Use iCloud+ Custom Email Domain with Outlook for Windows

Hi Ben,

Thank you for your support, because the domain is used as an alias for icloud that steps do not resolve the issue. I experimented a bit, I found the solution (if anyone else on the web is searching for it):

1. in Outlook go to Settings/Accounts, choose the icloud account, and then click account settings
2. choose in account settings the option "manage profile", and then "email account"
3. select the icloud account, and click on change/edit
4. in the "email address" field enter the email with the custom domain from icloud; in the field "username" leave your standard icloud email address; and generate from appleid.apple.com a new app-specific password.

After clicking next, and after Outlook verifies the server data, Outlook uses the custom domain to send and receive mails. Also all mails sent to the standard icloud email address are also received.

The expected strategy that should work is using (IMAP) settings:

• Incoming
  • Server name: imap.mail.me.com
  • Port: 993
  • Username: Your custom domain Apple ID email address
  • Using app-specific passwords
• Outgoing server:
  • smtp.mail.me.com
  • Port: 587
  • Username: Your custom domain Apple ID email address
  • Password: Use the app-specific password that you generated when you set up the incoming mail server.

However, somehow this won't let you establish connection, and apparently with iCloud+ Custom Email Domain according to this thread "you should use your iCloud email address here to authenticate, not your custom domain address". As well as StefanKitanovski advised, you should change the the "email address" field with the custom domain from iCloud only after your set up the account with the original iCloud email Address. However, for Mac users this is only possible in the old Outlook App. As soon as you use the 'New Outlook', the account settings don't let you change it.

Where can we request Microsoft to port this feature which existed in the old Mac Outlook App to the new one??

As a mac user of the new outlook app I want to be able to change the email address field in the settings, such that I can use an alias email address like I could in the old app (in this particular case my iCloud Custom Domain address)

I got this to work just fine, using IMAP and my username @icloud with email address @customdomain. However, I have 2 custom domains, and in my case I can add the IMAP twice, which then leads to double everything. Furthermore, the first IMAP I added worked perfectly, in terms of showing my email address, but my "full name" is my email address and I can't seem to edit it. The second email address I added is annoying in that it actually works fine, but in Outlook it shows up as my iCloud address despite setting it up exactly as I did with the first account. Again, shows up as @icloud.com when composing, but the email received is the custom domain address.

I tried to get smart by adding both addresses separated by commas (like Apple Mail does) but that didn't do it either. I don't really want to mess with double everything either, so not sure I'll use Outlook until Microsoft somehow makes Outlook work better with iCloud+ custom domains.

There is no option on a Mac to get to the option "manage profile".

The solution for Windows is super!

so is there a solution for mac office 365 :)
