We have an internal process that generates emails and one of the recipients is the email address of a Teams channel we have. We've noticed sometimes the subject line of the email is displayed in the channel feed and sometimes not. Nothing is changing in terms of the generation of these emails and we have real people also on the "To" lines of these exact emails and they see the subject lines in their Outlook. Does anyone know why sometimes Teams ignores the subject line? I also notice that when the email posts properly it has the mail icon next to it and when it doesn't the icon is instead a "B" inside a hexagon. It also doesn't list the other people in the To line. See the examples in the attached image... We'd really like to get the subject line showing reliably.
