I'm using a Nexus 5 running Android 4.4.4, and when I try to setup my company's email through the Email Android app I get the following error.
No certificates found
The app Exchange Services has requested a certificate. Choosing a certificate will let the app use this identity with servers now and in the future.
You can install certificates from a PKCS#12 file with a .pfx or a .p12 extension located in external storage.
And there's an Install button to choose a file from my SD card.
The thing is, I don't know what this file is nor where to get it. And I don't even know why should I provide it, since I've done this same configuration before in older smartphones I had. Did someone experience the same issue? How would I be able to solve it?
