Two distinct IMAP profiles are downloading from one acount (AOL)

Thunderbird Send and receive email

Running Thunderbird 128.14.0esr (64-bit) via 64 bit Win11 Pro v. 25H2 on a Dell Inspiron 16 plus, Core i7-12700H @ 2.3 GHz, 24 MB cache, 40 Gb RAM, 877 Gb free on a 1.8 Tb Crucial T710 NVMe SSD drive. Integrated Intel Iris Xe graphics using 20 Gb shared RAM.

I have 5 email accounts (AOL = Yahoo, Yahoo, GMail, Verizon = Yahoo & MSN) each with a distinct IMAP server description. I also had my daughter's AOL account in the same TB profile.

On 5/9/2026, I foolishly entered my credentials in an AOL request for verification of her account (to allow TB access). As result, my jawarters@aol.com account and her jmwarters@aol.com account somehow became linked. Her email account in TB now contained only messages which were duplicated in my email account.

I deleted her existing jmwarters@aol.com mailbox and attempted to recreate it in Account Settings. Despite entering distinct IMAP settings (user name = jawarters@aol.com, imap.aol.com, port 993 and user name = jmwarters@aol.com, imap.aol.com, port 993) and having distinct SMTP settings with the user name in the Description, the recreated account again downloaded my emails into her TB account. The same happened when I opened TB on my desktop.

Interestingly, TB for Android v. 18 kept both accounts separate. I attach a copy of the TB Android k9s settings file which shows the same IMAP and SMTP settings as the laptop / desktop TB.

Help solve my self-imposed problem! Jim W

Ok I did not read everything. Sorry but time is short.

Yahoo use cookies to manage multiple oauth accounts and reuses them for multiple accounts (ouch). So you need to change a hidden preference to force Yahoo to use new cookies. That is create a private browser window as it is called in Firefox. (it is in essence the same code as Firefox uses to display a window shared by Thunderbird.)

  1. Use the Config Editor to modify the hidden preference mailnews.oauth.usePrivateBrowser to true and restart Thunderbird
  2. Delete the oauth tokens in the password manager for the troublesome accounts.

See https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo under the tag "Configure a Thunderbird preference to make multiple account work".
