IT Services Alerts - Issues sending email through Google Gmail servers, December 16th

First Posted: Friday, 16th December 2011, 4.50pm

Some College users have reported errors in sending email via the Google Gmail servers.  For example, this would affect people connected to the teaching and research network who are using Outlook to interact with a Gmail account, and trying to send email using their SMTP server.

The temporary resolution is to use the College's SMTP server,, to send email.  As an example the typical settings for Outlook are outlined below.  Note that the IS Services Helpdesk cannot provide support for this functionality in accessing a non-TCD email account.
