Outlook may repeatedly ask for a password due to several reasons. Here are some possible solutions:
Check your internet connection: Make sure your computer is connected to a stable and strong internet connection.
Check your login credentials: Ensure that you are using the correct email address and password for your email account.
Clear cached login credentials: Clear any cached login credentials stored on your computer by opening the Control Panel > User Accounts > Credential Manager > Windows Credentials, then find the entry for your email account and remove it.
Update Outlook: Make sure you have the latest version of Outlook installed. Go to the File menu > Office Account > Update Options > Update Now.
Disable Outlook Add-ins: Try disabling any Outlook add-ins that may be causing the issue by going to the File menu > Options > Add-ins > Manage COM Add-ins, then uncheck any add-ins you do not need.
Create a new Outlook profile: Sometimes, creating a new Outlook profile can help fix the issue. Go to the Control Panel > Mail > Show Profiles > Add, then follow the prompts to create a new profile.
Check your email account settings: Ensure that your email account settings in Outlook are configured correctly. Go to the File menu > Account Settings > Account Settings, then select your email account and click on "Change".
If none of these solutions work, contact your email provider's support team for further assistance.
