Hi anne-miller, please add the affected email address to the private notes section of your community profile and post back to let me know it's done.
Don't put it there, it is available for all to see, so go back and remove it. Put it in the Private notes section towards the bottom here:
Thanks Anne, I've run a repair on your mailbox for you. It seems to have recovered quite a few emails. Please check and let me know how you get on.
