16 hours ago Attachments exist in GMAIL web interface but not in recent emails on Outlook for Mac. As apparent from the above comments, users facing this issue are unable to view their attachments at all via the Outlook app for Mac. There’s also no form of indication. However, they can still be viewed via the Gmail web interface.

I find this App very useful! Only wish the settings had more options! I personally find having 'Mail for Gmail' very convenient and useful, especially since I can have it open at all times while I'm on the computer working, and during the times I am on the Internet I don't have to stop, open a new tab, and login threw the website.

Yesterday I helped a friend who had a problem where her outgoing email account (SMTP server) for a Gmail based email account kept appearing 'Offline' right after she set it up. Even adding the SMTP server manually in Mail didn't help.

You shouldn’t need to do any of the custom SMTP setup within Mail to get a Gmail based email account working in macOS. Now Gmail accounts should be setup just through 'Internet Accounts' in the System Preferences, and the SMTP will be setup automatically. Ebook converter mac app.

Removing the account and setting it up again should take care of the issue.

If your SMTP server / Outgoing Mail Account constantly appears 'Offline', here's how to fix it:

Close Mail if it's open now.
Click the Apple menu (upper left corner of your screen) > System Preferences > Internet Accounts.
Select the account with the broken outgoing mail server, and then click the minus sign at the bottom.
Reboot your Mac.
Click the Apple menu > System Preferences > Internet Accounts.
Click Google, and sign into your Gmail based account again.

Update February 26, 2018:

If you're email is still not working after this, in Mail open the Mail menu > Preferences > Accounts and select your Gmail account. Ensure that the little checkbox for Enable this account is checked.

If your Mac is connected to the Internet but suddenly starts asking for your password, you should generally try again later, and if necessary work with your email provider to resolve. If you're using Apple's iCloud Mail, learn how to resolve issues with iCloud Mail.

Why is Mail asking for your password?

Mail asks for your password when it is connecting to your email provider, but can't connect to your email account because your email provider isn't accepting your email password.

Your email provider may reject your password for several reasons, including:

You're not using your current email password. If you updated the password on another device, make sure that you're using the same password on your Mac.
Your email provider needs you to update or reset your password for security reasons. For example, if you're using Google’s two-step verification, your Gmail account in Mail requires the appropriate app-specific password.
Your email provider deactivated or suspended your account. Contact your email provider for help.

Check your password in Internet Accounts preferences

Depending on the type of email account you're using, you might be able to correct the password as follows:

Quit Mail. If it doesn't quit, you can force it to quit.
Choose Apple menu  > System Preferences, then click Internet Accounts.
Select your mail account in the sidebar.
If you see a password field for your account, delete the password and type the correct password.
Close System Preferences, then open Mail and try using your account again.

If Mail still asks for your password, the password is probably incorrect. Your email provider can help you verify your email settings and make sure that you're using the correct password.

Test using webmail

Many email providers offer webmail, which is a way to use email with a web browser such as Safari, instead of with an email app such as Mail. For example, if you're using an iCloud Mail account, you can use iCloud.com to send and receive email.

Because the password that you use with Mail is usually the same password that you use with webmail, try signing in to webmail with that password. If it doesn't work there either, your password is probably incorrect. Your email provider can help you verify your email settings and make sure that you're using the correct password for the Mail app.

Remove your account, then add it back

If no other solutions work, try setting up your email account again. To do that, first remove your email account, then add the account back.
