Email problem following update to 16.6

After updating both my iPhone and iPad to os 16.6, I can no longer send email using the Mail app, from my primary email account (with my ISP). I keep getting a message that the sender's address is invalid. I can still receive email from that account -- and send email using the devices that haven't been updated yet.


I have to think that something in the update is causing this issue. I went to my ISP's website, got the latest email setup settings, which appear to be the same as I have. I'm not going to update the other devices until this issue is resolved.


Is anyone else having this issue with the new update?

Start with initial fault finding:


What happens when you try to receive or send email? Do you see any errors - and if so, what do you see?


If email is failing to send or receive, you are likely to see indicative errors at the bottom of the mail sidebar - the wording of the error usually providing sufficient information to determine the nature of the problem.


Deleting and re-adding your email account is sometimes the easiest way to resolve a problem with a specific Mail account. After deleting the account, perform a forced restart before re-adding the email account to your iPad.


  • Delete account:

Settings > Mail > Accounts > [Your Mail Account] > Delete Account


  • Force restart the iPad:

Force restart iPad - Apple Support


  • Add Mail Account:

Settings > Mail > Add Account


Assuming that you are not using a POP3 mailbox, all your mail is stored on your Mail Providers Mail servers - with only a copy of this data residing on your devices. As such, deletion of the mailbox from your iPad will not cause any loss of data.



NB: Be aware that some email providers now require the use of App Specific Passwords when accessing mail over IMAP or POP3. If this applies to your email account, you will need to generate a unique password for your iPad email account - that will differ from your normal Account Password. As examples - AOL, Yahoo, Google, Microsoft all use App Specific Passwords when using anything other than their own email client Apps.


If you need to generate an App Specific Password, you’ll need to log-in to your Mail Providers account management webpage - using a web browser - and generate the Password from the appropriate account security page.

Thanks for the reply. I hope it will be helpful to the community.


My problem has been solved. It turned out the issue was at my ISP's end. I had an already-planned modem upgrade done a few days ago. The ISP had made changes at their end, requiring a modem replacement. Once the new equipment was installed, I was able to send email from both my iPad and iPhone again.
