Particular user in group is not receiving mail

OK I have one group (30 members) and when some users (including me) is sending mail to that group, one particular user is NOT receiving that mail. In Domino log, I can see that all users did receive mail expect her. In message tracking, same thing, she is not listed.

  • she doesn’t have that group in local address book
  • when I go to expand public group (for test) prior sending, she is NOT expanded (she is not listed)
  • adding her to the group again didn’t help
  • creating new group with her only and adding that group to group with issue didn’t help
  • some other users can normally send mail to group and she will receive it

It seams that something stucked in some cache, how to resolve this issues? Thanks.

Subject: Do you have a local group with the same name?

Sorry, forget to mention that - no, I don’t have any group in my personal AB. I know for that problem and I also checked personal AB of other users and they don’t have any group in it.
