Attach files in Outlook

You can drag a file from File Explorer or your computer desktop into your message body to attach it. Or you can follow the steps below:

1. In classic Outlook, in a message, meeting, or reply you're composing, select the Insert tab, then select  Attach File.

2. Choose a recent item from the list, or select a Browse option at the bottom of the menu to navigate to the file you want.

3. Navigate to the file, then select it and choose Insert. (Use Ctrl+click if you want to select multiple files.)

Tip: If you select a cloud-based OneDrive or SharePoint file to attach, you'll have the option to share or attach the file:

• Sharing gives all recipients access to the cloud-based file. Any comments or edits to the file made by one recipient are visible to all of them.

• Attaching gives each recipient an identical personal copy of the file you've attached.

1. In Outlook for Mac, in a message, event, or reply you're composing, select choose  Attach.

   If you don't see Attach, select the ellipsis (...), choose Customize Toolbar, and drag Attach to the toolbar. 

2. Navigate to the location where the file you want to attach is stored. 

3. Select the file, then select Choose.

Tip: You can also drag a file from your computer, OneDrive, or the cloud into a message to attach it. 

1. In new Outlook, in a message or reply you're composing, select the Insert tab, then choose  Attach file. 

1. (For an Event, you'll find  Attach under the body of the meeting.) 

2. From the menu, choose a location to browse for the file, or select a suggested file.

3. Navigate to the file you want to attach. Select Open (or Share link).

Tip: Outlook gives you the option to share link or to attach the file:

• Share link saves the file to OneDrive (if it isn't already) and gives all recipients access to that cloud-based file. Any comments or edits to the file made by one recipient are visible to all of them and to you.

• Attaching gives each recipient an identical personal copy of the file you've attached.
