I read about it, but I am enable to understand it, and I can't understand the reason that why anyone who is in admin mode want to disable this feature.
Can someone enlighten me. What i read is pasted below
Background operations | Select to disable all asynchronous operations (see Asynchronous service) such as workflows and synchronization with Exchange. Emails will not be sent and server-side synchronization for appointments, contacts, and tasks are disabled. Note: Administration mode must be enabled to disable background operations. |
