- Observed behavior

Clear Windows Credentials and Reset Internet Settings
Resolves authentication conflicts caused by corrupted cached credentials or misconfigured network options blocking the sign-in connection.
Windows stores your login information in the Credential Manager. If these cached files become corrupted, they can cause Office login prompts to freeze. Additionally, outdated Internet Explorer/Edge background settings can interfere with the Microsoft authentication service.
Open any Office app like Word, navigate to File > Account, sign out of all currently displayed accounts, and close the application entirely.
Open the Windows Start menu, search for 'Credential Manager', and click on 'Windows Credentials'. Locate any entries starting with 'MicrosoftOffice15' or 'MicrosoftOffice16', click on them, and select 'Remove'.
Close all browsers. Open Control Panel > Internet Options. Under the General tab, click 'Delete' in the Browsing history section. Then go to the Advanced tab, click 'Restore advanced settings', click 'Reset', and check the box to delete personal settings.
Open Windows Settings > Accounts > Access work or school. Check the list of connected accounts and disconnect them if they are interfering with your personal Office 2019 login.

Frequently Asked Questions
Why does my Office 2019 sign-in window freeze immediately after typing my email?
This freezing is usually caused by conflicts with corrupted cached credentials in the Windows Credential Manager, issues with outdated Internet Options, or interference from connected work/school accounts in Windows settings.
Can I use Office 2019 without signing in?
Yes, Office 2019 can be used offline for extended periods without signing in. However, you may need to log in to access specific functions like online Help, cloud features, or when migrating your software license to a new computer.
Will resetting Internet Options delete my personal browser data?
When resetting Internet Options from the Control Panel, it will clear cached data, cookies, and browsing history for Internet Explorer/Edge, which is necessary to resolve Office sign-in connection bugs. It will not delete files from other browsers like Chrome or Firefox.
Does running a Quick Repair on Office delete my documents?
No, running a Quick Repair or an Online Repair only scans and replaces damaged application files in the Microsoft Office installation directory. Your personal Word, Excel, and PowerPoint files are completely safe and will not be altered.
