Hi @Nicky Ferkins ,
Welcome to our forum!
What types of the two email accounts do you configure(POP/IMAP/Exchange)?
If you configure your account as a POP account, based on my experience for changing the mailbox name, it is suggestted that you could go to File>Account settings>Account settings...>Date Files tab>choose your account, and double click>change the name>ok.
If you are configuring IMAP or exchange accounts, it is suggested that you could use MFCMapi tool to modify the mailbox name. Please refer to the following steps:
- Download the MFCMapi tool from its official project page(When you use a 64-bit version of Outlook, you’ll need the file starting with MFCMAPI.x64.exe.);
- Extract the downloaded zip-file and execute mfcmapi.exe;
- Accept the dialog prompts to get to the main window of MFCMAPI;
- choose Session>Logon>select the profile for which you want to change the mailboxs' display names>ok;
- Select the mailbox you want to modify in the upper pane and find the line PR_ DISPLAY_ Name in the lower pane, and double-click it;
- In the “Unicode” field, you can now modify the display name of your mailbox;
- Click OK to return to the main MFCMAPI window, and close MFCMAPI;
- Restart outlook.
In this way, your email name will become the one you just modified.
Hope the above is helpful to you. Please contact us if you have any questions!
