Gmail Redirect Notices

[Matthew_Winrich]

Good Morning All,  has anyone else noticed that we now get sent to a redirect notice page sometimes when clicking links in Gmail.  I haven't pinned down what exactly is the criteria to get the notice but I have heard of it happening mostly with the links in Google Classroom announcement emails.  Does anyone know what the criteria are to get the redirect notice and if we as admins have any control over it?

That's news to me, @Matthew_Winrich .

Perhaps you can post some screenshots, masked if necessary, so we can see what you mean.

Sure thing.  Here is a screen shot of the notice.  This was generated by clicking on the "See Details" button of a Google Classroom new assignment notification email.

Ok, the actual link looks like this, before clicking.

https://accounts.google.com/AccountChooser?continue=https://classroom.google.com/c/SomeUniqueCodeHer...

And when the test student clicks it, it goes straight to the assignment, no redirect.

Now, this may not be relevant, but in my URL Blocking list I have this.

accounts.google.com/AccountChooser

And in my exempt list I have this, referring to Classroom.

accounts.google.com/AccountChooser?continue=https://classroom.google.com*

That does help fix another problem I found will investigating this issue.  I ran into the classroom links being blocked for student while trying to figure this redirect thing out, this gave me the answer on how to unblock them.  Unfortunately it doesn't seem to explain the redirect notice.  I had another teacher reach out to me today and she is getting the notices for a variety of sites, not just classroom.  Yet when I try to replicate these redirect pages on my test account they don't appear.  Based on what I am seeing the when/why these redirect notices show up is tied to the user accounts.  That being said I would kind of like to know what Google is looking at when deciding weather or not to show the notice.

I would imagine that external/non-Google sites would be more common with redirect warnings, also perhaps with sites where Google knows the content of the destination site may be sensitive.
