Having issues with Outlook 2010 64 bits on windows 10, I want to move to Thunderbird, but I have difficulties importing my outlook data file.
I was using Thunderbird V36 or 38 (can't remember), where the import was disabled for Outlook.
Uninstalled, installed Thunderbird 17.0.2 (and disabled the autu update), then runninh outlook 2010, opening the import function from the Tools menu from Thunderbird, and I get the lessage that "Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client."
then
"Impossible to find mail to import"
Can you please help in here ??
Also the main screen I get in Thunderbird is the one below, not showing my ail "inbox" ??
