Hi Mohit,

The "Sync to Outlook" button is a new feature in SharePoint 2013 and is different from the "Connect to Outlook" button in SharePoint 2010, and this feature also needs the Exchange Server 2013 installed in your environment, you can read the following article for details.

You can get the "Connect to Outlook" button back (like SP2010) by disabling the "Exchange Task Sync feature" from CA without installing Exchange 2013, the following is extracted from the white paper.

"How to disable SharePoint Server and Exchange Server integration.

To disable it, you turn off the Farm Level Exchange Task Sync feature by going to Central Administration -> Manage farm features. This action deletes the timer job and disables the UI integration, bringing back the legacy sync behavior to Outlook. "

Thanks

Thanks Daniel, I disabled "Farm Level Exchange Task Sync" feature .. and sync to outlook is gone and connect to outlook start appear..which is working fine..Thanks a lot..

Dear MohitJain,

I do the same as Daniel told about disabling the feature.

The Sync to Outlook button is disabled but Connect to Outlook button didn't show up. 

Is there anything that I have done is missing?

Thx.

We have Exchange 2013 servers configured as hybrid servers.  We have no mailboxes on those servers as they are mainly used only to onboard/off-board accounts.  With that being said, our on premise Exchange is 2010 Exchange.

If I read this correctly the base Exchange on premise must be Exchange 2013 for the Task Sync to occur?  If so, then it would be best for us to disable this option since we do not plan on being of off 2010 in the near future to stop this warning message.
