503 valid rcpt command must precede data outlook как исправить
For those that are tearing their hair out when getting the “503 valid RCPT command must precede DATA” error (we’ll refer to it as simply the 503 error going forwards) when trying to send email, here are some common solutions that will hopefully get you back up and running. If these don’t work, or you need more detail on any of these steps, please read the rest of this article, and its comments, for some more in-depth solutions.
- Apostrophes – remove any apostrophes (single quotes) or other non-alphabetic characters from your email account name(s).
- VPN – if your system is trying to connect via a VPN network while you’re sending email, you may get this error. Try disconnecting the VPN before sending/ receiving mail.
- Full mailbox – make sure the mailbox of the affected account is not full or has met/ exceeded its quota. You can uncheck the following option to make sure a copy of all your emails is not being left on the server (note that since the email will be downloaded to your PC after this setting change, you won’t be able to access your emails from another location if you do this). In Outlook, browse to Tools > Account Setting > More settings > Advanced > uncheck “leave a copy of this message on the server.”
- SMTP port – use port 26 (instead of the default 25) for outgoing mail.
- Server authentication – setup your outgoing mail to use outgoing server authentication (sends mail by logging in with your email address and password). In Outlook, browse to Tools > Account Settings > More settings > Advanced and change the outgoing server to ‘Auto.’ Next, browse back to More settings > Outgoing server and check the “My outgoing server uses the same authentication as my incoming server” box. If you select to have Outlook “remember your password” you won’t have to type it in every time you send an email.
- Sender matching – make sure you’re sending from the same email address that the recipient sees your email coming in as (ie. don’t make the “from” field differ from the email address used in your outgoing mail settings).
- Outlook PST files – sometimes the 503 error will occur if you have a corrupt outlook PST (mail archive) file. Try repairing the file.
If none of these approaches work, or you need more detail on a particular step, please read the rest of this article for some additional suggestions.
Option: Use Spam Bully for Outlook and Outlook Express
The 503 valid RCPT command must precede DATA error is a common one that often occurs as a result of the spam software you’re using, or as a result of Outlook’s default spam utility. We recommend giving Spam Bully a try. You can try it for free, and it’s one of the better known and more powerful spam filters. You can nail two birds with one stone – get rid of this annoying error and get rid of your annoying spam messages at the same time. Look at the error as a blessing – it helped you find Spam Bully :).
503 valid RCPT command must precede DATA
We recently got this error when trying to send an email in Outlook. The culprit? Apparently this occurs when a server is expecting to receive mail before sending. This is usually results from server authentication priorities (for example, you attempt to send mail before your “spam filter” has finished its receiving process.)
Solutions to resolve the 503 RCPT error
- Pop before SMTP — Run a check for new messages (F9 key in Outlook) before sending your message and restart and rerun your spam filter application. Your IP address is entered in a relayhosts file, allowing email to be sent from your address for up to half an hour.
- If the problem still persists check “my server requires authentication” to authenticate automatically. With this setting you can bypass the check above and send mail without having to “pop” your mail box first. You can also try changing the outgoing port from 25 to 26, since some ISP’s block this port.
- Several of our readers have pointed out that it may help to remove apostrophes from your email account names (and ask senders to remove them if you’re having trouble receiving emails from them).
- If you’re on a VPN, try disconnecting from the VPN prior to using your mail program.
- Your mailbox may be full – try clearing out messages or asking your mail service provider to increase your mailbox limits.
- If you are using multiple mailboxes, make sure these fixes/ settings are applied to each one of them, especially the “default” one.
- Finally, if using a mail screening utility such as Mail Washer, you may want to disable the “automatically check at intervals” setting and check mail manually. If the system checks mail while you are sending you may get this error.
If these don’t work, check your mail server
If none of the above work we recommend contacting your hosting provider. Your mail services account needs to be set up properly (associated with the right user name, etc.). We encountered this exact problem when switching hosts once – the mail server configuration got goofed up, and none of the above solutions worked. In the interim (until settings are fixed by your hosting provider) you can adjust your outgoing mail server to reflect that which your ISP uses, which should let you send mail again through your local client (Outlook, but not from the server (Webmail)), until the problem is fixed.
Install anti-spam software
As mentioned previously, to keep your mail system running smoothly, and to help you get rid of various email related errors, including the 503 valid RCPT error, we recommend installing a solid anti-spam solution. Anti-spam software is affordable, but your email and privacy are priceless. Don’t let the spammers get the best of you. For a limited time, get a free trial of Spam Bully.
We are having intermittent sending issues with all accounts on our domain, and constant issues on one account all using Outlook.
Every message sent to an external domain returns undeliverable with the following message.
'503 Valid RCPT command must precede DATA'
I have tried the following:
- Verifying SMTP port 26 is selected instead of the default of 25.
- Verifying 'My outgoing server requires authentication' and 'Use same settings as my incoming mail server' are enabled
- Settings for POP3, POP3S (SSL), IMAP, IMAPS (SSL), SMTP, and SMTPS (SSL)
- Creating new profile
- Verifying our domain was not SPAM blacklisted
Nothing has worked. I have called our service provider and they insist that the issue is on our end. They tested sending from our accounts in their building and it works fine.
I finally tested settings in Thunderbird and we are able to send externally through all accounts on all machines.
While it does work in Thunderbird, that is not an acceptable solution. Considering we have changed nothing with our account settings, I can't see why this problem would turn up.
I'm running out of ideas at this point and would appreciate any feedback.

