I changed the password for my BT account not realising that this changed the password to access my email account as well. After this, emails on my Macbook (2009 version) were not being updated. Trying to fix this - I clicked something (!) only for all the emails in the inbox to disappear!
I've tried re adding the email account in Internet accounts but it just gives the error - Account already exists.
From the Q&A's on this forum i think there is known problem with old Apple devices.
Is this the case?
thanks for any help at all.
Can you access your email account using web mail
