I have Opera mini hifi oem nokia v. 4.5.40312 20150407. I can't send emails, let alone photos from my Hotmail account. Can't change settings to ones given by Microsoft. Can't send emails with photos from outlook.com. Can't get gmail to accept my details so can't even get into that service.
I've looked at settings for Hotmail and gmail and all are different from those given by Microsoft. I'm glad I can still read emails using mail and that I can send photos via messaging. I like my Nokia as it's simple, but loss of usability is depressing. Nokia Express is much missed.
