Problem setting up Outlook 2011/2016 with Google-apps email I have an email address managed Google Apps (it uses the imap.googlemail.com and smtp.googlemail.com servers, but the part after the @ is not gmail but the domain of my university). I use exactly the same settings in Thunderbird and Postbox (see here), but couldn't manage to make it work with Outlook 2011 nor 2016.

I get this error:



Any ideas?
You need to add your password in the corresponding field for this options to appear.

Use your email address (complete with the @domain.tld) in the "User name" text field.


Check "Override default port", and "Use SSL to connect" on both servers.
On IMAP use port 993
On SMTP use port 465


Click "Add account".

Select your newly created account and click on More options... under "Outgoing server"



Select "Use Incoming Server Info" for authentication.

If the same settings are working on other clients, it may be the that there is no TLS setting on Outlook. Sometimes it requires a little fiddling to find the right security protocol / port combination, but the above worked for me on my university issued email, which is hosted with Google Apps.

Also, triple check your email address, as the error shown implies an authentication problem and I've banged my head on the keyboard trying to figure out what was wrong many many times, only to discover a typo was the culprit.

This are the recommended settings for any IMAP client from Google, which differ from what you described (on the servers).


  
  Incoming Mail (IMAP) Server - Requires SSL
  
  
  imap.gmail.com
  Port: 993
  Requires SSL:Yes
  
  Outgoing Mail (SMTP) Server - Requires TLS
  
  
  smtp.gmail.com
  Port: 465 or 587
  Requires SSL: Yes
  Requires authentication: Yes
  Use same settings as incoming mail server
  
  Full Name or Display Name: [your name]
  Account Name or User Name: your full Gmail address (username@gmail.com). Google Apps users, please enter
  username@your_domain.com
  Email address: your full Gmail address (username@gmail.com) Google Apps users, please enter username@your_domain.com
  Password: your Gmail password
  
  
  If your client does not support SMTP authentication, you won't be able
  to send mail through your client using your Gmail address.
  
  Also, if you're having trouble sending mail but you've confirmed that
  encryption is active for SMTP in your mail client, try to configure
  your SMTP server on a different port: 465 or 587.


Just to get a final look at a generic configuration:



Note that it does not work, as the credentials and domain are fake (yellow dot to the left of the account). Also, the "Override default port" under "Incoming server" is deselected, as 993 is the default port for SSL, so you can safely ignore my recommendation on that matter and just click the SSL checkbox
