Ok, go into the iPad Settings > Mail, Contacts and Calendars. Add a new account > Other > Add Mail Accounts
Enter your name, email, email password, and in the description - Karoo IMAP
Under incoming mail server...
Host Name - imap.karoo.co.uk
Enter your email and password again
Outgoing...
smtp.karoo.co.uk
Then, tap advanced. Under incoming settings...
SSL = off
Server port = 143
Now press done to save everything, you may get an error, that's fine.
Then, in your accounts list, tap your new Karoo IMAP account. In the box that opens, tap the SMTP menu (under outgoing mail server). Tap smtp.karoo.co.uk
Outgoing mail server is 25 & SS: should be off. Enter your email and password again.
Once this is done, you'll be accessing your email via the much better IMAP! It should resolve the issue ;-)
As Sooner Al says, it would be wise to replicate this on your other devices but not compulsarary.
