If you are travelling outside the UAE and need to continue accessing your emails via Outlook Email Client, you may need to change the configuration as follows:
Outlook Email client (EIM):
1- Change setting: tools -> email accounts -> view or change existing e-mail accounts.
2- Change the email server
3- Set outgoing mail server (SMTP) to exmail.emirates.net.ae
4- Under more setting, select Outgoing Server tab
5- Check ‘My outgoing server (SMTP) requires authentication'
6- Select ‘Use same setting as my incoming mail server.’
Email works everywhere in and out of UAE. Therefore customer can keep the same in UAE
