Hello everyone,

I've been struggling with this issue for months now and haven’t been able to find a solution.

When I send an email, like a quotation, to a client from Odoo, everything works as expected. However, when the client replies to our catchall email address (e.g., catchall@mycompany.com), I can see the reply correctly in Odoo. 

The problem arises when Odoo forwards the email to my personal inbox in Microsoft 365 Outlook—the display name shows up as "Admin" instead of the client's name.

Here’s what I’ve tried so far:

1. Modified the "From" field in the email template: I’ve used various configurations to ensure the customer’s name appears, like:

   {{ object.partner_id.name }}" 
   

   Despite these changes, the emails forwarded to Outlook still show "Admin" as the sender's display name.
2. Cleared any cached contacts in Outlook: I removed any saved contacts or autocomplete entries that might be causing Outlook to associate "Admin" with our catchall address.
3. Verified the mail server settings: I made sure that the outgoing mail server is correctly configured, and our catchall email address is properly authorized.

It seems that Microsoft 365 Outlook is overriding the display name with "Admin" because it’s within our organization’s domain, but the email address remains correct (catchall@mycompany.com).

Has anyone experienced a similar issue or has any idea how to resolve this? 
I’d appreciate any guidance or suggestions.

Thanks!
