We changed the domain administrator’s password yesterday as well as the LCService account. I have reset the services to run under the new passwords. The issue I’m having is after the client connects to LCS they have an error saying “Microsoft Office Outlook integration error. Cannot obtain Calendar data from Microsoft Office Outlook. Communicator will attempt to obtain Calendar data again after 15 minutes.” Do you have any ideas why this is or have you ran into this issue before? I have tried repairing Outook. I also changed Microsoft Office Communicator to use Nothing then close it out then reopen it and set it to use Microsoft Office Outlook.
