I have a Microsft Exchange 5.5 on an old server. To cut the story short, we bought a new server and replicated everything on the new server except, the MS Free/Busy Schedule (which I overlooked 🙁 ). Now the MS Schedule+ won’t start due to log-on failure. The exact error message is: Error 1069: The service did not start due to logon failure. I read several knowledge base articles from Microsoft website regarding this topic but none helped. I hope to hear from you guys soon. Thanks in advance and more power.
