How to Open an Excel File Protected by a Former Work Account
Question details
The user is unable to open an Excel workbook because it is protected by a former Microsoft 365 work account that they no longer have access to.

- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Attempting to open an encrypted or rights-managed Excel file after losing access to the originating work account.
- Observed behavior
- Excel denies access, stating the current account does not have permission to open the file.
Verify which Microsoft account you are currently logged into and locate any contact information you might have for your former organization's IT department or the original file creator.
Contact the Former Organization's Administrator
Since the file uses Microsoft Rights Management or enterprise encryption, it can only be decrypted by an administrator of the organization that applied the protection.
Microsoft 365 Personal support cannot remove enterprise-level protection or decrypt files. The encryption is tied strictly to the organization's tenant and policies.
Reach out to the IT helpdesk or system administrator of your former workplace using a phone call or external email.
Explain that you need access to a specific file previously tied to your former work account. Provide them with the file name and context.
If company policy allows, ask the administrator to open the file using their overarching permissions, remove the password or rights management, and send you a standard, unprotected Excel file.

Ask the Original Content Owner to Remove Protection
If you did not create the file yourself, the person who originally created and protected it can modify the access permissions.

Frequently Asked Questions
Can Microsoft Personal Support remove the password or encryption?
No. Microsoft support cannot decrypt files, retrieve passwords, or remove Rights Management protection applied by an organization. This must be handled by the original account owner or the organization's IT administrator.
Is it possible to use third-party software to crack the Rights Management protection?
No. Microsoft Rights Management uses strong, enterprise-grade encryption that cannot be bypassed or cracked by third-party password removal tools. Authorized account credentials are strictly required.
What if I am the original creator but my work account was deleted?
If your former work account was completely deleted by the organization, only the IT administrator of that former organization can either temporarily restore the account or use their global admin privileges to decrypt and recover the file for you.
