If your TalkTalk email account is set up in the Mail app using IMAP (which is the standard and recommended setup), then:
✅ No — you will not lose your email folders or saved emails.
IMAP stores all your emails and folders on the TalkTalk server, not on the device.
Removing the account from your iMac simply removes the connection — not the actual emails.
When you add the account back in, the Mail app will:
- reconnect to the TalkTalk server
- re‑sync all your folders and emails
- restore everything exactly as it appears in Webmail
⚠️ Only exception
If the account was set up using POP (older method), then emails may have been downloaded and stored locally on the iMac.
Most users are on IMAP, but it’s worth checking.
👉 To check if you’re using IMAP or POP:
On your iMac Mail app:
- Open Mail
- Click Mail (top left) → Settings
- Select Accounts
- Choose your TalkTalk email
- Look for Account Type: IMAP or POP
