If you’re receiving duplicate emails even though you only have one account set up, here are some common causes and remedies:
- Check your filters and make sure that emails aren’t being accidentally forwarded or duplicated.
- Check your Rules and make sure that emails aren’t being accidentally filtered into a folder.
- Check your synchronization settings and make sure that emails are not being copied from one client to another.
- Clear your mailbox cache and remove any duplicate emails that may already be in your inbox.
- Check for spam messages that may be targeting your mailbox.
