Observed behavior

Solution 1Recommended

Download the Attachment and Verify the File Extension

Saving the file locally helps identify its true format and bypasses email client preview errors.

Many email clients struggle to preview certain file formats directly in the browser or app. Downloading the file allows you to see the exact file extension and choose the appropriate software to open it.

1
Download the file

Click the 'Download' or 'Save As' icon on the email attachment instead of clicking the file name to preview it.

2
Locate the saved file

Open your device's Downloads folder or the specific directory where you saved the attachment.

3
Check the file extension

Look at the end of the file name (e.g., .docx, .xlsx, .zip) to determine what kind of document it is.

4
Open with a compatible app

Right-click the file, select 'Open with,' and choose an appropriate application such as a dedicated document editor or spreadsheet program.

Frequently Asked Questions

Why do some email attachments not open directly in my browser or mail app?

Web browsers and basic mail applications only support native previews for common formats like standard PDFs or images. Complex spreadsheets, password-protected files, or proprietary document formats require you to download the file and open it with a dedicated office suite.

How can I safely open a password-protected bank statement?

First, download the file to your device. Open it using a compatible PDF or document reader. When prompted, enter the password provided by your bank, which is typically a combination of your account number, phone number, or a custom PIN.

What does it mean if a downloaded bank attachment shows up as a ZIP file?

Banks sometimes compress large documents or multiple statements into a single ZIP file for faster and safer emailing. You will need to extract (unzip) the file using your operating system's built-in extraction tool or a third-party app before you can view the actual documents inside.
