Four images on this page are not displaying.

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.
   
   
   
   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 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 you may have set up. OlympusNet support can help identify those conflicts. Check that your window mirrors the settings shown below.
   
   
   

Outgoing Mail Server Conflicts

If multiple email accounts have been set up, some of them might share an SMTP server. If so, it might be helpful to identify which Incoming Mail Server account is associated with which Outgoing SMTP Server.

1. Change the Incoming Mail Server (IMAP) Description as shown in Step 2 from Olympus to janedoe IMAP.
2. Change the Outgoing Mail Server (SMTP) Description as shown in Step 6 from Olympus to janedoe SMTP.
3. Note the changes in the windows we’ve been working with.
4. 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 IMAP and SMTP accounts.

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. This is particularly important for IMAP mail because IMAP mail is synchronized between the server and IMAP mailboxes. If mail is deleted from a particular 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.
