Mail User Guide
If your email account exceeds the storage limits set by the account’s provider, you can take some actions in Mail to free up space on the account’s mail servers.
In the Mail app on your Mac, do any of the following:
How to free up space used by the Mail app on the Mac. If you use the built-in Mail app on your Mac, you might be clogging up your iCloud storage with useless junk and deleted mail. You can quickly clear out some space by erasing the old stuff. Launch the Mail app on your Mac. Click on Mailbox in the upper left side of your Mac's screen. Generally to find the Format button in Mail app, you must open a new email composition window, whether that’s to write a new email, reply to an email, or forward an email. If the Format button (the “A” button) is not visible at all, it may be because the Mail Toolbar is hidden in your Mac Mail app. To show the Mail Toolbar, do the following.
Delete large messages or messages with attachments, or move the messages to a mailbox on your Mac.
Tip: To quickly identify large messages, choose View > Sort By, then choose Size.
Delete attachments that you saved. Choose Message > Remove Attachments; the message remains in the mailbox and Mail indicates attachments were manually removed.
For IMAP accounts, be sure to download the attachments first—attachments are deleted from the mail server and can’t be retrieved.
Trim enabler 4 2 – write faster to any ssd hard drive. Empty your Trash mailbox. Messages you recently deleted are in the Trash mailbox but haven’t yet been removed from the mail server. Choose Mailbox > Erase Deleted Items, then choose to remove them from all accounts or a specific account.
For POP accounts, reduce the amount of time that copies of messages and attachments remain on the mail server before being removed. Choose Mail > Preferences, click Accounts, select the account, click Advanced, then choose a different option from the pop-up menu below “Remove copy from server after retrieving a message.”
To check the size of messages and mailboxes, view account information.
I have several email accounts that are linked to my Mail App on my MacBook Pro.
This has been on there for several years and it's taking up a huge space on my hard drive.
I've found the MAIL file and have backed this up. How can I reduce the size of this folder on my hard drive? Is there a way of deleting the folders on there or must I delete the emails on the Mail App.
Also if I delete the emails from places like gmail and hotmail on my Mail App does this delete them permanently or are they still accessible if I access them through safari?
Also any advice on how to stop this happening in the future?
Many thanks in advance!
