As we wrap up an exciting quarter filled with innovations and announcements, we have some great new features to share with you.

Here is the latest and greatest that landed in production in the month of June 2019.

  • Password protected Anyone sharing links
  • New files experience in Outlook mobile
  • External sharing with AAD B2B (Preview)
  • OneDrive sync client B2B sync across organizations

Password protected Anyone sharing links

Roadmap ID: 27018

OneDrive is the files app for Microsoft 365, and it is a powerful sharing tool, too. Sharing can be managed and customized by broad or granular policies.

In our continuous effort to empower end users to share securely and have full control over their shared content, we are happy to announce that we have now added the ability to set custom passwords while sharing a file or folder with anyone links to their colleagues within or outside their organization. You can share the password separately with your intended recipients and they will be required to enter the password in order to access the shared content. If they accidentally forward or re-share the shared link, anyone without the password will not be able to gain access.

New files experience in Outlook mobile

Roadmap ID: 27015


With this new feature, we have rolled out a new and improved file picking experience to Outlook mobile that lets you quickly and easily attach files you are working with across Microsoft 365. Now, when you attach a file , you will be able to easily navigate and browse though all files and folders across your OneDrive as well as frequently accessed and followed shared libraries. A list of " Recent Files" gives you easy access to the content you have been working on currently and provides a similar Recent experience to what you see when attaching a file in Outlook on your desktop. You also have the option to chose files from the various attachments that have been shared with you over email.

External sharing with B2B integration (Preview)

Roadmap ID: 33415


We are taking necessary steps in enhancing controls over Business-to-Business (B2B) collaboration. Azure AD B2B platform enables external users to exist in your Azure AD directory as “Guests” and can be managed in the way you are already familiar with.

This new feature integrates external sharing in SharePoint and OneDrive with Azure AD B2B. It includes external sharing of files, folders, list items, document libraries and sites. The integration also expands the one-time passcode authentication experience to SharePoint sites and lists when sharing with external recipients who don't already have a work, school or a Microsoft account (MSA).

With the integration turned on, when a user shares an item in SharePoint or OneDrive with an external user, a “Guest” account is immediately created for that external user (if one does not already exist). As a result, any sign-in or conditional access policies in place in your organization will take effect on those external users as well.

Note: This integration is opt-in during preview and so this roll out will not affect you unless you opt in.

OneDrive sync client B2B Sync across organizations

Roadmap ID: 33413

Along with facilitating controls over external sharing between businesses, we are also rolling out capabilities in the OneDrive sync client to let users sync libraries or folders that have been shared from other organizations. Now you can sync content shared not only by peers within your own organization, but also by partners, customers, external contractors, suppliers and third-party vendors outside of your organization that you regularly collaborate with.

This feature works in tandem with the external sharing integration (above feature) and requires recipients to have a “Guest” account in Azure AD to make B2B collaboration possible. Linking a user’s guest account at one organization to a member account at another organization enables single sign-in access to all content they have access to from their own organization and from any other organization that has created a guest account for them.

External sharing with B2B integration

It includes external sharing of files, folders, list items, document libraries and sites. The integration also expands the one-time passcode authentication experience to SharePoint sites and lists when sharing with external recipients who don't already have a work, school or a Microsoft account (MSA).

When you announced Secure Links in October 2017, the sharing for folder and files was possible for non Microsoft accounts, e.g. a Gmail or other private, external accounts. I tested and confirmed this behavior with several accounts.


 A quote from the previous announcement:

Secure links allow external recipients to access files and folders securely without requiring them to create or maintain a Microsoft account.

I try to find a post where Microsoft describes that this feature was limited to work, school or Microsoft accounts after the rollout? Maybe you can help me to find the post or announcement?

Great stuff. Noticed these all lighting up recently. Almost to the point where it's getting harder to think of things OneDrive could use feature wise, which is a good thing! 


P.S. The Uservoice site redesign was nice, but there are so many items that have been completed or announced that are marked as "Thinking about it" etc. that need updated. Basically seems someone lost the job of updating it, and hasn't been taken back up :p




@Tobias Asböck, you are correct, the previous "Secure Links" announcement mentioned that we are bringing One Time Passcode (OTP) experiences to sharing for files and folders. The primary motivation for that change was to not require recipients to create an account in order to be able to collaborate. In addition to the other value that Azure B2B integration brings, this preview keeps that behavior: if you don't already have an account, you authenticate via OTP instead of creating an account (but if you already have an account, you will keep using that account).