But you were able to open the Outlook application, right? And the error you have sent is when you are trying to send an email?
Do you happen to know who is your mail provider? and have you tried using webmail?

The outlook error 503 valid RCPT command must precede DATA is usually encountered while sending email simply implies that the message did not reach its intended destination or recipient.
Amy Dennis
Apr 20, 2022 • Filed to: Recover Emails • Proven solutions
The outlook error 503 valid RCPT commands must precede DATA is usually encountered while sending email simply implies that the message did not reach its intended destination or recipient.
As ugly as the error message sounds, you need not fret if you get the Outlook error 503 message as this may happen to any user due to several reasons.
If you are using the Outlook Express on your PC and receive this message while sending an email, this article is especially for you. We will extensively discuss the cause of Outlook error 503 and how to fix the error.
Major Causes of Outlook Error 503 valid RCPT command must precede DATA
Usually, when you get the Outlook error 503 message while trying to send emails, it may be as a result of any of these two major reasons listed as follows:
- You need to confirm the email first before sending an email (checking email first is one of the numbers of ways email providers can use to secure your email account). If you did not verify the email before sending, you may receive the Error 503 Outlook message.
- The most common reason for this message is wrongly or improperly setting up the email client for SMTP authentication.
These two are the causes of the Outlook error 503 valid RCPT commands must precede data. Let us now discuss how to fix this error.
How Do I Fix Outlook Error 503 valid RCPT command must precede DATA?
Usually, the Outlook error 503 problem arises as a result of some errors in the settings connected to the email server. The email cannot be sent because of a few trivial mistakes, as well. Here are some arranged solutions which have been tested to remove and fix the 503 error Outlook problems;
1. Remove Apostrophes
Most users who had the error 503 Outlook issue have found this very useful. While inputting the name of the recipient for the email make sure you remove apostrophes. Also, should the sender of the email inform you that he or she cannot seem to send an email, ask them to remove any apostrophes present.
Confirming if apostrophes are used can solve this unwanted problem. After removing the apostrophes, you can go ahead to confirm if you can send the email.
2. Switch off your VPN
VPN connections help make you anonymous online. If you are using any and you encounter the 503 Outlook error, make sure you turn off the VPN connection because a VPN connection can malfunction at any time as a result of some security measures. After turning your VPN off, try sending an email again or confirm if the error 503 message still appears.
3. Check your Mailbox
Is your mailbox full? If yes, you need to have it cleared out immediately. The 503 valid RCPT command must precede data error may also arise due to this seemingly minor issue.
Using Outlook to send an email, confirm that copies of emails are not saved on the server by;
- Clicking on the file option
- Clicking on the account settings option
- Clicking on the select menu setting option
- Unmark the checkbox next under the advanced option next to the leave a copy of this message on the server.
After following these processes listed above, try to resend the email or refresh your mailbox after clearing out your mailbox to confirm if the error 503 outlook problem persists.
4. Confirm Before SMTP
Before attempting to send a new email to anyone, it is important you confirm if there is any new message in your mailbox. Using Outlook, press the F9 key from the keyboard to perform that same task.
After that, you need to reboot the email service. Remember to run the spam filter on the email application which may take up to 30 minutes to reach completion and allow it reset to be able to send emails like as previously. After this, you may attempt to send the email.
5. Configure SMTP Authentication
This happens to be the most helpful fix to completely obliterate 503 valid RCPT commands that must precede DATA. As a result of incorrect authentication of SMTP, a lot of users have had to deal with this problem. To authenticate the email service simply navigate to the ‘My server requires authentication’ option.
Also, you may decide to change the outgoing port from 25 to 26. This swift change can relieve you from the hassle instantly. Sadly, some Service Providers may not support port 25 for email services.
Should you, however, use the Outlook 2016 application, then here is an excellent solution to resolve issue 503 valid RCPT command must precede DATA. To configure your SMTP and resolve 503 issues, follow the steps as listed below;
- Click your particular email account as shown from the Account Settings window then click the account and choose the ‘Change’ option. Next, choose the More Settings option.
- Next, navigate to the tab labeled Outgoing Server.
- Ensure that you mark the checkbox which is seen next to the ‘My outgoing server (SMTP) requires authentication’. Then, choose the option labeled ‘Use the same settings as my incoming mail server’. After this, continue with the Advanced tab.
- Below the Advanced tab, you have to select the ‘Outgoing Server option’. Make sure you set its port as 465. Also, ensure you choose the SSL option from the ‘Use the following type of encryption’ menu. Then select the OK button.
- After this, continue with the Next option from the Internet Email Settings window. Clicking the finish option completes the process.
6. Try the professional Outlook repair tool
Various reasons can cause Outlook error 503 valid RCPT command error. But you can fix the problem using the best third-party tool like Stellar Outlook Repair. It scans all the corrupted PST files, repairs, and restores all mailbox contents speedily.
The repaired email attachments are saved as new PST files. You can then import them in Microsoft Outlook.
Step 1: Add .pst File
Launch the Stellar Outlook Repair tool. Click 'Select Outlook PST' in the home tab. A pop-up window will appear. It asks you to Browse or Find the PST file for data recovery.
Step 2: Repair the pst File
Now hit the Browse button if you know the location. If you do not know, click Find to search the PST.
Then, click Repair to start the PST repairing process for Microsoft Outlook mailbox recovery. The scan time depends upon the PST size and extent of corruption data.
Step 3: Preview and Save
