I just closed an Office file without saving it. Can I get it back?
You should be able to recover your file with a bit of luck. If you saved the document once, autosave might have done its job. Otherwise, try using AutoRecover or check your temporary files.
I can’t open an email attachment.
You may not have the software the file was created with. Right-click the document and select ‘Open With’ to see if there’s another option.
I’ve had an email telling me an account needs updating. Is it genuine?
Don’t click any links in the email. If you’re unsure, the safest thing is to visit the website by typing the URL into your web browser. Do not copy and paste.
