We recently rebooted our exchange 2003 exchange server and when we did many people in the company got a email like this. Some were sent up to a month ago. Is there a problem? Did the people who were the recipients of these emails receive them? I don't want to have to tell everyone they need to contact the recipients of those emails. There are too many of them. Please help:
