The idea

Sharepoint Online - Retiring SPO OTP and moving to Entra B2B...is this as big of a nightmare as it looks? (MC1243549)

Pain point
SharePoint Online is retiring OTP-based external sharing, forcing organizations to adopt Entra B2B guest collaboration which leads to unmanageable guest account proliferation and compliance challenges.
Who has this problem
IT administrators managing external sharing in SharePoint Online
Contradiction (TRIZ)
Need for secure external sharing vs. the complexity and compliance risks of managing numerous Entra B2B guest accounts
Ideal final result
Secure external sharing without the need to create and manage large numbers of guest accounts
Suggested solution
Implement automated guest account lifecycle management with access reviews and expiration policies to control Entra B2, while using secure link sharing with dynamic passwords for non-sensitive data.

So this is likely on me. I'm unsure if this is hitting other people unexpectedly - but MC1243549 just hit us today where Sharepoint Online external sharing with a OTP sent to the recipient email is gone. I have a lot of people messaging me demanding to know what I changed with me going "nothing". Now again, this is likely on me as this was probably floated for a while but it just simply escaped me. From the exterior...MS has now retired SPO OTP and is REQUIRING Entra B2B guest collaboration for sharing a link. My first instinct, are you fucking kidding me? So now every single time someone external is sent a link via "People you choose" sharing - I need to enable auto guest creation and my Entra users list is going to be flooded with potentially thousands of guest accounts with zero indication of how to even manage these? What. The. Fuck. I have guest collaboration turned off unless explicitly created via admins with roles. Am I overreacting? Has this hit any of you as well? I need a drink. Edit: It gets better. I'm also failing to realize that these guest accounts need to satisfy my MFA requirements. Holy fucking shit.

Synthesis verdict
**Pivot**. The idea of building a tool to manage Entra ID guest accounts has a clear problem statement and a large target audience, but it lacks a clear revenue model and faces high risk of obsolescence due to potential further Microsoft policy changes. The emotional intensity of the outcry from enterprise IT administrators and SharePoint power users signals a high-stakes, high-frustration scenario, and a product that acts as a proxy or middleware layer could be immediately adopted. However, the idea is not monetizable as it stands, and the risk of regulatory or platform changes is high.

Strengths

  • - Large target audience: thousands of mid-to-large enterprises using SharePoint Online for external collaboration
  • - High-stakes, high-frustration scenario: enterprise IT administrators and SharePoint power users are desperate for a solution
  • - Clear problem statement: Microsoft's forced deprecation of OTP-based external sharing has created operational chaos

Weaknesses

  • - Lack of clear revenue model: the idea is not monetizable as it stands
  • - High risk of obsolescence: potential further Microsoft policy changes could render any adapted solution obsolete
  • - Complexity: the solution may add complexity without clear, user-friendly management tools

Best angle

The venture should focus on developing a proxy or middleware layer that allows OTP-style sharing via email without creating Entra guest accounts, while maintaining compliance, audit trails, and MFA enforcement.

“A solo or 2-person team can build a v1 solution to manage Entra ID guest accounts in 4-12 weeks by leveraging existing APIs and SDKs.”

The idea is to build a tool or solution to help manage the influx of guest accounts in Entra ID due to the retirement of Sharepoint Online OTP and the requirement to use Entra B2B guest collaboration for sharing links. A solo or 2-person team can potentially build a v1 in 4-12 weeks. The technical complexity lies in integrating with Entra ID and understanding the requirements for guest account creation and management. However, the problem is well-defined, and the requirements are clear. The team can leverage existing APIs and SDKs for Entra ID to build the solution. The key challenges will be in handling the authentication and authorization flows, as well as managing the guest accounts. A simple v1 can be built to automate guest account creation and provide basic management capabilities. The team can also explore existing solutions or templates to accelerate development.

“Any venture addressing the SPO Entra B2B shift faces high risk of obsolescence due to potential further MS policy changes.”

The idea isn't explicitly stated, but interpreting the context, the 'idea' seems to be about navigating or offering a solution to the newly imposed Microsoft (MS) requirement of using Entra B2B for external sharing in SharePoint Online (SPO), which replaces OTP with mandatory guest account creation. **Failure Modes Identified for a Hypothetical Venture Addressing This Issue:** 1. **Regulatory/Platform Risk (Score: 9/10)**: MS could further tighten Entra B2B requirements or alter SPO's sharing model again, rendering any adapted solution obsolete or non-compliant. 2. **Churn Due to Complexity (Score: 8/10)**: If the venture's solution adds complexity (e.g., MFA for guest accounts) without clear, user-friendly management tools, clients may abandon it for perceived simpler (though less secure) workarounds. 3. **No-Budget Customers (Score: 6/10)**: Many affected organizations might not allocate additional budget for managing Entra B2B guest accounts, especially if they view the problem as MS's to solve.

“Enterprises are desperate for a way to restore simple, secure, OTP-style external sharing in SharePoint without being forced into unmanageable Entra B2B guest account sprawl.”

This idea taps into a real, urgent, and widespread pain point among enterprise IT administrators and SharePoint power users who rely on external sharing for clients, vendors, and partners. Microsoft's forced deprecation of OTP-based external sharing in favor of Entra B2B guest accounts has created operational chaos: admins now face uncontrolled guest account proliferation, MFA compliance burdens, and loss of granular control - all without adequate tooling or documentation. The emotional intensity of the outcry ('What. The. Fuck.', 'Holy fucking shit') signals a high-stakes, high-frustration scenario. The target audience is large: thousands of mid-to-large enterprises using SharePoint Online for external collaboration, many of whom explicitly disabled guest collaboration for security or governance reasons. These users have budget - they're enterprise IT teams with procurement power - and they're desperate for a solution that restores simplicity, control, and auditability without forcing them into Entra B2B's bureaucratic overhead. A product that acts as a proxy or middleware layer - allowing OTP-style sharing via email without creating Entra guest accounts, while maintaining compliance, audit trails, and MFA enforcement - would be immediately adopted. Competitors like Citrix ShareFile, Box, or Dropbox Business already offer this; Microsoft's move has created a vacuum. The unmet need isn't just technical - it's psychological: restoring trust and predictability in a platform users relied on. This isn't a niche complaint; it's a systemic disruption affecting daily workflows across finance, legal, healthcare, and manufacturing sectors. The market is ready to pay for relief.

Monetization

3.0

“The idea is not monetizable as it stands, as it is purely a technical and operational complaint without any revenue-generating components.”

This idea lacks a clear revenue model or monetization strategy. The post is a venting session about a technical change in SharePoint Online's external sharing policy, not a business venture. There is no mention of pricing, channels, gross margin, or any concrete unit economics. The focus is solely on the operational and administrative challenges posed by the change, with no indication of how this could be turned into a revenue-generating opportunity. The emotional reaction and technical details do not translate into a viable business model.
