Instead of selectively checking in documents, you can also check in all of the documents that you have checked out at one time. However, please note that this action may take some time depending on the number of checked out documents that you have in the Library. Any document that you currently have checked out will be checked in to the server when you perform this action.

To check in all documents:

1. Make sure you are working online.
    
2. On the Document menu, choose  Check in All.
