Today, when someone receives an email in Outlook on the web with a Word, Excel or PowerPoint document attached, Outlook shows the possibility to edit the document (Edit and reply). Users can edit the document/attachment directly in Outlook on the web, via Office on the web.
The option will be removed at the end of June. Instead, users will have to download the documents or save them to OneDrive. It is also recommended to share the document via a sharing link, instead of adding the document as an attachment.
