Using Gmail from Outlook

By default, Gmail accounts do not allow IMAP or POP3 access, and so can't be used in Microsoft Outlook either way.

To enable:

1. Log into https://gmail.com.

2. Click the Settings icon.

3. Choose Settings.

4. Under Forwarding and POP/IMAP, choose to enable POP3 and IMAP as required.

5. Click Save Changes.

6. Next, visit https://myaccount.google.com/security?pli=1#connectedapps.

7. Set Allow less secure apps to ON
