Hello @MICHAEL THOMAS,
I hope you are doing well.
To help us provide the most accurate and effective solution for your issue, could you share a bit more detail about your setup:
- What type of drives did the user lose access to (mapped network drives, shared folders, external drives, NAS devices, etc.)?
- Are the missing drives no longer visible in File Explorer, or do they appear but cannot be accessed?
- Which version of Windows is the affected user running?
- Was Microsoft 365 installed as a new installation or an upgrade from a previous Office version?
- Is the issue affecting only one user, or multiple users on the same network?
- Are there any error messages displayed when attempting to access the drives? If so, please provide the exact wording or a screenshot.
- Can the user access the shared drives by manually entering the network path (for example,
\\server\share)? - Were any recent changes made to the computer besides the Microsoft 365 installation, such as Windows updates, account changes, or security software updates?
This additional context will help us understand your environment and the troubleshooting steps already taken so we can tailor the guidance to resolve the issue effectively.
In the meantime, while we wait for your update, please review Microsoft's troubleshooting guidance for Microsoft 365 installation and setup issues: Troubleshoot issues you might see when you run Office 365 desktop setup | Microsoft Support
Looking forward to your response so we can get this sorted out for you together.
Kind regards.
