I have a Windows 2000 Small buiness server which had to have the operating system reinstalled. Then company that did this changed the domain name and the server name. Most of my e-mail works fine, but I am having big problems with tasks that have been created before the change and now when a task has been updated and saved the e-mail that is sent to the creator of the task gets bounced back with the error # 5.1.0. I am assuming that the old task points to the old address that has the old domain name. My question is how can I fix old task to point to the new addresses? Thanks for your help Andy
