If you click Upload CSV in the ContactMonkey Web Add-in and nothing happens, this is a known issue in Classic Outlook that occurs when the Web Add-in pane is too narrow. Widening the Web Add-in pane lets the Upload CSV button work as expected.
Classic Outlook now requires the Web Add-in pane (the panel that opens beside your message) to meet a minimum size before it completes the upload request. When the pane is narrower than that minimum, the request doesn't complete.
This is an active known issue our team is working on. This article will be updated when a fix is released.
What you'll see
When you open the Web Add-in within Classic Outlook and click Upload CSV, the button appears unresponsive.
Who is affected
You may see this if both of the following are true:
- You're using the Web Add-in in Classic Outlook, and
- The Web Add-in pane is at its default or a narrow width.
Note: This issue only affects Classic Outlook. The Upload CSV button works as expected in New Outlook and Outlook on the web.
Workaround: Widen the Web Add-in pane
Stretching the Web Add-in pane wider gives Classic Outlook the space it needs to complete the Upload CSV request:
- Open a new message in Classic Outlook and open the Web Add-in.
- Hover over the edge of the Web Add-in pane until your cursor changes to a double-sided arrow.
- Click and drag the edge to make the pane much wider than its default size.
- Click Upload CSV.
- Browse and select your CSV file.
Tip: If the button still doesn't respond, maximize your Outlook message window, widen the Web Add-in pane further, and try again.
Next Steps
Once your file uploads, the Web Add-in automatically validates it and shows how many email addresses were processed. Continue composing and sending your email as usual.
