Email Troubleshooting

Email Problems, Traced to the Actual Cause

Mail that stopped sending, a mailbox that will not sync, messages disappearing, or a client not receiving anything you send. Fixed at the mail account level, not just the app.

Symptoms

Email Faults We Are Called About

Email breaks in a handful of specific ways, and each points somewhere different.

It receives but will not send

Almost always the outgoing server settings, the port, or authentication — often after a provider changed their requirements. Distinctive because incoming still works, which tells us the account itself is fine.

Nothing has arrived for hours

A mailbox that has stopped syncing while the webmail shows new messages. A password change, an expired token or a client that lost its connection and never told you.

Messages have disappeared

Mail vanishing from a folder, or an archive that emptied itself. Usually a rule, a sync conflict between two devices, or a mailbox that hit its storage limit — and usually recoverable.

Your mail is going to spam

Recipients not receiving what you send, or finding it in junk. For a business this is a domain reputation and authentication problem, not something a mail client setting can fix.

Recipients get mail you did not send

Treat this as urgent — it means the account is compromised. There is usually a hidden forwarding rule behind it, and removing the malware alone does not remove that.

It works on the phone but not the computer

Two different configurations against the same mailbox. Very informative: it proves the account and password are fine and narrows the fault to the desktop client.

Approach

The Account Comes Before the App

Reinstalling the mail client fixes almost nothing.

Most email problems live at the mail account, not on the computer — server settings, authentication, storage limits, rules and forwarding. We check those first, from the webmail side, which immediately tells us whether the computer is even involved.

Where the account is healthy, the fault is in how the client is configured, and that is quick to correct once we know that is where to look. Where the account is not healthy, no amount of work on the computer would have helped.

Email Questions

Recovery, spam, migration and compromised accounts.

Still not sure?

Describe the problem and we will tell you what it takes to fix it — before any work starts.

Can you recover deleted emails?

Often, yes. Most providers keep deleted items recoverable for a period beyond the visible trash, and mail lost to a sync conflict frequently still exists on another device or on the server. The sooner you stop using the mailbox, the better the odds.

For a personal address it is usually content or sending behavior. For a business domain it is nearly always missing or misconfigured authentication records, which is a domain-level fix rather than anything on your computer.

Treat the account as compromised and call. There is usually a hidden forwarding rule and an active session behind it, both of which survive a malware clean-up on the computer. See Virus & Malware Removal for the full clean-up.

Yes — mailbox migration with folders, history and contacts preserved. For business domains this includes the DNS and authentication side so mail keeps flowing during the change.

That is actually helpful: it proves the account and password are fine, so the fault is in the laptop's configuration. Those are usually quick fixes and often resolvable in a remote session.

Nearly always. Email is one of the best candidates for a remote session — no visit needed and usually resolved the same day.
