Email problems can come from DNS, mailbox settings, passwords, storage, spam filtering, or provider outages. Start with the basics.
Check Webmail
If webmail works, the mailbox is probably active and the problem may be with the device or mail client.
Check DNS
Confirm MX records still point to the correct provider. If nameservers recently changed, old mail records may have been missed.
Check Passwords and Storage
Expired passwords, full mailboxes, and incorrect server settings can all stop mail clients from syncing.
Check Sending Separately
Receiving and sending use different settings. SMTP problems can exist even when incoming mail works.
When asking for help, include the address, device or mail client, error message, and whether webmail works.
