We've just started having an issue with Thunderbird continually prompting for Calendar passwords, but not remembering them. IMAP and SMTP seem to be retained ok. Additionally, if we just skip past the prompts (we are using around 5 different calendars), and just go and click the "Enable" button....they open just fine and we don't get any prompts, until we close and re-open Thunderbird. We're running 115.12.1 on Windows 10, 11 and Server 2022 Datacenter. It's not a devastating problem, but a little tedious for some of our users that open and close their Thunderbird a lot during the day. We are running "Smartermail" V8909 from Smarter Tools as our mail server. Thanks in advance!
