Frequently Asked Questions
Why do Office apps take so long to sign in on Windows 11 but not Windows 10?
This issue is often related to how Windows 11 handles modern authentication and credential caching, or it may stem from a specific bug in certain Office update channels like the Monthly Enterprise Channel.
Will using the Reset option in Windows Settings delete my Office documents?
No. Using the Repair or Reset options in Windows 11 only affects the application files and internal configurations. Your personal documents and files saved locally or on OneDrive are completely safe.
What if reinstalling Microsoft 365 doesn't fix the slow sign-in?
If resetting and reinstalling do not resolve the issue, and multiple users in your organization are affected, it is likely a broader deployment issue. You should consult your IT administrator to investigate the specific Windows 11 build and Office channel compatibility.
