Hi @John_Turner
Welcome to the community.
13 years is a long time; it's no surprise you've built up a lot of old emails and attachments that may no longer be needed.
You can delete multiple emails at once by logging into your account via BT Webmail.
To make this easier, you can filter your emails by date to view messages from a specific time period. Once filtered:
Click on the checkbox next to the first email you want to delete.
Hold down the shift key.
Scroll down and click the checkbox next to the last email you want to delete.
Then click on delete or drag the selected emails to your trash folder.
