Determine Your Mail Server Address
You will use the mail server address for both incoming mail server and outgoing mail server settings when adding your email account to Mail.

Step 1: Open a web browser on your computer and go to webmail.yourdomain.com (replace yourdomain.com with your actual domain name)
For example, if your email address is bob@xyzhealth.com, you would type in webmail.xyzhealth.com
Do not use a search box (from Google, Bing, Yahoo, etc.) or include http:// or https:// when entering the URL into the browser's address bar.

Google account was initially synced with Mac mail app then suddenly stopped getting new mail from that google account. I deleted the google account from my Mac and tried to sign back on for the past month continuing to get the message 'authentication failed: Failed to authenticate with Google, please try again later.'
Nov 01, 2019 With macOS Catalina, Apple made a change to the layout in the Mail app. The classic layout has been updated and you no longer have that option within your Mail Preferences. However, you can change where you see the previews and whether or not you want to use a column layout.

Step 2: You will automatically be redirected to your mail server.
Your mail server address is the first portion of the URL.
In this example, the mail server address is: mail.enguard.com

Step 3: Please write down your mail server address, you will need it to complete the steps below. This is also a good time to login to webmail with your email address and password to ensure that you have the correct login information.

Step 4: Open Mail

Step 5: Click on the Mailboxes tab to show your folders

Step 6: From the Mail menu (top left), select Preferences

Step 7: Click the Accounts icon, then click the + sign at the bottom left

Step 8: Select Other Mail Account... then click Continue

Step 9: Complete the following fields:

A) Enter your name, this will be the displayed on all outgoing messages (what recipients see)
B) Enter your email address
C) Enter your email password

Click Sign In

Step 10: Enter your mail server address twice, then click Sign In

Step 11: Uncheck Notes, as this feature is not supported, then click Done

Step 12: Description: Give this account a name to identify it (useful if you have multiple email accounts in Apple Mail)

Step 13: Click Mailbox Behaviors
Erase deleted messages: select Never from the drop-down
Close Preferences

Step 14 (Optional): By Default, Mail turns ON Conversation mode. Some people like this view, while some people do not.
To turn it off, from the View menu (top left), select Organize by Conversation to remove the checkmark (repeat this step to turn it back on)

Make sure you check for incompatible apps before you upgrade to macOS Catalina, because it no longer supports 32-bit apps!

Let’s take a look at the full list of 235 incompatible apps that the macOS Catalina installer has been programmed to look for.

Why Are These Apps Incompatible With macOS Catalina?

While many developers have transitioned their software to 64-bit versions over the years, there are still many 32-bit apps out there.

After all, not everyone is able or willing to upgrade to the latest version of any software. There are plenty of people who are happy to stick with the software they purchased years ago.

However, macOS Catalina is the first macOS operating system to drop all support for 32-bit apps, rendering all those apps incompatible.

There is no workaround – they will not work with macOS Catalina, period.

What If My App Is In The macOS Catalina Incompatible List?

If an app you are using is listed above, then it is a 32-bit app that will not work with macOS Catalina.

You have two options at this point :

a) if you want to use macOS Catalina – you will need to uninstall that app, and replace it with a 64-bit alternative

b) if you want to continue using the app – then you should NOT upgrade to macOS Catalina. Just stick to macOS Mojave or earlier, and you will do just fine.

Check Your Other Apps Before Upgrading To Catalina!

It would be wise not to just rely on the list of incompatible apps that macOS Catalina recognises, because it is just a partial list of all the 32-bit apps that are still being used worldwide.

You should identify the other 32-bit apps you need to upgrade or replace, before upgrading to macOS Catalina.

The Full List Of 235 Apps Incompatible With macOS Catalina

Hidden in the macOS Catalina’s installer code is a list of 235 apps that Apple has identified to be incompatible.

Please note that this is not an exhaustive list, and mainly covers popular software that Apple will highlight as incompatible during the upgrade process.
