Fix Excel Attachment Will Not Open in Samsung Email App
Question details
The user is unable to open an Excel email attachment in the Samsung Email app due to an incomplete download error caused by a stalled bulk email transfer between a NetZero server and Microsoft Outlook.
- Product
- Samsung Email App / Microsoft Outlook
- Device & OS
- Samsung S9
- Scenario
- Attempting to access a drafted or forwarded email containing an Excel attachment on a mobile device after a massive desktop email sync was interrupted.
- Observed behavior
- The Samsung Email app displays an error stating the attachment was not properly downloaded and fails to open the file. The email also appears missing from both the NetZero server and the Outlook desktop application.
Ensure your Samsung device has a stable Wi-Fi connection and verify that you have the login credentials for both your NetZero and Microsoft Outlook accounts before attempting to recover the missing file.
Recover the Attachment from Local Outlook Data Files
Since the email transfer was interrupted during a desktop sync, the file may be cached in a local Outlook Data File (.pst or .ost) rather than on the live server.
When Outlook downloads a massive number of emails (like a 20-year archive), it stores them in local data files on your hard drive. If a message gets stuck, checking previous backups of these data files is the most reliable way to recover the attachment.
Open the Control Panel on your Windows PC and search for 'Mail'. Click on 'Mail (Microsoft Outlook)' to open the setup window.
Click on 'Data Files' to view a list of all .pst and .ost files associated with your accounts. Note the folder paths shown under the Location column.
Open File Explorer and navigate to the directory where your Outlook data files are stored to see if there are any recent backups or archive files.
Open your Outlook desktop app, go to File > Open & Export > Open Outlook Data File. Select an older .pst file from before the transfer got stuck to retrieve the missing Excel attachment.
Verify Original Webmail Servers
Check if a copy of the drafted email is still lingering on the source web servers before it was pulled to the desktop.
Clear Samsung Email Cache and Force Sync
If the email server still holds the attachment but the Samsung app displays a 'not properly downloaded' error, clearing the local app cache can force a fresh download.
Use WPS Office to Open Mobile Excel Attachments
If you are struggling with complex Microsoft Office sync issues or heavy mobile applications, WPS Office is the perfect free, lightweight Microsoft Office alternative. It features a familiar UI, seamless migration, and effortless Excel attachment viewing directly on your Android device.
- 1. Install WPS Office: Download and install the free WPS Office application from the Google Play Store on your Samsung device.
- 2. Save the Attachment: In your email app, tap 'Save' or 'Download' on the fully synced Excel attachment to store it in your phone's local memory.
- 3. Open Seamlessly: Locate the downloaded file in your file manager or notification panel and tap it to instantly view and edit your spreadsheet in WPS Office.
Frequently Asked Questions
Why does my Samsung Email app say the Excel attachment is not properly downloaded?
This error occurs when the email sync is interrupted before the file fully transfers to your device. It frequently happens during massive bulk email downloads, network drops, or when the source email server times out, leaving behind an incomplete file placeholder on your phone.
Do emails stored in the Outlook desktop app automatically sync to Outlook.com?
No, Outlook.com does not automatically mirror copies of messages stored exclusively in local desktop Outlook data files (such as .pst files). You must use an Exchange or IMAP account configuration to ensure your folders sync correctly to the web server.
How can I find out which email account is associated with my desktop Outlook?
Open your Outlook desktop app, click on 'File' in the top left corner, and select 'Account Settings' followed by 'Account Settings' again in the dropdown. The 'Email' tab will list all connected email accounts and specify which one is set as your default.
