There’s a deadline coming in October 2026 that most GoDaddy email users haven’t heard about yet and honestly, that’s a problem.
Microsoft has officially confirmed that Exchange Web Services (EWS) will be blocked in Exchange Online starting October 1, 2026, with a full, permanent shutdown by April 1, 2027. No exceptions. No extensions.
If your email runs through GoDaddy’s hosted Microsoft 365 environment, this isn’t some distant IT concern. It’s a direct and urgent signal that your current setup is running out of road. Here’s what’s really happening, what’s at stake, and why the smartest thing you can do right now is migrate to a direct Microsoft 365 tenant before October arrives.
What Is EWS and Why Should GoDaddy Users Care?
Exchange Web Services, or EWS, is a legacy API (Application Programming Interface) that Microsoft built roughly 20 years ago. It’s the behind-the-scenes protocol that many email platforms and integrations have used to connect apps to Exchange Online syncing calendars, pulling contacts, reading mailboxes, and handling other routine operations.
Here’s the thing: GoDaddy’s hosted Microsoft 365 environment has historically relied heavily on EWS-based architecture. When you manage Microsoft 365 through GoDaddy as a reseller, your tenant configuration, admin controls, and third-party integrations are tied to GoDaddy’s infrastructure layer. A large portion of that infrastructure depends on EWS to function.
So when Microsoft cuts the cord on EWS, GoDaddy-hosted tenants face a dual problem:
- Third-party apps and integrations connected to your mailbox through EWS will stop working.
- GoDaddy’s own reseller-managed features that depend on EWS will be impacted or break entirely.
- Admin tools and migration workflows that use EWS will no longer function in Exchange Online.
This isn’t a theoretical risk. Microsoft themselves have called out that even their own products Outlook, Teams, and Dynamics 365 needed to be updated to remove EWS dependencies. The API is genuinely going away, and GoDaddy’s managed environment has a larger exposure to this than most people realise.
The Exact EWS Shutdown Timeline You Need to Know
Let’s be precise about the dates, because they matter:
October 1, 2026 — Microsoft begins disabling EWS globally across all Exchange Online tenants. Services and apps that rely on EWS will start failing. This is not a soft deprecation. It’s a hard block.
April 1, 2027 — EWS is fully and permanently disabled in Exchange Online. At this point, there is no re-enablement option. If you haven’t migrated by now, you’re looking at broken email workflows, failed integrations, and potential data access issues.
There is one small grace window worth knowing: organisations that configure an EWS app allow list and set EWS Enabled to True before the end of August 2026 will be temporarily excluded from the automatic October blocking. But that’s a workaround, not a solution. It only buys you a few extra months, and the final April 2027 deadline is absolute.
Realistically? If you’re still on GoDaddy’s managed M365 environment by August 2026, you’re already cutting it very close.
Why GoDaddy's Managed Microsoft 365 Makes This Harder to Navigate
This is where it gets a bit specific to GoDaddy users, and it’s worth understanding clearly.
When Microsoft 365 is sold through GoDaddy as a reseller, your tenant is what’s called “federated” with GoDaddy. That means GoDaddy manages significant portions of your tenant configuration on your behalf. You don’t get full global admin access. You don’t control your own identity layer completely. And many backend operations that GoDaddy runs for you use EWS under the hood.
In a direct Microsoft 365 tenant — one you own and manage yourself, or through a certified Microsoft partner like Star Knowledge — you have full control over your environment. You’re not dependent on a third-party reseller’s backend processes staying functional. When Microsoft releases updates, deprecates APIs, or changes authentication standards, you can respond directly and on your own schedule.
GoDaddy has acknowledged the EWS change, but their reseller-managed setup creates an additional layer of complexity. As EWS gets disabled, the handshake between GoDaddy’s admin systems and your Microsoft 365 tenant becomes unreliable. Calendar sync, contact access, email routeing logic, and third-party app integrations all become vulnerable.
The cleaner, more permanent solution is to defederate from GoDaddy and migrate to a direct Microsoft 365 tenant before the October 2026 deadline.
What Breaks If You Don't Migrate in Time
If you’re thinking, “Maybe I can just wait and see,” here’s a practical look at what’s likely to break for GoDaddy-managed users who don’t act before October 2026:
Email integrations with CRM and business tools — Platforms like Salesforce, HubSpot, and older CRM systems that used EWS to sync contacts and calendar events will lose their connection to your mailbox.
Shared calendar and contact sync — Many organisations use EWS-based sync to keep shared calendars and public folders accessible across teams. This breaks completely when EWS is disabled.
Backup and archiving solutions — Legacy backup tools that used EWS to access Exchange Online mailboxes will stop functioning. This is a compliance risk for businesses that rely on automated email archiving.
Custom scripts and internal automation — If your IT team has built any PowerShell scripts or internal tools that call EWS to pull mailbox data, those scripts become dead code overnight.
GoDaddy’s own admin portal features – Certain account management and provisioning features in GoDaddy’s Microsoft 365 admin portal depend on EWS. As those features degrade, managing your users and licenses through GoDaddy becomes increasingly difficult.
The honest truth is that the full scope of impact varies by business. But the direction is clear: staying on GoDaddy’s managed M365 environment past October 2026 is a risk no business should take on unnecessarily.
