SharePoint 2013: Integration between SharePoint and Exchange can only be disabled on-premises
Accessing the My Tasks feature
If the server is set with all the prerequisites, then the user can access the My Tasks page by navigating to his or her Personal page and then clicking the Task link in the left column.
Issue from a PowerUser
When a user navigates to the SharePoint’s My Task area, that user can find the Sync to Outlook button in the Tasks pane of the ribbon.

After clicking that button, the opt-in dialog box is shown. Select the Sync tasks check box to opt in.

When try to synchronize My Tasks with Outlook 2010 you get the following error:
We weren’t able to start syncing your tasks because one or more prerequisites for connection to Exchange server could not be found. Please contact your Administrator to resolve the issue.

According to some posts
A little search on the internet gave me this blog post: (http://netwovenblogs.com/2013/07/27/sharepoint-2013-outlook-tasks-synchronization-issue/ ) who confirms that I need the following prerequisites:
- You will need to have Exchange 2013 in your environment.
- You will also need to install Exchange 2013 Web Services Managed API 2.0
Strange issue isn’t it? This is also meaning that all the corporates using Office 2007 or Office 2010 couldn’t synchronize any task list anymore.
According to Microsoft TechNet
According to Microsoft TechNet: Before you begin this operation, we have review the following information about prerequisites:
- Task Synchronization requires that user profile synchronization be configured in the farm. For information about configuring user profile synchronization, see Plan user profiles and identities (SharePoint Server 2013), and Manage user profile synchronization in SharePoint Server 2013.
- Task Synchronization requires that the work management service application be configured in the farm. For information about creating the work management service application, see New-SPWorkManagementServiceApplication
- Task Synchronization requires Exchange Server 2013.
- Secure Sockets Layer (SSL) is a requirement for web applications that are deployed in scenarios that support server-to-server authentication and app authentication. This is such a scenario. As a prerequisite for configuring Task Synchronization, the computer that is running SharePoint Server must have SSL configured. For more information, see Create claims-based web applications in SharePoint 2013 and follow the steps for creating an SSL site collection and server certificate.
Even TechNet confirms that we need Exchange Server 2013!
Resolution
After a while of searching we could found that Integration between SharePoint Server and Exchange Server can only be disabled on-premises who will resolve our issue.
To disable it, you turn off the Farm Level Exchange Task Sync feature by going toCentral Administration è Manage farm features. This action deletes the timer job and disables the UI integration, bringing back the legacy sync behavior to Outlook.

How does it work after deactivating the farm feature
Refreshing or accessing the My Tasks page launches the aggregator code, if the last time the aggregator ran was more than five minutes prior. This artificial delay is put in place to preserve performance.
There’s no requirement to refresh the page after inline edits, as inline changes are instantly replicated on the original provider. The five-minute delay doesn’t apply to them.
This value can be changed from on-premises deployments by altering the property on the WMA service application object by using Windows PowerShell:minimumTimeBetweenProviderRefreshes 00:05:00
