Inbox Pro is designed for maximum compatibility with Outlook / Exchange servers that do not support the official Outlook App by Microsoft.

We use many tricks to talk to the old, outdated, or just problematic Outlook/Exchange servers that many companies are unfortunately asking their employees, staff, or students to use.

If this is your company, download Inbox Pro and view, compose, and send emails with an interface designed to be the perfect fit for iOS 10 on both iPhone and iPad.

Ratings and Reviews

iOS 11


Only app that works for me due to use of two factor authentication. Unfortunately, since iOS 11 much of it is buggy. Really hoping for an update to correct some of the issues like the inability to open attachments now.

I’m having issues opening documents on my iPad Pro. Works fine on my 6s iPhone.

Best of the pile, but buggy and frustrating


I've reviewed several of the Outlook screen scrapers here in the app store, and I have to say that this one is the best of the bunch. It does a good job of recognizing the exact Exchange configuration that the server is using, and it provides the basic functionality needed. Now, if only the developer CARED about customers...

My biggest complaint is that it routinely loses my configuration, resulting in my having to connect it again and save the configuration. Not a huge deal, but it sometimes happens multiple times in the day. It's at least once a day on regular occasion. I have contacted the developer, through his own tool, to report the bug and have received NO RESPONSE back. No fix either. I've even sent in crash logs to him. Nada. Clearly, he doesn't care about fixing the problems, or even just responding to customers. That doesn't bode well for fixing any future bugs, does it?

The app provides basic email reading and responding capabilities, but you can't look into the calendar details for any appointment. You can't create new appointments. You can't look into the GAL (Global Address List), but it does remember some people if you reply to them. All in all, it's a four star app. However, with the lack of respect from the developer, well, you get only one star.
