If your company uses Microsoft Exchange or Microsoft Outlook to provide you with email service then you can access your emails using your mobile phone without using any apps.
Accessing Emails from Phone with Office 365
If you have an account setup with Office 365, visit https://outlook.office365.com/owa/ from your mobile phone to access the secure login page. The link takes you to an official website hosted by Microsoft Office 365.
Once there, enter your company email address. The site will then take you to your company specific website where it will ask you for your login credentials. Enter your password and you will be able to access your emails and calendar from your phone.
Accessing Emails from Phone through Microsoft Outlook Web App (OWA)
If your company is not setup for Office 365 yet and just uses Microsoft Exchange Server to provide email service then do the following:
Visit https://webmail.[yourcompany].com/owa. Replace [yourcompany] with the domain name of your corporate site. If this doesn’t work, open your Outlook using a computer and click on File, then look for Account Settings under which there is a link for accessing the account on the web. Type in that link in your phone and enter your login credentials.
That’s it! Bookmark the page in your phone’s browser and you can access your emails from anywhere.
