Hi, I receive in my Exchange PEC mail (italy electronic certified mail) this mail include in attach the original mail and is .eml. When I receive this mail, the attach is 35 byte and not the real size and is empty.

I full patch my Exchange 2010 sp3, I reboot the server and for 6 hours all work perfectly. Then If I receive another pec, the problem come back. I reboot and for 6 hours I work perfectly.

In addition: the mail already downloaded in my account or any account if it's downloaded when the problem is present are not visible after the restart of my Exchange. And he remain lost. Only the new mail are working after reboot.

I try to disable all tranfert agent but the problem persist. Can you help me? T

Hi,

Does this issue occur to only one user, how about sending the email with same attachment to other users?

Use MFCMAPI tool to check whether the attachment is fine on the user mailbox.

If the attachment still not available when checking via MFCMAPI, I suggest we enable the pipleline tracing log:

Enable Pipeline Tracing
