MAPI error in latest Outlook 2016 (Office365) ? - Microsoft Community


we use mapi send mail our program.

after latest update outlook 2016 (build 7967.2139), have experienced following problem:

the first mail sent correctly through outlook. mails after that, fail send.

the new mail session created successfully, logon mailsession successful, but

the mailsend fails. (no outlook "allow"-window appear)

reverting previous build of outlook solves problem, not acceptable solution,

as of our customers use automatic update of outlook.

any better solutions?

hi 

i have same problem too.

in case solution call mapi logon before sending first email.
