Outlook classic popping up to login into account

[Liane]

Outlook classic popping up to login into account when I have been using the same settings for years. I use pop.gmail for the server and it won’t connect now. Having the same issue with 2 other computers and the one that uses imap is working.

This just happend to my wife. She is using Office 2016. This is related to 'modern authentication' which older versions of Outlook don't support:

Modern Authentication configuration requirements for transition - Exchange | Microsoft Learn

To get her Outlook to work I had to turn on create an App password.

Here are the instructions for GMail (Telus uses Google to host their email):

Sign in with app passwords - Gmail Help

I use Office 2021 and it uses modern authentication so it's not an issue there.

Same issue with Outlook 2016. 2FA & app password fixed it. Thanks for posting.

I have Office 2021 on 2 computers and one is the older version of office and even the 2 new ones are doing the same thing. I am now wondering if it has something to do with using Outlook classic as it isn't signed in through google as I just tried to use the new Outlook and I would sign in through Google. Which do you use?

Thanks for the help

When I set up the account in Office 2021 it pops up a web page for Google to login where I enter my login credentials.
