Why can’t I open attachments in mail

Hello bernburra,

Thank you for reaching out in Apple Support Communities. We recommend to test this behavior on both cellular data and Wi-Fi. This can help determine if you're unable to open attachments in the Mail app.

In addition, are you unable to download attachments from your emails? Just to be sure, you can follow these steps to download attachments:

Download an attachment sent to you

Touch and hold the attachment, then choose Save Image or Save to Files.

If you choose Save Image, you can find it later in the Photos app. If you choose Save to Files, you can find it later in the Files app.

Tip: To open the attachment with another app, tap Share , then choose the app.

These steps are outlined here: Download email attachments in Mail on iPhone

We look forward to hearing back from you with an update.

Kind regards.

Greetings bernburra,

Thanks for following up and letting us know that the network may have been the culprit with being unable to open the attachments.

Cheers.
