Every time I open Thunderbird, and every once in a while after I dismiss it, I get a popup window asking me to allow Thunderbird access to my Google Account. The account it is asking for does *not* have an associated Gmail. For extra context: This email account used to be run though Google, but I switched providers since it was a custom email with a custom domain. The email also has an associated Google account for other services. I have tried selecting both deny and allow on the pop-up window. Deny just closes the window, which reopens after some time. Accept causes my email to get a security alert that says Thunderbird now has access, but the window still appears again after some time. I am not sure of how long either of these options last before the window pops up again, and I'm not sure if there is a real difference in timing between the two. I have also tried closing the window without selecting either option, with the same results. I did delete and set up the account again once, to no difference. Also, I'm not seeing anything in the settings of the account that would suggest it belongs to Google, but I am also not the most savvy when it comes to these things. Please help, this has been bugging me for months and I would really like to not have to keep dealing with it.
