My emails won't send – how can I fix that?
Most likely, your email is stuck in the Apple Mail app Outbox. The solution is to delete the email from your Outbox and try again.
Even if you are using a different app for your regular email, the issue here is with the Apple Mail app. This is the Apple Mail app:
Apple Mail won't let you delete the email from your Outbox while it's trying to send the email. The trick is to switch your device to Airplane Mode so that you can delete the email from the Outbox. Then force close the Apple Mail app (see instructions here: Force close an app), and try again.
Here is another tutorial on how to do so: http://theappfactor.com/how-to-fix-stuck-outbox-messages-on-iphone/.
We strongly recommend that you also check the following:
- Ensure that the document you are trying to send is not too large for your email server. Typically, email servers might refuse attachments bigger than 10-15 MB.
- Do you have a good network connection? If the document is more than a few pages, it might take a long time or even fail if your network connection isn't at 3G or Wifi.
- Is your email configured correctly for the iOS Mail app? You might need to fix your device's email configuration. Check that your email account is properly configured:
Open the Settings app
Under Mail, Contacts, Calendar, check that your email account is properly configured
Once this is done, open the Mail app
Send an email to yourself and check that you properly received it.
