OWA Webmail is an iOS mail client app. It can connect to an Outlook Web App (OWA) server.

What is an OWA server? If you have access to a Microsoft Exchange server you usually use Microsoft Outlook on your desktop PC. This connection is through an internal net. If you are on the go you usually are not able to use Microsoft Outlook. There is an extension to Microsoft Exchange server to give access on the internet through a web interface (webmail). This interface is called Outlook Web App.

OWA Webmail uses this web interface to access your mail on your iOS device, so you do not have to concern yourself with IT security issues and protocols. The app does not sync anything with your device, all messages, contacts etc. remain on your server.

NOTE: It is not a general webmail client, so you cannot use it for Gmail, Hotmail, Yahoo mail etc.

IMPORTANT NOTE for OFFICE 365 users: The app uses the light version of OWA, so "Outlook Settings", "Options", "General", "Outlook Web App version", "Use the light version of Outlook Web App" checkbox must be checked.

Supported OWA versions at the moment:
- Outlook Web App 2010 (tested with version
- Office 365 (tested with version

NOT SUPPORTED by current version:
- attachment upload
- features that are not supported by OWA ligth interface

Crashes every time I open it

Downloaded this to have access to my work email from home. Every time I click on the app, my screen flashes bright white and takes me back to my home screen... super annoying. For reference I have an iPhone 11.

Crashes every time I open!!

I use this app for work and since I’ve upgraded my phone to the iPhone 12 pro max, it crashes every time I open. The version I’ve downloaded is the latest and I don’t understand. It worked perfectly on my 8 plus.

Zero stars

I have never rated an app this low; not even close. Will not open attachments, even in paid version. All the icons/links to functions, which are supposed to be at the bottom of the screen are missing. Support (help) function is useless. Can’t start a new email.
