Pros
Pro Integrates with cloud storage services
Microsoft Outlook comes with built-in cloud storage browser allowing you to attach files directly from services such as Dropbox, Box, Google Drive or OneDrive to emails and directly open attached files without the need for the main cloud storage app.
Pro Good built-in contacts
In addition to showing contact information, the People section of Outlook can show all conversations you've had with a person. Moreover, if you're looking for someone that's not in your contact's list, but is in your company's or school's directory, Outlook can pull that information through integration with Global Address List (GAL).
Pro Features that help to prioritize emails
The app will automatically attempt to figure out which emails are important to you and put them on top. The priority emails will show up in your inbox in a tab called Focused, with other emails in a tab called Other. It aims to separate the important emails from spam and promotional newsletters.
Pro Smart lookup
Smart lookup is a feature where the Bing search engine is bundled in the app to allow users to automatically search for relevant websites, information, and images based on the word highlighted by users, without the need to open external browsers. The results will be shown on the right pane of the window.
Cons
Con Doesn't follow security guidelines
The app stores user information and credentials on outside servers which is a violation of ActiveSync password requirement policies. These security concerns have been enough of an issue that European Parliament has banned its members from using the app out of fear that it might lead to leaking sensitive information.
