From your post, I understand how frustrating this is, especially after removing the account and then being unable to add it back.
Have you tried the Q&A Assist suggestions under your post?
Just to make sure I’m guiding you correctly, could you please confirm:
- When you try to add the account again, what exactly happens? Do you get an error message, or does the process fail without completing?
- Is this a personal Outlook.com/Hotmail account, a work/ school account, or an account from another email provider?
Meanwhile, please try these steps next:
1, Confirm the account works outside Outlook first
Before adding it back, try signing in directly on the provider’s website (for example, Outlook.com or your email provider).
- If it doesn’t work there, the issue is with the account/password
- If it works, then the issue is with Outlook setup
2, Clear saved credentials (common cause when password won’t save)
Old credentials can prevent Outlook from saving the new password:
- Close Outlook
- Open Control Panel > Credential Manager > Windows Credentials
- Look for any entries related to your email account and remove them
- Reopen Outlook and try adding the account again
3, Test Outlook in safe mode
- Close Classic Outlook app completely
- Press Windows + R, type
outlook.exe /safe> press Enter - If it's stable in Safe Mode, disable add-ins (Go to File > Options > Add-ins > Manage: COM Add-ins > Go) and re-enable them one by one to find the culprit.
Please feel free to let me know how it goes. Thank you for your time and understanding.
