Change macOS 15 Email last modified 2024-12-14

The purpose of this page is to describe how to change an existing OlympusNet email account on a macOS device.

To setup a new OlympusNet email account see Setup macOS 15 Email

1. Open the Mail application and select Mail to the right of the Apple logo in the upper left corner of the window, then select Settings.
   
   
   
   
2. The window that opens is titled Accounts and the Account Information tab is selected by default.
   
   
   
   
3. Select the Server Settings tab, then change the settings as needed to match those in the following image.
   Note that Automatically manage connection settings is disabled for both Incoming and Outgoing Mail Servers.
   It’s preferable to leave this setting disabled to reveal the Port settings and leave them revealed.
   
   
   
   Reference Port Settings
   IMAP Incoming - 993
   IMAP Outgoing - 587
   POP Incoming - 995
   POP Outgoing - 587
   
   
4. After changing settings, select the Save button. The account will verify the settings. If there are errors, double check the spelling, retype the password in both the Incoming and Outgoing Mail Server sections. Select Save again.
5. If there were no errors, confirm that the changes were successful by quitting, then restarting Mail.
   1. Quit Mail. Select the Mail icon to the right of the Apple logo, then select Quit Mail at the bottom of the dropdown menu.
      
   2. Reopen Mail, then send an email to the same account and same device you’ve been working on.
6. If there were errors sending email, select the up-and-down facing arrows at the end of the Account: line in the Outgoing Mail Server (SMTP).
   
   
   
   In the window that opens, select Edit SMTP Server List. This window might reveal conflicts with other email accounts. OlympusNet support can help identify those conflicts. Check that your window mirrors the settings shown below.
   
   
   

Incoming and Outgoing Mail Server Conflicts

If multiple email accounts have been set up, multiple IMAP servers might share an SMTP server. If so, it would be helpful to identify which Incoming Mail Server (IMAP) account is associated with which Outgoing SMTP Server (SMTP).


In the Edit SMTP Server List window immediately above,
janedoe IMAP and johndoe IMAP in the In Use By Account column are set in the Description field shown in step 2.
janedoe SMTP and johndoe SMTP in the Description column are set in the Description field shown in the image immediately above.

Use the Connection Doctor to view the status of the IMAP and SMTP server

In the dropdown menus displayed to the right of the Apple logo in the upper left corner of your screen starting with Mail File Edit, select Window, then drop down to Connection Doctor to identify the status of your incoming and outgoing IMAP and SMTP connections.

Archive Significant Email to Local On My Mac Mailboxes

We recommend archiving significant email to your laptop or desktop computer in On My Mac mailboxes so that they are under your control and where you can back them up locally. This is particularly important for IMAP mail because IMAP mail is synchronized between the server and IMAP mailboxes. If mail is deleted from an account on the server, it is deleted from all IMAP mailboxes on all devices.

The following image shows two user-added On My Mac mailboxes, Family Mail and Tax Records.
