One Drive File Stream

There are all kinds of data that is handled and stored by Microsoft 365 (formerly Office 365) products from emails, files & documents, SharePoint lists and sites’ content, MS Teams’ conversations and MS Stream’s videos.

So, where / how do these Microsoft 365 (formerly Office 365) products (Outlook-Exchange Online / SharePoint Online / OneDrive for Business (OD4B) / Teams / Stream / Yammer…) Store Files/Data?

Microsoft 365 (formerly Office 365) safely encrypts and stores customers’ data on Azure Storage in one of Microsoft’s data centers in the region that is mentioned in the tenant’s organization profile (in the admin center, a global admin account is needed for this): Admin Center > Settings > Organization Profile > Data Location > View Details, although a copy of some of it is stored locally on the customer’s device. Below a table that summarizes how each O365 product actually handles the storage of each content/data type:

You can play most audio and video files, including mp4, Apple and QuickTime movie files directly from the OneDrive website. Supported audio and video formats in OneDrive. The following audio/video files can be played directly from your OneDrive in most browsers: 3G2, 3GP, ASF, BMP, M2TS, M4V, MOV, MP3, MP4, MP4V, MTS, TS, WMV. The video file will now begin to download. Step 3: Go to Chrome’s Downloads tab and pause the download. Then copy the download link from the Right-Click/ Context Menu. Step 4: Now open VLC and in the file menu, choose “Open Network Stream.” Paste the download link into the URL box and hit play. Google Drive File Stream will open, and you should see the following window. In Google Drive File Stream, click on the right-pointing arrow until you see Open Explorer. (Each window to which you navigate provides a feature of Google Drive File Stream.).

Microsoft 365 Products’ Data storage in Detail:


When you set up your email account in Outlook, a local copy of your information (profile settings + mailbox content & metadata) is stored on your computer. This is to allow you access to your previously downloaded or synchronized email messages, calendar information, contacts, and tasks without an internet connection.

Certain types of accounts, such as POP accounts, store their information in Outlook Data Files (.pst files). Outlook 365 accounts, Exchange accounts, IMAP accounts, and accounts store their information in Offline Outlook Data Files (.ost files), Although you still export your data in this case in .pst files for backup or to import it elsewhere (.ost files data can’t be imported or backed up).

There is another type of files .nst (Outlook Group Storage File), used only when you access a group in your outlook, and just like .ost files, .nst files are constantly being synchronized with the mail server, so there is no need to back them up or import them (if you are setting up a new installation of outlook on a new computer). For more details, visit Microsoft’s own documentation.

On the server side however, Exchange Online (the mail server) uses an Exchange Database file (an .edb file) to store all data related to your accounts.

SharePoint Online

SharePoint Online uses multiple SQL databases (called content databases), to store customers’ data (sites content, list item, files and document, in addition to metadata) on Azure Storage in a safe and encrypted manner.

When you upload a file to SharePoint, that file gets disassembled and stored across different tables of the content databases mentioned earlier in an application code.


So basically, the program stores data as an abstracted code that is encrypted and broken down to be stored in various storage devices in the data center. All that data is mirrored / backed up in at least one other data center (mostly within the same region) to ensure the high availability / recover-ability in case of a disaster or in case you request its restoration after an accidental deletion of content on your part (but before the recovery period ends, more on that subject here).

OneDrive for Business

OD4B uses SharePoint Online behind the scenes on the server side to handle file and document storage. So, your data exists on SharePoint content databases as described in the previous paragraph, in addition to the OneDrive Folder on your local machine that contains the synced files.

MS Stream

Microsoft built an entirely new Azure Service to handle MS Stream functionality & data. That service stores the videos and their metadata using a variety of Azure SQL tables, Blobs and Azure media services.


Yammer’s connected groups use SharePoint to store the shared files and documents (since July 2019), meaning that they end up in SharePoint’s content databases as described in the SharePoint Online paragraph above.

As of the writing of this article, Yammer continues to use its own cloud services for storing the rest of its data (other than files shared in connected groups as stated earlier).

MS Teams

I left MS Teams for last, since the way it handles the storage of customers’ data is a bit more complicated than the previous ones, because as you may have noticed, Teams is heavily integrated with many of the other products.

So, there are some items (such as chat conversations and images shared during those conversations…) where MS Teams uses specific Azure blob, SQL tables, and queue storage (collectively known as the MS Teams Substrate).

As for the other items: the files are stored in SharePoint and OD4B, and meeting recordings are stored in MS Stream, all of which in turn use Azure storage. To support eDiscovery, copies of conversations and chat messages are copied to Exchange Online, which also uses Azure storage.

The table below provides a full picture of how the storage of each item is handled (credits to this article for this table):

Security & Data Residency in Microsoft 365

Any tech giant delivering public cloud services on a large scale (and Microsoft is right there at the top with Amazon), can make investments in security on behalf of many customers, and as a result, can provide higher levels of service & security than any one customer could ever do on their own.

As to large multinational corporations, It is impossible for Microsoft 365 to guarantee data residency in every country that your corporation operates in (at least not at the moment of writing this article). So, unless data residency in your case is mandatory due to regulation or to a binding client contract, the case can be made that your data would actually be better managed and more secure on Microsoft 365 (formerly Office 365) and on Microsoft’s cloud storage.

Video language

Select the language spoken in the video. This will enable a closed caption file for supported languages to be automatically generated. In addition, people with the correct license will be able to discover your video based on the text in this transcript.

For more information see:


Automatic thumbnails are generated for the video after it's uploaded. When the frames from the video are generated, choose one to represent your video or upload your own custom image.


In the permissions section, you can control who can see your video, who can own and edit it, and which groups and channels it’s displayed in.

See this article for more in-depth information on video permissions.

Allow everyone in your company to view this video

When checked everyone in your organization can see the video and is able to add it to their groups and channels. This, in effect, makes your video available for viewing companywide. To be able to add a video to a companywide channel, this check box must be checked.

When not checked, your video will only be viewable by those people and groups you've made viewers.

Shared with

Use the Shared with drop down to narrow your search scope and pick who you want to share your video with.

  • Groups - search scope to add your video to a group that you can contribute to.

  • Channels - search scope to add your video to a channel directly, including companywide channels.

  • People - search scope to grant permission to individual people, AD Security Groups, and/or Microsoft 365 Groups that you don't have contribute rights to.

Any person or group added will automatically be granted view permission to your video. If you want any of these Viewers to also be able to update your video, check the box next to their entry in the Owner column to upgrade their permission.

Google Drive

The Display check box shows up for groups where you are a contributor. This controls if the video shows up in the group's pages in Stream. If it's not checked it means that the group has access if you send them a link or they found the video in search, but it won't show up on their group's pages directly.

For more information about permissions, see Video permissions.


In the Options section, you can control various settings for the video.

If you don't want users to be able to add comments directly on the video player page, set Comments to Off.


Closed captions are a text version, in the original language, of what's spoken in the video. When a video has a caption set, viewers can click the CC button on the player while watching a video to show the captions under the video.

If you've selected a supported Video language in the Details pane for the video, then the Autogenerate a caption file check box will be checked. This means a caption file will be automatically generated. In addition, people with the correct license will be able to discover your video based on the text in this transcript or your own uploaded closed caption file.

If you deselect the box, Autogenerate a caption file, then you can upload your own closed caption file in the WebVTT format.
