Summons - a meeting arrives as an email with an attachment

If you are working with an Exchange 2003 server that performs Relay

Using the SMTP Connector to the mail servers of 012 summonses may arrive

Sometimes as an email with an attachment.

There is no known problem with mail servers of other providers.

012 explain why:

From testing and past experience, this is an incompatibility of the mail server in the corporate network.
(usually on an EXCHANGE server that has not undergone a proper update to comply with RFC 2183).
There is no connection between the subpoena problems and the mailbox through which they are sent, but only in compatibility between the CLIENT -
Outlook for example, and the corporate mail server through which they are sent and the other boxes.
