This account has been disabled or discontinued 550 #5.1.0 Address rejected [email] A message that is related to the same problem we are describing is this one, 5.1 0 unknown address error 550 invalid recipient where the recipient’s host (i.e., email server) doesn’t exist: Sorry, I couldn't find any host named [host]. (#5.1.2) If you got the email address from a real person, most likely there is a typo somewhere. Double check the email address you typed. If you obtained the address by phone, you may have misheard the name or a letter and ended up writing down the wrong email address. However, if you obtained the recipient’s email from a website, from a magazine, an advertisement, etcetera, and you double-checked it to make sure there is no typo, this means that the email simply doesn’t exist.

There are many reasons why 5.1 0 Unknown Address Error 554 happen, including having malware, spyware, or programs not installing properly. You can have all kinds of system conflicts, registry errors, and Active X errors. Reimage specializes in Windows repair. It scans and diagnoses, then repairs, your damaged PC with technology that not only fixes your Windows Operating System, but also reverses the damage already done with a full database of replacement files.
A FREE Scan (approx. 5 minutes) into your PC's Windows Operating System detects problems divided into 3 categories - Hardware, Security and Stability. At the end of the scan, you can review your PC's Hardware, Security and Stability in comparison with a worldwide average. You can review a summary of the problems detected during your scan. Will Reimage fix my 5.1 0 Unknown Address Error 554 problem? There's no way to tell without running the program. The state of people's computers varies wildly, depending on the different specs and software they're running, so even if reimage could fix 5.1 0 Unknown Address Error 554 on one machine doesn't necessarily mean it will fix it on all machines. Thankfully it only takes minutes to run a scan and see what issues Reimage can detect and fix.
A Windows error is an error that happens when an unexpected condition occurs or when a desired operation has failed. When you have an error in Windows, it may be critical and cause your programs to freeze and crash or it may be seemingly harmless yet annoying.
A stop error screen or bug check screen, commonly called a blue screen of death (also known as a BSoD, bluescreen), is caused by a fatal system error and is the error screen displayed by the Microsoft Windows family of operating systems upon encountering a critical error, of a non-recoverable nature, that causes the system to "crash".
One of the biggest causes of DLL's becoming corrupt/damaged is the practice of constantly installing and uninstalling programs. This often means that DLL's will get overwritten by newer versions when a new program is installed, for example. This causes problems for those applications and programs that still need the old version to operate. Thus, the program begins to malfunction and crash.
Computer hanging or freezing occurs when either a program or the whole system ceases to respond to inputs. In the most commonly encountered scenario, a program freezes and all windows belonging to the frozen program become static. Almost always, the only way to recover from a system freeze is to reboot the machine, usually by power cycling with an on/off or reset button.
Once your computer has been infected with a virus, it's no longer the same. After removing it with your anti-virus software, you're often left with lingering side-effects. Technically, your computer might no longer be infected, but that doesn't mean it's error-free. Even simply removing a virus can actually harm your system.
Reimage repairs and replaces all critical Windows system files needed to run and restart correctly, without harming your user data. Reimage also restores compromised system settings and registry values to their default Microsoft settings. You may always return your system to its pre-repair condition.
