Email settings for Miller Salsbury 2017 on the new Office 365 via Rackspace.

For setting up the email on your personal computers, please give me a call and I'll give you help remotely.

For setting up the email on your mobile devices I would suggest the Outlook app for your device, but I am providing a long screenshot for the setup on iOS with the built in email.  I think the app is going to be the far easier set up.  Because of the server change, you will want to make sure you choose Office 365 during setup.  The apps may give you several choices.

Android
Microsoft Outlook

I'll try to add some screenshots for the Android app as soon as I can.  I found that simply putting in the email address found the correct server.

iOS
Microsoft Outlook

If you use the built in email client on your iPhone or iPad, you can also set it up there.  My suggestion would be to remove the previous email settings before trying to add the ones.  If you accidentially used the previous email, hosted by Uptime, those messages will be lost once that server is shut down at the end of the month.
