NEW Outlook app: how to add an IMAP account with user name different from email address?

Hi phoyer

Greetings!

Thank you for posting in Microsoft Community.

We understand that you need help with this concern. We will work together to achieve your desired resolution.

For me to better understand the issue, I’d like to ask a few questions:

• What is the version and edition of your Outlook app? Go to File > Account > Product info (ex. Microsoft 365 for Business).
• Can you please provide us a screenshot of the things that you want to achieve on your end?
• What is your email domain name? ex. @Yahoo.com

Are you referring to the screenshot I have provided below?

We look forward to your reply.

Sincerely

Hi Juhn,

I am referring to the "NEW Outlook", the Outlook version is 1.2023.927.10 and the client version is 20230922005.15.

As your screenshot shows, in the classic Outlook you can just specify the authentication name, in the new preview version this is missing:

The screenshot is Italian but generally, for IMAP you can only specify the password whereby for SMTP you can specify both, user name and password. As the email address is checked for correct format, so I cannot just put the user name as mail address.

Hi phoyer

Thank you so much for the screenshot.

I understand the convenience of having the option to edit Outlook usernames and I suggest that you should provide feedback about the new Outlook for Windows so that our engineering team can address this concern as soon as possible.

This is really really annoying. All my family email addresses have different IMAP login user names from their actual email addresses - just how the hosting provider sets them up and now we cannot use Outlook as there is now way to actually add these types of accounts. How can Microsoft miss something as obvious as providing a user name box??

Is there any indication when this might be fixed?

I have the same problem. I can't set a Display name different from the email address. Honestly, I find it incredible that they haven't included this "basic" field in the Desktop version.

Furthermore, through the New Outlook Desktop App, it's not possible to leave feedback. They are pushing us to switch from the Mail app to this one.

The version is:

You have Microsoft Outlook Version 1.2023.1011.100 (Production).Client Version is 20231013005.12 .
