Hi there, i am having problems trying to send an email from Powerbuilder 2017 R3 using default mail client Mozilla Thunderbird on Windows 10.
Thuderbird is the default mail client, but strangely every time i try to send an email the first time the system doesn't recognize it as the default showing a message box. Then i get a logon failure.....
I've tried even to pass uid and password without success.

Also tried to put this line as suggested inside the pb.ini but that doesn't help either:

[PB]
UseSimpleMAPI=yes

            // Create a mail session
            mSes = create mailSession
                
            // Log on to the session
            if vLS_uid<>'' and not isnull(vLS_uid) then
                mRet = mSes.mailLogon(vLS_uid, vLS_pwd, mailNewSession!)    
                IF mRet <> mailReturnSuccess! THEN
                    mRet = mSes.mailLogon(mailNewSession!)
                end if
            else
                mRet = mSes.mailLogon(mailNewSession!)
            end if

any ideas?
