If a calendar invitation to email@example.com contains any of these file formats, or has a message size that is > 1 MB, EVA's mailbox will reject the invitation a send a bounce back to the sender. For example, the bounced invitation might say something like: "For your protection, our email server rejects messages that could have been sent by accident. Please make sure you only include a calendar invite (and nothing else) in the message."
Depending on how your email server is configured, you might also receive a more generic bounce message, such as "Your message wasn't delivered due to a permission or security issue. It may have been rejected by a moderator, the address may only accept e-mail from certain senders, or another restriction may be preventing delivery."
In order to remedy this, please ensure that when you invite EVA to a meeting, no additional attachments are included in your invitation. Simply re-send the invitation to firstname.lastname@example.org, without attachments, and your invitation should be accepted normally.
