Exchange ghost inbox rule

Hi we have a problem with inbox rules. A user has an inbox rule with priority 1 which forward the e-mail to his colleagues and then stops processing more rules. But when I look in the message tracking log I can see that after the first rule there is also another rule porcessed which forwards the message to some other colleagues. It is a rule which the user has probably created in the past but we cannot find it anywhere.

There is no server transport rules.

If I list the rules' identities of the user I can see the number in the sourcecontext column (15103039195456733186) but I cannot find anywhere a rule with ID 2027470854316621826. Not for any of our users.

Does anybody sees something like that before?

Thanks.
Petr

    Do you see the hidden rule via powershell for that malbox?
    Get-InboxRule -Mailbox Joe@Company portal .com -IncludeHidden

    https://learn.microsoft.com/en-us/powershell/module/exchange/get-inboxrule?view=exchange-ps

    You can also Check with MFCMAPI for that user:

    Another option is to back up the Outlook rules then run:

    Outlook.exe /cleanrules   
    

    and then re-add the needed rules via Outlook

    Hello,

    sorry for not answering. We already solved the issue. The rule was activated by the OOO function. There is separate rules database in the OOO window which we did not know about at all :-)
