When sending an email, its easy to attach a file, such as a photo, document, PDF, spreadsheet, and more.

Whether youre composing a new message, replying to a message, or forwarding a message, you can attach one or several files.

Select your file from Recent Items, Browse Web Locations, or Browse This PC.

A copy of this file is attached to your message and will be sent along with it.

Or, for an existing message, click Reply, Reply All, or Forward.

In the message window, go to the Message tab, then, in the Include group, click Attach File.

Or, drag files from folders on your computer and drop them on the message window.

These instructions apply to Outlook for Microsoft 365 for Mac, Outlook 2019 for Mac, Outlook 2016 for Mac, and Outlook for Mac 2011.

In your message, go to the Message tab, then select Attach File (the paper clip icon).

By default, Outlook does not send email messages with attachments that exceed 20 MB.

If the file doesnt exceed 25 MB, its possible to increase the Outlook attachment size limit.
