Deleting or removing an email account from Outlook will stop synchronizing new emails from the account.

You'll also lose access to cached content, including emails, attachments, and calendar items.

Make sure to back up your important emails and attachments by exporting them to a local PST file.

If your email account is linked to any subscriptions or contacts, update the mailbox information with them before deleting it.

And don't forget to close all Office applications, including Outlook, before removing the account.
