Notify me doesn't work on invitee's machines

Hi,

when I send out invitations and invitees accept my invitation they do not have the option “Notify me” checked eventhough they have alarms enabled in general. On my machine it works perfectly well - the box is checked and the alarm goes off at the right time. This results in invitees being late or missing meetings quite often…

I have refreshed my mail design and created a new location document but it didn’t resolve the issue. Any help is very much appreciated!!

Regards, Lukas
