Set up Outlook for Mac
The following steps use the fictitious email address user@example.com.
Be sure to replace any occurrence of the above with the user portion, domain portion, or complete email address of the mailbox which you are adding to Outlook.
Always use lower-case letters for your email address, or login username.
You will be presented with one of two options to set up a new account, depending on whether you're setting up your first account within Outlook, or adding one to the existing list.
Option 1: First Outlook email account
If Outlook correctly identifies your address press [Add user@example.com]
Otherwise press [Add Others]
Option 2: Additional Outlook email account
Open the [Tools] tab, then press [Accounts]
Either add a new account via [+] then New Account
Or add a new account by pressing [Add Email Account]
Enter the email address of your new mailbox, all in lower-case letters.
Press [Continue] then [Choose the Provider]
Press [IMAP/POP]
Enter your email address in both the [Email Address] and [Username] fields, in place of user@example.com
Enter your given password carefully. It is CaSE senSITive, so type with care.
Complete the details, as per the screen shot below.

The following window will appear.
Enter / correct the name you wish to be displayed in the From field, when sending to recipients in the Full name field.

Don't be concerned about disabling the saving of Sent messages. In the following step, you will instruct the SMTP server to do so.

Under Outgoing Server press [More Options...]
The following settings instruct the SMTP server which sends your email, to save a copy to your Sent folder.
By preventing Outlook from uploading your Sent message in the previous step and instead relying on the SMTP (sending) server to do so, you're halving your bandwidth use when sending messages and speeding up the process at the same time.
For Authentication select User Name and Password
Enter your email address with a slight modification, appending the string +sent after the user portion of your email address.
The below assumes your email address is user@example.com.
If your email address were sam@greeneggsandham.com you would enter sam+sent@greeneggsandham.com.
Enter your mailbox password, as you did when adding the mailbox.
Press [OK]
At this point, your mailbox is configured.
You will see your INBOX, along with the various default folders.
The steps which follow below should be completed in order to test the customised SMTP (sending) feature.

Press [Send]
Review the Sent folder, possibly waiting a few seconds for the message to appear.
Right-click on the message and select View Source
A new window will appear, showing the message's envelope details.
These details include the To, From and other fields of the message, as well as other information about the message, including which servers have handled it and recipient and authentication details.
Review the message, looking for the email address which you have recently configured, paying attention to the highlighted items below.
In particular ...
Find the top-most Delivered-To field - it should include the +sent string, before the @ sign.
Find the bottom-most Original-Authentication-Results field and confirm that your email address, with the +sent modification is shown immediately after smtp.auth=.
