Acrobat and Reader let you open and save files to online file management services such as Adobe.com, Microsoft Office 365, and Microsoft SharePoint. You can access PDF files hosted on these online services either through their web interface or directly in Adobe Acrobat or Adobe Reader.
Your SharePoint administrator must configure the SharePoint server to enable editing of PDF documents. See this TechNote for details.
To access or save to Office 365 or SharePoint resources, choose New Account from the Open/Save To An Online Account menu.
You can specify the URL using the following options:
(Windows) URL of the repository; for example, http://mysharepointserver/mysite/mydoclib
(Windows) Complete UNC path; for example, \\mysharepointserver\mysite\mydoclib
Mapped network drives
The safest way to work on a PDF file that resides on an Office 365 or SharePoint Server is to check out the file. Other users cannot edit the file while you're working on it.
To check out a PDF file, do one of the following:
(Windows) Using Internet Explorer, navigate to the PDF file on the Office 365 or SharePoint portal. Click the document or choose Edit Document from the file pop-up menu.
In Acrobat or Reader, choose File > Open, choose New Account from the Open An Online Account menu. Then select either Office 365 or SharePoint, and specify the URL or complete UNC path of the PDF file.
If you are required to sign in to the SharePoint server, enter your user name and password when prompted.
You cannot edit a document offline.
When you complete your edits, you can check the file into the Office 365 or SharePoint server. Other users can see the changes. If versioning is enabled, Office 365 or SharePoint also manages version history for the file.
