Thunderbird 78.5.0 32-bit for Windows imap email accounts
Good morning! Since yesterday all three of my imap email accounts are marked with a lock in Thunderbird. I can't download my emails in any of the accounts. I can send emails, but they aren't saved in the "sent" folder; I can only save them in a local folder. My provider is 1 und 1. The same email accounts on my Andoid devices - smartphone and tablet - using the Android email app are working fine. My husband has the identical problem - everything works fine on his Android devices, but he can't download his emails using Thunderbird on his Windows computer.
My server settings: imap.1und1.de port 993 SSL/TLS Authentification: password, normal
smtp.1und1.de port 587 STARTTLS Authentification: password, normal
Can someone help? Thank you!
Best regards, Kathryn

The lock icon has always been there, and is normal.