@Chris Webb, glad you think so! Certainly more awesome stuff coming! I'll pass the feedback along to our UserVoice owners and tell them to get their act together ;)

@Stephen Rice In B2B (External AzureAD) collaboration I see a lot of situations where the guest users UPN (User Principal Name) is not equal the users Email. This causes a lot of frustration/problems with OneDrive/Sharepoint sharing. Is it any ongoing work to do anything around this? In my opinion the B2B/Sharpoint should be able to do an internal/automatic mapping both ways between UPN <---> Email (Including email aliases)

Nice to see these features being rolled out. Especially cool is the feature with the password-protected links. At the moment it will only work for everyone. Is it planned to make it also available for specific-people-links? If yes, is there already a date here? Also this was announced at the same time as the expiry date for links which is already available in targeted tenants. Are there any plans to release this in the next month? Thanks in advance and keep up with your awesome features and roundups!

I don’t see the Point for passwords on specific people. They get direct access to files and their password is their account authentication. I could possibly see a password option on org wide links but not specific people. 


@Rune Myrhaug, Can you share more about the cases where you see issues here? We've generally tried to architect this system so these kinds of cases still work but a specific example where you are running into trouble would be helpful in diagnosing.


@Niklas Murr@Chris Webb, password protected links are only available for Anyone links today though we certainly may extend it to other link types in the future. Password protecting specific people links is a little odd (it kind of works like a second factor of authentication) but really Chris is correct that it is mostly redundant. Where password protected links are most helpful is in ensuring that links that are broadly accessible still have an additional layer of control that prevents accidental resharing (if you accidentally post that anyone link on a public website, it won't actually give anyone access).


As for expiration, we're working very hard on the expiring external access feature (it actually happens on a per site level, not a per link level). You should hear more about that soon. Thanks!

@Stephen Rice @Chris Webb Sure it seems odd at first. 

Imagine that we as a company release a file with sensitive data to an external partner. We cannot control what security measures they have taken. If the partner with the release has an authorization to his mailbox as a holiday replacement, this third factor comes to bear. Furthermore the functionalities like block download as well as the link expiration date would make a lot more sense for external sharing with specific people.
Like many companies, we have deactivated the anyone link for security reasons and replaced our cryptshare (solely used for external sharing) with OneDrive. It would be great to see more security features for external sharing with OneDrive.


Is there a way to enforce password requirement if Anyone with a link is selected?


Hi @Niklas Murr, I can see some cases where that would be useful, yeah. In the meantime, with the Azure B2B preview, you'll also be able to require MFA for guest users as well which is certainly a nice security boon too. We'll keep passwords in mind for future though for sure!


Hi @Daniel Schmidt, there is no way to do that today but I was definitely curious to see if this is something people would ask for :) In the meantime, definitely head over to and submit this request! That will help us gauge interest & prioritize the work on our side. Thanks!

Being able to share a file externally and use MFA for added security is certainly needed. 


As OTP does not help.if the recipients email has been compromised.


Even if it came down to the end user sharing putting in a phone number of the recipient as well as the email address or have it captured from the users contacts. A bit cumbersome but better than nothing at all. 


@Stephen Rice regards to the answer back to me on my question around problems with sharing files/documents with users in external AzureAD (B2B) tenants that have UPN not equal Email. Yes, I can give you more information on this, but would like to do that in private communication. Please give me information on where I can send this information.


Br. Rune Myrhaug


@Philip Worrell, thanks for the additional feedback! Azure B2B integration is absolutely going to help with many of these types of cases.


@Rune Myrhaug, go ahead and shoot me a private message here on Tech Community and we can troubleshoot. Thanks!

When will you guys be launching the option to Automatically mount the Shared with me as well as the SharePoint sites that users already added to sync with their OneDrive??


Hi @ColachoMendoza,


We don't have anything to share on automatically mounting Shared With Me but definitely head over to and submit this as an idea! That will help us prioritize this ask alongside the other work the team is doing. Team site automount (available via admin GPO) is currently deploying so if you don't have it yet, you should see it soon. Thanks!

I found some articles saying this is already rolling out:


There's even instructions for this legitimately but no news on when this will finish rolling out for EDU, GOV or Non Profit tenants:

looks like someone already posted an idea about the Shared with me.. let me know if this would do or else I could post one directly.
