Fix Outlook for iPad Not Sending Large Attachments to OneNote
Question details
The user is unable to send email attachments larger than approximately 10 MB from the Outlook app on iPad to OneNote using the built-in Send to OneNote feature.
- Product
- Microsoft Outlook and OneNote
- Device & OS
- iPadOS
- Scenario
- Attempting to export an email with a large attachment from the Outlook mobile app directly into a OneNote notebook on an iPad.
- Observed behavior
- Attachments over 10 MB are omitted or fail to transfer to OneNote, despite the exact same workflow functioning correctly on the desktop version of Outlook.
Verify the file size of the attachment in your Outlook email. If the file exceeds 10 MB, the direct Send to OneNote feature on iPad will automatically omit the file due to system limitations, and you will need to use a cloud-saving workaround.
Save to Cloud Storage and Insert Manually
Since the iPad app has a hard 10 MB limit, you can bypass this restriction by saving the file to OneDrive or SharePoint and linking it inside OneNote.
This method ensures that your large attachments are safely stored in the cloud while still being easily accessible from your OneNote notebook, avoiding the app-to-app transfer size limits.
Open the email in Outlook for iPad, tap on the large attachment, and select the option to save the file to your connected OneDrive or SharePoint account.
Launch the OneNote app on your iPad and navigate to the specific notebook and page where you want to store the information.
Tap the 'Insert' tab at the top of the screen, select 'File' or 'Link', and choose the large file you just saved to your cloud storage to insert it onto the page.
Use the Desktop Version of Outlook
The desktop client does not have the same strict 10 MB limitation as the iPad app, allowing large files to transfer seamlessly.
Experience Unrestricted Document Management with WPS Office
While Microsoft Office apps on mobile devices may impose strict integration limits, WPS Office offers a lightweight, all-in-one alternative. Manage your documents, PDFs, and cloud files seamlessly on your iPad without the hassle of app-to-app syncing restrictions.
- 1. Install the app: Download and install WPS Office from the App Store on your iPad.
- 2. Connect cloud storage: Sign in to your preferred cloud storage service like Google Drive, Dropbox, or OneDrive directly within the WPS app.
- 3. Manage large files: Open, edit, and organize your large documents in one unified workspace without worrying about attachment size limits.
Frequently Asked Questions
Why is the Send to OneNote attachment limit different on iPad compared to desktop?
Mobile and tablet applications often have strict memory and background processing limitations to ensure smooth device performance. Microsoft restricts the iPad app to a 10 MB payload for OneNote transfers, whereas desktop applications utilize greater system resources to handle much larger attachments.
Can I change a setting in iPadOS to increase this file transfer limit?
No, the 10 MB limit is hardcoded into the architecture of the Outlook and OneNote applications for iPad. There is no iPadOS setting or hidden app configuration that allows users to manually increase this threshold.
Where can I request Microsoft to increase the Outlook for iPad attachment limit?
You can submit a feature request directly to Microsoft's engineering team by navigating to the 'Help & Feedback' section inside the Outlook app settings, or by visiting the official Microsoft 365 feedback portal online.
Does this 10 MB limit apply to all file types sent to OneNote?
Yes, the limitation applies to the total data payload being sent through the Send to OneNote feature. Regardless of whether the attachment is a PDF, image, or Office document, the app will omit files that exceed the 10 MB threshold.
