Hi,
As mentioned by Leon, this forum is for developer issues about Exchange. For non-developer questions regarding Exchange, the previous TechNet forums have been migrated to a new home on Microsoft
Q&A. We have created a copy of it on Microsoft Q&A Platform:
[Migrated from MSDN Exchange Dev] Some emails never arrive at my Exchange Server email account.
Kindly register the Microsoft Q&A Platform and continue the discussion out there with us.
Regards,
Yuki Sun
