Add your mailbox to iPhone, iPad and Mac
Add a mailbox to the built-in Mail, Calendar and Contacts apps as an Exchange account, and it stays in step with the web.
Set up with a profile
On the device, open your account page, choose the mailbox and install the profile. It carries its own app password, so the device doesn't ask for one.
Or add it by hand
Add an Exchange account with the mailbox's address and an app password. With your domain's Autodiscover record, that's all the device needs.
In step with the web
Read, send, flag, move and search, from the mailbox's address or its aliases. Moving a message moves its whole conversation, as it does on the web.
In your control
Revoke an app password or sign a device out, and it stops syncing within a minute. Remove the account from an iPhone or iPad remotely, and nothing else on it is touched.
Run your team's email in Mail
Every Business plan includes it, with Calendar, Contacts, Drive and the rest of your workplace.
