Weired Group sending to single email address

Hey, I am new here in this forum and I have a strange problem.

I have a shared mailbox, which is used by a single user.

When we send a mail through this shared mailbox, then it "can" happen, that 2 other users get this mail as BCC.

"Can" means, that it does not happen to every user. When we send to xxx@xxx.xx, then this mail get's redirected to 2 other users.

When I look to the log files within Office 365, then I can see that the email from "xxx@xxx.xx" is forwarded to the group "xxx@xx.xx".

What I see is, that always when the mail get's redirected to a group, then the two other members also get the mail - as BCC.

Does anybody know, why emails get send into a group, which does not exist?

THX

    In Outlook for Mac, you can set the Auto BCC option for a Contact Group in Outlook.

    Does the recipient that triggers the other people to get it, have any local contact groups in their Outlook client and/or any rules? You won't see them from the O365 Admin Centre.

      THX for your tip. - But we use Microsoft (Windows and Outlook for Windows) 

       

      And (what maybe is good to know and I haven't written so far) the mail is getting created by a software an accounting software and is sent to Office 365 by using SMTP connection.

       

      So, it has nothing to do with Outlook in this case.

      THX a lot

        Hey

        Does nobody have any kind of idea to this thing?

  • Hi there,
    No Outlook rules on the specific mailbox?
    Only random emails getting redirected? The emails getting redirected,do they have anything common with each other?

      Hey 

      THX for your answers

      No rules are specified.

      Yes, only random emails getting redirected. 

      The receiving mail addresses have nothing in common, only, that these two are the only random receivers.

      The only hint, I have found is, that Office 365 manage them as group mail.

      Where will this get defined, that it is a group mail. Will this be defined by the program, which sends the mail (like Outlook, or in our case an accounting software) or will this defined by Office 365, when it get's an mail?

      THX
