Dear Pasha,
Thank you for reaching out to the Microsoft Q&A forum. I’m sorry you’re running into error (0x80070057) “Sorry, something went wrong. You may want to try again.” in Classic Outlook for Windows—I know that’s frustrating, and I’m here to help.
To better understand and resolve this quickly, could you please confirm:
- Account type in Outlook: Outlook.com/Hotmail, Gmail/Yahoo (IMAP), or work/school (Microsoft 365)?
- When the error appears: during Send/Receive, adding the account, or opening Outlook?
- Your Outlook version/build (Outlook > File > Office Account).
Please also try these additional workarounds:
If this is a Gmail or Yahoo account in Classic Outlook
Start Outlook in Safe Mode to rule out add-ins
Repair the Outlook account/profile connection
- In Outlook: File > Account Settings > Account Settings > (Email tab) > select the account > Repair.
Create a new Outlook profile
- Windows Control Panel > Mail > Show Profiles > Add (create a new profile), then set Outlook to prompt or use the new profile and re‑add the account.
Repair Outlook data files if you use PST/OST
