iPhone to 17.2.1 error “Attachment Is Over 100MB You must connect to a Wi-Fi network to send this attachment"

even though I am actively connected to a WiFi network (as clearly shown in the screenshot above). The SAME network I have used for YEARS to email larger attachments.

Connecting to Wifi is the first part and then getting connected to the Internet is the second

1. If you connect to Wifi, doesn't necessarily mean you are connected to the internet. If you are not connected to wifi could be a problem with iPhone settings or Router/Modem Settings
2. If you are not connected to the internet is the sole issue of Router / Modem Settings. Contact your ISP immediately

For your Internet connection.

• Over Cellular: contact your Carrier (Cellular Service Provider). The agency that issued the SIM to you
• Over WiFI: Contact your ISP (Internet Service Provider), the agency that provided the Internet Service on your Modem/Router to you

However --> Connect iPhone to the Internet - Apple Support

Check your WiFi Router / Modem for --> Recommended settings for Wi-Fi routers and access points ...

Re: "Attachment Is Over 100MB"

Wondering if the attachment is causing your message to exceed size limits set by your email account provider.

If so, there are a few other ways to send a large attachment.

Compressed files take up less disk space than uncompressed files:

This method can be useful for sending information over the Internet.

See: Zip and unzip files and folders on Mac: https://support.apple/guide/mac-help/mchlp2528/14.0/mac/14.0

You can use Mail Drop to send files that exceed the maximum size allowed by your email account provider.

Eg: Scroll to: "Send large email attachments using Mail Drop" in Apple support's online article (link below) for the details. (NB: You can turn Mail Drop on or off for an account. Choose Mail > Settings, click Accounts, select the account, click Account Information then select or unselect “Send large attachments with Mail Drop”.)

Add attachments to emails in Mail on Mac - Apple Support

Else: If the receiver uses a Mac, iPhone or iPad that is near to your own device:

You may be able to: Use AirDrop on your Mac to send files to devices near you - Apple Support

All the best :-)

You may want to scroll down in the article below, to see whether any of the reasons listed for why "Attachments might not be sent using Mail Drop" may apply:

Apple Support's article: Mail Drop limits - Apple Support

• Eg: says if: An uncompressed folder is attached to the message. 

Follow these steps to compress your attachments.

• if: Too many messages have been sent or the maximum number of recipients has been exceeded. Find out about mailbox size and message sending limits.

• The recipient’s email app might have a smaller message size limit that prevents the attachment from being delivered.

.... other reasons are given in the above article.
