create a link? More code required.
Or Download to OneDrive? Most of these documents are being uploaded from these locations, why do I want to download them again and have multiple copies across users OneDrive's?
Am I missing something? A Microsoft App that won't open office documents Read Only or in Preview Mode from another Microsoft App in a browser?
Or I have to pay for another app just to Preview?
Anyone...
