Answer: Check your internet connection, verify email account settings (incoming/outgoing servers), clear stuck messages in the Outbox, or repair Outlook data files via File → Account Settings → Data Files → Repair.
3. Why does Outlook keep freezing or crashing?
Answer: Freezing can occur due to add-ins, outdated software, or corrupted profiles. Start Outlook in Safe Mode, update to the latest version, create a new Outlook profile, and repair PST files using the ScanPST tool.
4. Where did my emails go?
Answer: Missing emails may be in the Deleted Items or Junk Email folders. Use Outlook’s search feature, ensure you’re connected to the correct account, or restore from a backup PST file if necessary.
5. Why does Outlook keep asking for my password?
Answer: Repeated password prompts may indicate incorrect credentials, two-factor authentication, or cached credentials. Verify your password, remove and re-add your account, and clear stored credentials in Windows Credential Manager.

Answer: Check the file size limits of your email provider, temporarily disable antivirus scanning for attachments, save attachments locally before opening, or repair Outlook data files if attachments are corrupted.

Answer: Ensure the correct folder is selected, clear Outlook’s cache, re-sync your account, or import contacts and calendar events from a backup if necessary.
