Collaborate on attachments in real time
With OneDrive, you can upload an refreshed version of an email attachment at any time. Use the drop-down menu on the attachment to either upload a revised version or save a new version. For more information, see Attach a file to an email in Outlook for Windows.
Keep your Outlook add-in open while you work
Many Outlook add-ins, such as Outlook Customer Manager, offer a task pane on the right side of the Outlook window. However, when you wanted to return to Outlook, that task pane would disappear. Now, you can keep that task pane open all the time, even when you're not working in the add-in.
Easier background removal
We've made it easier to remove and edit the background of a picture. Outlook automatically detects the general background area; you no longer have to draw a rectangle around the foreground of your picture. The pencil for marking areas to keep or remove can now draw free-form lines, rather than being limited to straight lines.
