Hello,

I've noticed that when I create a new Attachment and try to set its ContentId property to a string that contains a comma "," and "@", the created value is getting escaped in an unexpected way:

attachment.ContentId = "a,b@mymail.com";

When I retrieve the value of it again, it's modified to:

"a,b"@mymail.com

How can I prevent the ContentId from being modified?

Thanks in advance and regards,
Greg

The attachment.ContentId is parsed as mail address by default. Since comma ',' is standard separator for mail addresses the value "a,b@mymail.com" is quoted to "a,b"@mymail.com automatically.

To disable this conversion, you have to put whole value to quotes e.g. like this:

attachment.ContentId = '"' + "a,b@mymail.com" + '"';
