Why email stops working
Email can stop working because of password changes, account lockouts, full mailboxes, incorrect settings, internet issues, app problems, multi-factor authentication prompts, expired sessions or provider outages. Sometimes the email account is fine but the mail app on one device is not syncing correctly.
For small businesses, email issues can interrupt quotes, invoices, bookings and customer replies. It is important to know whether the problem affects one device, one user, or the whole business.
Safe checks you can try first
- Check whether the internet is working.
- Try signing in through webmail using a browser.
- Check whether the mailbox storage is full.
- Restart the device and reopen the mail app.
- Check for password or security prompts.
- Look in the Outbox for stuck messages with large attachments.
- Do not delete and re-add the account unless you know the password and recovery details.
Sending problems
If email receives but will not send, the issue may be a stuck Outbox message, attachment too large, incorrect outgoing server settings, blocked account, changed password or security policy. Business accounts may also block sign-in attempts that look unusual.
Receiving problems
If email sends but does not receive, check spam/junk folders, mailbox quota, forwarding rules, filters and whether messages arrive in webmail. If messages appear in webmail but not on the computer, the issue is likely the app or account configuration on that device.
How OCT can help
OCT can check email access, Outlook or mail app settings, account configuration, device-specific sync issues and common security blocks. If the issue is with the provider, OCT can help identify what needs to be reported or changed.
