Microsoft Office 365 for NetDocuments


With the Microsoft Office 365 for NetDocuments, you can create or open Word, Excel, or PowerPoint files and store them in NetDocuments. 

When you want to edit them, use Office Online web apps or the Office mobile apps, and save them directly back to NetDocuments. NetDocuments is a cloud storage provider for Microsoft.


Microsoft Office 365 for business is a subscription method for many of Microsoft's products and services. It is required for this integration. Learn more about Office 365.

How do I create or edit Office files from the NetDocuments web interface?

Editing an Existing Document

Using the right-click menu, users will see Open in > Microsoft Word Online. This will open a new tab or window and prompt the user to login to their Office 365 for Business account. The document will then load automatically for editing. 

  1. Right-click on an Office document (Word, Excel or PowerPoint) stored in NetDocuments.
  2. Select Open > Microsoft [Word] Online.
  3. The document will be opened in the Office Online app directly and be checked out in NetDocuments. The document will open in a separate browser tab. 
  4. A Microsoft login is required when opening the Office apps and typically just the first time if you have your authentication credentials saved or you are on your organization’s network that has already associated your login credentials with a Microsoft subscription. You may need to contact your IT administrators for assistance.
  5. Edits being made are automatically saved. You will notice the “saving” display changed to “saved”. When you are completed, you simply click the Save button and close the browser tab and return to the original NetDocuments interface. The document will be checked in.


Edits are saved automatically in real time as you work on the document. Once you are done editing the document, simply click the Save option to ensure you have all of your changes saved and close the window or tab. The document will be checked in automatically. (The New Version option under the Check-In List does not allow you to save the document as a new version after using the online editor.)

NOTE: When editing an Excel spreadsheet, if you close the window while a cell is still active (the cursor is blinking), then the edits in THAT cell won’t be saved. Before closing a spreadsheet after editing, click into a blank cell to ensure data in all cells is saved.

NOTE: Signed documents cannot be edited using the online editor, but they may be viewed in the Preview pane. 

The Document ID will not be inserted or updated when editing a document with the online editor. However, if you subsequently open and save using the local editor (Word) the Document ID will be automatically inserted into the document if you have that setting enabled in ndOffice.

Creating a New Document

  1. In the NetDocuments web interface, select Add > Blank Document.
  2. Complete the document name.
  3. Select the document format Microsoft Office Online apps > Word, Excel, or PowerPoint.
  4. Choose filing location and complete any required profile attributes and then select OK.
  5. The new document will open in the respective Office app directly and be checked out in NetDocuments. The document will open in a separate browser tab.
  6. As with editing, a Microsoft login is initially required.
  7. The editing process is the same as in Step #5 above under "Editing an existing document."
  8. The next time you open and save the document with the local editor (Word), it will be stamped with the Document ID per your settings in ndOffice.


Co-Editing a Document

Co-editing allows more than one person to edit a document simultaneously. The changes are made and seen in real-time when more than one person is making edits to the document.

How do I co-edit a document with someone else using Office Online?

  1. The first user who opens the document using Office Online will have it checked out under his or her name.
  2. The 2nd or additional users (can be more than 2) will need to have access to the document in NetDocuments.
  3. The 2nd user follows the same steps to edit online by right-clicking on the respective Office document, selecting Open in > then selecting Microsoft [Word] Online.
  4. The fact that the document is checked out by the initial person doesn’t matter for the subsequent people as long as they have rights to edit. 

While in the online editor, users will be able to see the names of other users who are editing it:

Each user's edits are shown in real time in the document as the edits are made:

NOTE: The user who enters the document last will be shown in "Last Modified By" field.

Click "Save and close" to close the document, or just close the browser tab. The document will then be checked in after all users have exited the document. 

This feature is also known by Microsoft as co-authoring—a very useful feature for users on the road or those who need to collaborate and review or edit documents in real-time with staff and others, even those at remote locations.

For example, some potential use cases might be:

  • An attorney is out of the office, but has access to ND and he/she wants to have the secretary make some changes. The attorney can follow along and also make edits if needed at the same time. 
  • An attorney is in the courtroom and wants some real-time editing of a document. The assistant who is back at the office, can be making changes which instantly appear in the document for the attorney in the courtroom.

NOTE: All editors must access the files via the NetDocuments web interface and must have edit rights. Co-editing is not supported with the Office mobile apps - only the Office Online web apps.

NOTE: Co-editing is also available for ShareSpace users.

What editions of Office 365 do I need?

An Office 365 for Business subscription is required to use the online editor to edit Office files that are stored in NetDocuments. Please refer to Microsoft for their Office 365 for Business accounts.

Do I need to sign in with a Microsoft login in order to edit Office files?

A Microsoft login is required when opening the Office apps and typically just the first time if you have your authentication credentials saved or you are on your organization’s network that has already associated your login credentials with a Microsoft subscription. You may need to contact your IT administrators for assistance. 

What are the supported Microsoft Office file formats?

Office Online supports editing for .docx, xlsx, and pptx files only. Any Office 97-2003 files (doc, xls or ppt) cannot be edited with Office Online.  

Are there any file size limits when editing documents with Office Online? 

The following Microsoft file size limits apply when editing files with Office Online: 

  • Excel: 5MB
  • PowerPoint: 300MB
  • Word: (100 million characters in the document XML) For the vast majority of use-cases, this limit is irrelevant. 

Are the documents stored on Microsoft servers while they are being edited? 

There are two classes of customer data that flow through Office Online servers: user metadata and customer document content. User metadata consists of URLs, email addresses, user ID’s, etc. This data lives in memory and travels back and forth between Office Online and NetDocuments through HTTPS. Office Online goes to great lengths to scrub all personally identifying information (PII) from its logs.  This scrubbing process is regularly audited to ensure Office Online is compliant with several different privacy standards such as FedRamp in the USA.

In the case of customer content, Office Online retrieves it from NetDocuments in order to render it for viewing or editing. The information on disk is encrypted, and customer content only lives on Office Online servers during a user editing session and users can reasonably expect that their content will no longer live anywhere on Office Online servers once the content has been saved to back to NetDocuments when the editing session has been closed. The exception to this is caching. 

In order to optimize view performance for PowerPoint Online and Word Online, Office Online stores rendered documents in a local disk cache. This way, if more than one person wants to view a document, Office Online only has to fetch it and render it once. Documents in the cache are indexed using the Document ID and a time stamp. No user information is used to index the file. On every request for a file, if NetDocuments validates the access token, Office Online uses the Document ID returned by NetDocuments to check for the file in the document cache. Because the hash is generated using information unique to the file and not based on any sort of user data, Office Online cannot retrieve information that is specific to a given user. Office Online specifically does not log the cache key when the file is cached so that it is effectively impossible for Office Online to retrieve information associated with a specific host or user without the participation of the host.

Documents live in the cache until they become unpopular. That is, the cache is not time-based but rather is based on available space and usage. Unpopular files may expire out of the cache in only a few days while popular documents may remain in the cache for up to 30 days.
