Hi all

I sync .mpp (Professional 2013) to SharePoint Foundation 2013. Everything is OK when i edit in Tasks list or Open with Project.

I turn on Version history in Site Assets, where located .mpp file to track version of this file. It's also OK.

But when i openning the previous version of .mpp file by click on the name of each version, a message displayed as below:

Sorry, we couldn't sync the tasks llist to SharePoint site. Please make sure:

the SharePoint site is running and is not in read-only mode
you have sufficient permission to sync to this SharePoint site
the tasks list is still available and its name hasn't changed
<<OK>>



I click OK many, many times, and finnally, it open the previous .mpp file i want.

The same situation when i click X to close file. I have to click OK any times untill the file closed.

How can i fix it?

Regards,
