Working as an administrator of MS Exchange Server, the user finds himself in complete control. The server application is simple but highly efficient which helps the user to manage all the activities easily. However there is a situation when user is troubled while sending an email to a particular destination. While attempting to send an email user encounters an error stating:
Server error:’550 5.7.1 Unable to relay’
Cause:
The error is experienced when user tries to send an email to a Server located at outer domain. However the most probable cause of the error is corruption of Exchange Server database.
• The outgoing mail server does not recognize the user hence it does not allow him to send any information.
• The unavailability of recipient policy may also lead to the aforementioned error.
• Dirty Shutdown, Virus attack, Hardware malfunctioning may also lead to the corruption of Exchange EDB files and further cause occurrence of Error 550.
Solution:
User must check either of the below mentioned methods in order to overpower MS Exchange Server Error-550
• Method 1:- Run Eseutil/r and Eseutil/d command.
• Method 2:- Open ESM (Exchange System Manager) and then open SMTP server currently in use. Then Select 'Properties'-> 'Access'-> 'Relay'. Now, check if the "Allow computers which successfully authenticate to relay" option is enabled.
• Method 3:- Go for reliable third party recovery tool
Let us diagnose the above mentioned solutions according to their success percentage. Using free utility Eseutil, user may solve the minor issues but when we talk about major corruption of files the utility fails to perform. Also it damages the original data up to the extent that it cannot be retrieved further. Hence it is advisable to the user to maintain backup before performing any operation on the data. The second method is a bit technical hence we cannot expect novice user to perform the steps accurately. Therefore only option left with the user is to go for
