Fix PowerPoint for Mac Redirecting MIP Files to Old Work Account
Question details
The user needs to stop PowerPoint for Mac from redirecting Microsoft Information Protection (MIP) files to the authentication page of an old organization.

- Product
- PowerPoint for Mac
- Device & OS
- macOS
- Scenario
- Opening a Microsoft Information Protection (MIP) encrypted presentation file after migrating to a new organization or changing accounts.
- Observed behavior
- PowerPoint continuously redirects the user to the single sign-on (SSO) login page of an old work account due to cached credentials or outdated Office activation data.
Before troubleshooting, ensure you have the correct login credentials for your current Microsoft 365 account. Save and close all active presentations to prevent any accidental data loss while resetting application data.
Clear Information Protection Application Data
Reset the cached MIP credentials directly from the PowerPoint application menu to force a fresh authentication prompt.
PowerPoint for Mac often retains old enterprise authentication tokens to speed up the login process. Clearing this specific data cache is the most direct way to stop the redirection loop.
Launch PowerPoint on your Mac. Navigate to the top macOS menu bar and click on 'Help'.
From the dropdown menu, select 'Clear Application Data' to open the reset options.
Check the box next to 'Information Protection' and confirm the action. This resets the MIP credentials so you can log in with your current organization's account upon reopening the file.

Use the Office License Removal Tool
If resetting application data fails, wipe out old Office activation licenses using Microsoft's official license removal tool.
Test with a New macOS User Profile
Create a new local user account on your Mac to determine if the issue is isolated to corrupt settings in your current profile.

Frequently Asked Questions
What is an MIP encrypted file?
MIP stands for Microsoft Information Protection. It is an enterprise security feature used to encrypt files and restrict access so that only authorized accounts within an organization can view or edit the documents.
Why is my Mac remembering my old organization's login?
PowerPoint for Mac stores authentication tokens in the application cache and the macOS Keychain to reduce the number of times you need to log in. If these tokens are not properly overwritten, they default to your old organization's SSO page.
Will removing Office license files delete my personal presentations?
No. The Microsoft Office License Removal Tool only deletes the hidden activation files that authenticate your subscription. Your personal .pptx files, documents, and data will remain completely intact.
