Crash when using "Send to > Mail recipient" on Windows under some circumstances (MAPI interface)
UTF-8 support for MAPISendMail
Problem with S/MIME certificate verification when receiving email from Outlook (issue introduced in version 60.5.1)
Changes to the MAPI interface have caused problems when sending a file from the Windows desktop or a folder via "Sent to > Mail recipient" or via an external application like an office package, for example LibreOffice. To solve this problem, reinstall Thunderbird 60.5.2 from one of these locations:
https://www.thunderbird.net/en-US/thunderbird/all/
http://ftp.mozilla.org/pub/thunderbird/releases/60.5.2/win32/
http://ftp.mozilla.org/pub/thunderbird/releases/60.5.2/win64/ (unsupported 64bit version).
Files with non-ASCII characters in their name also cause a malfunction. Two alternative workarounds exist:
Due to changes in the Mozilla platform profiles stored on Windows network shares addressed via drive letters are now addressed via UNC
