Hi there,

we have a problem with our work email. It is operated on Microsoft Office platform. However half of the people in our company uses Thunderbird over MS Outlook. Few days ago our mail clients stopped to work on Thunderbird. I enslose the screenshot. On Outlook its still fine and working. Licence with Microsoft is therefore valid. Ohter mails(my private mail, or my second wokr email) work with the Thundrbird still fine.

Can you please help us, working in Outlook is terrible and making my life hell. We would like to stay on Thunderbird. Thanks a lot and have a nice day, Petr.

Není mi jasný původ té hlášky, protože Thunderbird je free a žádnou licenci snad k chodu nepotřebuje. Na tom screenu taky není zřejmá žádná chyba.
