Since incoming mail works and outgoing mail succeeds via another client, your mail server and credentials are fine. The failure is localized to Outlook—typically caused by outbound SMTP authentication unlinking, an SSL/TLS port mismatch (e.g. port 25 blocked vs 587/465), or a hung spooler state in the Outbox. ✅ Audit your Outlook account settings, ensuring SMTP authentication is explicitly matched to incoming credentials with correct SSL/TLS encryption ports. ✅ Inspect third-party add-ins, send/receive group schedules, and clear stuck items blocking the mail queue. ✅ Test and repair the Outlook profile, backing up your local PST/OST data and address books before applying any profile changes. ✅ 10+ years production experience | 400+ completed projects | 320+ five-star reviews ✅ Microsoft® Certified: MCSA | MCSE | MCT & cPanel Certified (CWSA-2) Is this account configured via IMAP, POP3, or native Microsoft 365 Exchange, and do the outbound messages sit stuck in your Outbox or disappear completely? I can deliver this in 1 day for 90 USD and can jump on it right now.

Hi There! I specialize in diagnosing Outlook email and account configuration issues, with 9+ years of experience, 450+ completed projects, Top 1% verified freelancer. Since you can receive emails and send successfully through another client, I’ll isolate whether the problem is Outlook’s profile, SMTP/authentication settings, cached credentials, add-ins, or connectivity. I’ll verify the account configuration, test the sending path, check for configuration conflicts, and fix the root cause rather than applying a temporary workaround. I’ll then confirm reliable sending and explain exactly what was changed. Which Outlook version are you using, and is the account Microsoft 365, Exchange, Gmail, or another provider?

Hi, I’m a Microsoft Cloud / M365 Engineer with extensive experience troubleshooting Outlook, Exchange Online, Microsoft 365, authentication, DNS, and email-delivery issues. Since email works from another client but not Outlook, I’ll focus specifically on the Outlook configuration and client-side/authentication path rather than making unnecessary changes to the mail service. I can diagnose and resolve issues related to: Outlook account/profile configuration SMTP/authentication and connectivity Cached credentials/tokens Outlook profiles and data files Add-ins or local configuration blocking sending Exchange/Microsoft 365 settings where applicable Send/Receive configuration and message queue issues I’ll verify sending and receiving after the fix and explain what caused the issue. I’m available to start immediately and can troubleshoot this through a remote session if required. Best regards, Kashif

Hi ClientFirstName, I can see the real pain point here: Outlook is still receiving mail, so the account itself is alive, but something in the send path, profile, or auth chain is silently breaking. I’ve handled Outlook and mail-client issues like this by checking SMTP/auth settings, cached credentials, send/receive profiles, server sync behavior, and any hidden connectivity or policy conflicts. I’ll start by isolating whether it’s an Outlook profile issue, a server authentication problem, or a local client configuration conflict, then fix it and verify sending from Outlook end-to-end. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. Could you share whether this is Outlook desktop or web, and which email provider you’re using? Also, are you on IMAP, POP, or Exchange, and does Outlook show anything in the Outbox when you try to send? Looking forward to your reply so we can finalize the exact plan. Thanks, Asad

@rimiloca

Hi, since the same account sends from another client, I would first isolate Outlook-specific causes: queued messages, send/receive mode, profile settings, add-ins and authentication. I can troubleshoot one account/profile, preserve existing mail and verify sending with a test message to a recipient you approve. $75 covers a guided troubleshooting session and a short fix summary within a day. Which Outlook version, operating system and mail provider are you using?

Being able to send from another email client but not Outlook usually points straight at something local to the app itself, a stuck outgoing server setting, a corrupted profile, or an SMTP authentication issue, rather than anything wrong with the account or password. The fix would start by verifying outgoing server and port settings, then checking for authentication mismatches or a corrupted send queue that's silently blocking outbound mail without throwing an error. If the account configuration checks out clean, the Outlook profile itself would get rebuilt or reset, since that resolves this exact symptom more often than a settings tweak does. Once sending is confirmed working, everything gets tested and explained clearly so it's understood what caused it and how it's resolved. Is remote access available now to start diagnosing, or would screen share work better to walk through it together?

@aimansulaiman

Hello, I can diagnose and fix the Outlook issue where emails are received successfully but cannot be sent, even without an error message. Since sending works through another email client, I’ll focus on the Outlook configuration, authentication, SMTP/Exchange connection, and local client issues rather than making unnecessary account changes. I’ll systematically check the account configuration, outgoing server/Exchange settings, authentication, ports, encryption, cached credentials, Outlook profile, add-ins, connectivity, and relevant Windows/Office components. I’ll also check whether DNS or server-side restrictions could be contributing to the problem. After identifying the root cause, I’ll apply the appropriate fix and test sending and receiving from Outlook with real messages. I’ll also verify that there are no recurring authentication, connectivity, or configuration issues. I’ll explain clearly what caused the problem, what was changed, and any steps needed to prevent it from happening again. I’m comfortable with Outlook, Microsoft Exchange, DNS, email configuration, Microsoft 365/Office, and technical troubleshooting, and I can start immediately.

@nicolasarmandoc

Hello, I can diagnose the Outlook sending issue systematically, especially since receiving works and another email client can send successfully. I’ll check the Outlook account configuration, SMTP/authentication settings, cached credentials, Outlook profile, send/receive configuration, connection status, and any relevant Microsoft 365 or Exchange settings. I’ll also verify whether antivirus, firewall, DNS, or a local Outlook issue is interfering with outbound mail. I’ll make only targeted changes, test sending and receiving after each fix, and confirm the account is working reliably from Outlook before finishing. I’ll also explain the root cause and the changes made so you can avoid the issue recurring. Is this Outlook account connected to Microsoft 365/Exchange, IMAP, or another email provider? Nicolas
