In the Alfresco Outlook Client, you might see a message indicating that you can't connect to Share. This is either because your repository is not running, or you have issues with your setup. From the toolbar, check that your sign in details are correct in Configure > Connection and click Check connection. You can also enable debugging in Configure > Extended to get more information on the issue. You will need to provide this log if you need Alfresco Support to resolve your issue.
