'Dear Sir/Madam, I have recently a problem in the number of emails which can be added on my Thinderbird. I did not have this problem before and I could add up even more that 100 emails on my thunderbird. But now I receive a message stating that "'''You’re signed in to the maximum number of accounts. To use another account, sign out of all Google Accounts on this device'''". Could you please kindly help me how I can add more email on my thunderbird? Kinds
