Adding Recipients

To add recipients do one of the following:

• As you type in the To field, Outlook Web App will display matches it finds. Click on one of the matches to add that email address to your message.
• Clicking on To (or Cc or Bcc) will bring up your Microsoft 365 My contacts list and allows you to add recipients.
• Searching My contacts returns matches from both your personal contacts and the University's people directory.
• Use the Cc field to send a copy of your email to one or more additional recipients.
• You can add the Bcc field by clicking the ellipsis above the message. From the menu, click Show Bcc.
• To remove a recipient before sending the message, click the x next to the item you want to remove.
• Multiple email addresses must be separated by semi-colons (e.g., TestMail1@Ilstu.edu; TestMail2@ilstu.edu).

Adding Attachments

You can attach files to your email by clicking the Attach button above the message. This allows you to attach files stored in OneDrive or on your local computer (See figure 2).

 Figure 2:

• You can also attach files by dragging and dropping them directly into the body of the message.
• To remove an attachment before sending the message, click the x next to the item you want to remove.
• The size limit on sending email in Microsoft 365 is 50MB. This size limit applies to the message contents itself, as well as any attached files.
  • For Files over 50MB, we recommend using SendTo, our secure emailing software. For more information on SendTo, see: How to drop off and pick up files in SendTo
