On your Apple device you may repeatedly see an error pop up on your screen ‘Cannot Verify Server Identity – The identity of
mail.tstnet.co.uk cannot be verified’. If you are using a different domain than tstnet.co.uk, the message will be slightly different.
To resolve this issue, the incoming and outgoing hostnames need to be changed. If you have a tstnet.co.uk email address, the hostname needs to be changed to mail37.extendcp.co.uk
To make this change on your Apple device:
- Tap ‘Settings’ on the Home Screen
- Scroll down the Settings list and tap ‘Mail’
- Tap on ‘Accounts’
- Select the email account that needs to be amended. In our example, this would be the tstnet.co.uk account
- Tap ‘Account’
- Tap Host Name and then change it. If you have a tstnet.co.uk, this needs to be changed to mail37.extendcp.co.uk. For other domains, please get in touch and we will let you know what the host name should be. Tap ‘Done’
- Scroll down to ‘Outgoing Mail Server’ and tap ‘SMTP’
- Tap ‘Primary Server’
- Make sure the ‘Server’ slider is ‘On’ and enter the mail37.extendcp.co.uk (or alternative) host name
- Tap ‘Done’. Go back to the mail account settings and tap ‘Done’
- The settings changes have been completed and you should be OK to send/receive email without the warning message
