Click on Start and type 'run' and hit enter. Type 'outlook.exe /manageprofiles' and press enter.
3. Click on the 'Email Accounts' button
6. Select the 'More Settings' button from the lower right of the window
7. Click on the 'Advanced' Tab
8. Ensure that the 'Incoming server' is set to SSL/TLS and the port is 993 (IMAP) or 995 (POP3)
9. Ensure that the 'Outgoing server' is set to STARTTLS and the port is 587 (or SSL/TLS and port 465)
10. Testing the account should work as expected (simple way is to send an email to someone and verify it moves from the outbox to the sent items)
Other email clients will need to be configured per their own instructions. Please find the configuration guide (Google is a great resource!) for your specific mail client to configure and enable security using SSL/TLS.

IOS Mail automatically uses the correct settings for many email services. That's why you seldom need more than your email address and password to set up an email account on your Mac or your iPhone, iPad, or iPod touch. If Mail needs more information, Here are the recommended settings:
|Name of setting||Setting (Examples)||Description|
|Full Name||Bill Smith||Choose your sender name as you would like it to appear in messages that you send. Example: John Appleseed.|
|Email Addressfirstname.lastname@example.org||Your email address for this account, such as email@example.com.|
|Incoming mail server settings|
|These settings are for downloading messages (receiving email) from your email provider's mail server.|
|Account Type||IMAP||Choose IMAP*, POP, Exchange IMAP, or Exchange EWS1, as directed by your email provider.|
|Description||MyEmailAccount||Choose the name that Mail will use for your account, such as Work, School, or Yahoo.|
|Incoming Mail Server (host name)||mail.yourdomain.com||The host name of the incoming mail server, such as mail.example.com.|
|User Namefirstname.lastname@example.org||Your full email address for this account, such as email@example.com.|
|Password||MySecurePassword||The email password you use to sign in to your account.|
|Port||993||The port number used by the incoming mail server. Common port numbers for incoming mail are 993 for IMAP accounts, and 995 for POP accounts.|
|Authentication||Password||Choose Password, MD5, NTLM, Kerberos, or None, as directed by your email provider.|
|Does the incoming mail server support SSL (Secure Sockets Layer) or TLS (Transport Layer Security) encryption?|
|Outgoing mail server (SMTP) settings|
|These settings are for uploading messages (sending email) to your email provider's mail server.|
|Outgoing mail server (SMTP)||mail.yourdomain.com||The host name of the outgoing SMTP (Simple Mail Transfer Protocol) server, such as smtp.example.com.|
|The port number used by the outgoing mail server. Common port number for outgoing mail is 465 (or sometimes 587)|
|Use SSL?||Enabled/Yes||Does the outgoing mail server support SSL or TLS encryption?|
|Authentication||Password||Choose Password, MD5, NTLM, Kerberos, or None, as directed by your email provider. If None, you may need the additional settings below to send email when you're on a different network, such as from a Wi-Fi hotspot or Internet cafe.|
* IMAP (Internet Message Access Protocol) is best if you check email from multiple devices, because your messages are stored with your email provider until you delete them. As long as your devices can connect to your email service, your mailbox stays the same on each device. If you use POP (Post Office Protocol) on more than one device, those changes don't appear on every device, and new messages delivered to one device may not be delivered to your other devices.
Note: If you are migrating from another provider, they may not have valid SSL certificates for your domain. This will result in a warning:
Simply click 'Yes' to continue using the server. This will be resolved once the DNS and email migration is complete.