What GoDaddy Email Users Should Do Right Now
The good news is that there’s a clear, well-defined path forward. Here’s how to approach it:
Step 1: Audit Your EWS Footprint
Log into your Microsoft 365 admin centre and navigate to Reports, then Usage, then Email Apps. This will show you which applications in your environment are currently making EWS calls. You can also run EWS Usage Reports directly from the Microsoft 365 admin dashboard to identify every dependent service.
If you’re managing dozens of users through GoDaddy, there’s a good chance several connected apps are using EWS without you even knowing it.
Step 2: Identify Migration Priority
List every application and integration that depends on EWS in your environment. Categorise them:
- Microsoft first-party apps (these will be updated by Microsoft automatically)
- Third-party apps (check with your vendor on their Graph API migration status)
- Custom scripts and internal tools (these need to be rewritten to use Microsoft Graph API)
- GoDaddy-managed features (these require migration out of the GoDaddy ecosystem)
Step 3: Plan Your GoDaddy Defederation and M365 Migration
Defederation is the process of removing GoDaddy’s federation from your Microsoft 365 domain and transitioning to a direct tenant you fully own. This is the core migration that resolves your EWS exposure at the infrastructure level.
A proper migration covers:
- Setting up a new direct Microsoft 365 tenant with correct licensing
- Migrating email, contacts, calendars, and OneDrive data with zero data loss
- Reconfiguring DNS and MX records to point to your new tenant
- Reconnecting third-party apps using Microsoft Graph API instead of EWS
- User training and adoption support so your team doesn’t skip a beat
At Star Knowledge, we’ve handled hundreds of GoDaddy to Microsoft 365 migrations across SMBs and mid-sized organisations. Our certified Microsoft 365 consultants have a proven methodology specifically for GoDaddy defederation, and we’ve completed this type of migration for businesses ranging from 20 users to over 500.
Step 4: Don’t Wait Until September
This is genuinely important. The August 2026 window for the EWS allow list is not a safety net you want to depend on. Migration projects of any meaningful scale take planning time, testing cycles, and cutover coordination. Starting in August and trying to complete before October is a recipe for rushed decisions and avoidable mistakes.
If you start a migration conversation now in mid-2026 you have a comfortable runway to plan, test, and go live without any deadline pressure. That’s the kind of migration that goes smoothly.

Why This Is Actually a Good Thing for Your Business
It’s easy to read a headline about a Microsoft deprecation deadline and feel like you’re being forced into something. But honestly, if you’re on GoDaddy’s managed Microsoft 365 today, this is a push towards something you’ll be glad you did.
Direct Microsoft 365 tenants – managed properly – give you capabilities that GoDaddy’s reseller model simply doesn’t offer.
Full admin control. You get complete access to the Microsoft 365 Admin Centre, Azure Active Directory (now called Entra ID), security and compliance centre, and every configuration setting Microsoft offers.
Advanced security features. Conditional Access policies, Microsoft Defender for Business, Privileged Identity Management, and proper multi-factor authentication enforcement are all available and configurable in a direct tenant.
Better licensing flexibility. You choose exactly which Microsoft 365 plans work for your business, without GoDaddy’s bundled and often limited plan structures.
Seamless Microsoft 365 Copilot compatibility. Copilot and AI-powered Microsoft features are built on modern Graph API architecture. A direct tenant ensures you’re positioned to take advantage of these tools as they evolve.
Future-proof infrastructure. Moving to Microsoft Graph API-based integrations now means you’re not chasing the next deprecation deadline. Graph API is Microsoft’s current and long-term standard.
FAQs: EWS Deprecation and GoDaddy Migration
Basic email sending and receiving through Outlook will not stop immediately for most users, as Microsoft has already updated its own Outlook clients to remove EWS dependencies. However, third-party apps and integrations that use EWS to connect to your mailbox will stop functioning on October 1, 2026. If your business relies on CRM sync, calendar integrations, backup tools, or any custom workflows that use EWS, those will break. The risk grows significantly by April 1, 2027, when EWS is fully shut down with no re-enablement option.
GoDaddy has been updating their infrastructure to reduce EWS dependency, but the underlying limitation remains: their reseller-managed model restricts your ability to control how your tenant responds to Microsoft’s changes. Even if GoDaddy makes partial adjustments, the fundamental constraints of a GoDaddy-federated tenant (limited admin control, restricted feature access, dependency on GoDaddy’s backend processes) do not go away. The EWS deadline is an industry-wide change that affects the entire architecture of how GoDaddy has built its managed Microsoft 365 offering.
For small businesses with under 50 users, a properly planned migration typically takes 3 to 5 business days, with most of the actual cutover happening over a weekend to minimise disruption. For mid-sized organisations with 50 to 300 users and more complex environments — multiple domains, SharePoint sites, Teams data, and third-party integrations — the project typically runs 2 to 4 weeks from kickoff to completion. The planning and assessment phase before cutover usually adds another week. Starting now gives you ample time to do this right without rushing.
The Window Is Closing
Here’s what tends to happen with deadlines like this: Most organisations wait until Q3 2026 to start thinking about it seriously. Then every Microsoft partner, IT consultant, and migration specialist gets slammed with requests at the same time. Lead times stretch. Quality suffers. Businesses that could have had a smooth migration end up doing emergency cutover work under pressure.
You don’t need to be in that group.
If your email environment runs through GoDaddy’s managed Microsoft 365, the EWS deprecation is your strongest and most concrete reason to make the move to a direct Microsoft 365 tenant now. The technology is proven. The migration path is clear. And the benefits of a properly managed direct tenant extend well beyond just avoiding this one deadline.
