- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Attempting to acquire or use add-ins from the Office Store within Word, Excel, or other Microsoft 365 applications.
- Observed behavior
- An error message appears stating that add-in access is blocked by an organization, preventing the user from utilizing third-party tools.
Ensure you know whether your Office application is activated using a personal, work, or school account, as conflicting account credentials often trigger this security block.
Sign Out of Work or School Accounts in Office
Remove conflicting organizational accounts from your Office applications to prevent their restrictive policies from affecting your personal setup.
Often, simply being signed into a work or school account alongside your personal account causes Office to apply the strictest organization policies across the board.
Launch any Microsoft Office application, such as Word or Excel, and click on File in the top menu, then select Account.
Under the User Information section, locate any connected work or school accounts and click the Sign out button for each one.
Ensure that the product information displays your personal Microsoft 365 account as the active subscription.
Close the Office application completely, reopen it, and attempt to access the Office Store add-ins again.
Remove Work Credentials from Your Device
Clear cached organizational credentials from your operating system or browser that might automatically re-apply security policies.
Contact Your Microsoft 365 Administrator
Request that your IT administrator adjust the organization's tenant settings to allow add-in acquisitions if you are intentionally using an enterprise account.

Frequently Asked Questions
Why is my personal Office 365 account showing an organization block error?
This usually occurs if you previously logged into a work or school account on the same device. Microsoft Office may cache those credentials and inadvertently apply your organization's restrictive security policies to your personal Office installation.
Can I bypass the administrator block to install Office add-ins?
No. If you are actively using an enterprise, business, or education Microsoft 365 license, only your tenant administrator has the authority to change the policy and allow the installation of Office Store add-ins.
How does a Microsoft 365 admin enable add-in access for users?
Administrators can allow add-in access by logging into the Microsoft 365 Admin Center, navigating to Settings > Org settings > User owned apps and services, and enabling the option that lets users access the Office Store.
