Make sure everything has uploaded then grab the Dropbox app for iPhone and you'll be set. Or, if you use Dropbox, the other big, cross-platform popular option, same applies. With this, you just need to install the OneDrive app from the App Store and you'll have instant access to all your photos wherever you are. You can also upload your iPhone photos to OneDrive, so you don't have to switch from what you're familiar and comfortable with. If you didn't have it set this way, there's still time to do so and upload your entire photo library to Microsoft's cloud. If you've been using Windows 10 Mobile then there's a strong chance you had your phone set to auto-upload your photo library to OneDrive. You can opt to start fresh, or better still, backup all your photos to your computer and your favorite online service, and then go from there. (Apple uses the iCloud Photo Library service instead - for a price.) Not least because on Windows Mobile you may have been using a microSD card to store them on, something not supported on the iPhone without needing extra peripherals and apps. Our recommendation would be to avoid transferring your photo library from your old phone to your new one. It's considered by many to be the best mail client on iOS, so it's worth checking out. You also have the option of using the Microsoft Outlook app on your iPhone to manage your Outlook email and calendars. Your Microsoft account will pull in your email, your contacts and your calendar to the relevant stock apps on the iPhone. Tap the Notes switch to turn on and sync your iPhone's Notes content, which will appear in your email account under Notes.
