Issues in Apple Mail/ Mail App after Yosemite Upgradation

The issues in Yosemite's emails after upgrading, is just not limited to Outlook For Mac. Instead, Apple Mail users have also been through some issues when it comes to emailing. Some of the common scenarios are:

1. Apple Yosemite Mail Crashes Frequently

This is the most common issue experienced by Apple Mail users after upgrading from Mac Yosemite to El Capitan. Within a few seconds after the Mail is launched, it crashes.

The reason for the above issues can be overloading in Apple Mail due to multiple active accounts. Whenever the accounts are synchronized together, Apple Mail can get overloaded and can ultimately crash.

This can be prevented with the help of below mentioned procedure:

  • In order to prevent Apple Mail to download mails of all accounts altogether, turn off the Wi-Fi connection, before launching Apple Mail.
  • Launch Apple Mail and select Mail option.
  • Now select Preferences option and select Accounts tab.
  • In the Accounts window, click on each account and uncheck the option Enable This Account. Doing this will disable all the mail accounts.
  • Now close Apple Mail.
  • Launch Apple mail and turn on the Wi-Fi connection.
  • Now one by one enable each account by enabling the Enable This Account option.

Note: Do not enable all the accounts at once. Invest plenty of time for each account and only enable the next account when you no longer see the Checking For Mail… option at bottom left side.

Once the above procedure is successfully performed, the crashing problem will stop.

2. Problem in Sending Mails

After upgrading to El Capitan, at times, users have complain that they can receive the emails in Apple Mail but are not able to send the mails successfully.

Resolution: The first thing that needs to be done is to verify that the email client has been configured properly. The user needs to use either SMTP SSL or SMTP Non-SSL settings for configuring.

SMTP SSL Settings:
Incoming Server:
Outgoing Server:
Username: full email address
Password: email account password
Incoming Port: POP3 995 or IMAP 993
Outgoing Mail Server (SMTP) Port: 465
SMTP Authentication Required
Secure Authentication or SPA needs to be turned off

SMTP Non-SSL Settings:
Incoming Server:
Outgoing Server:
Username: full email address
Password: email account password
Incoming Port: POP3 110 or IMAP 143
Outgoing Mail Server (SMTP) Port: 587
SMTP Authentication Required
Secure Authentication or SPA needs to be turned off

Once the configuration settings are checked, proceed with the following procedure:

  • Open Mail and select the Preferences option from the menu.
  • In the Preferences window, select Accounts option.
  • Select the account from which the email is not being sent.
  • In the Account Information pane, make sure that the Outgoing Mail Server is not set to None. In case it is set to None, select your server in the pop-up menu.

Doing this, will enable you to send and receive emails in your Apple Mail account successfully.
