In this blog post we are going to tell
you how you can get rid of Exchange Server Errors 528 and 550.
Exchange server stores all data in its storage groups. All essential
data of Exchange Server's users is stored in exchange database files.
This type of errors comes when there is some corruption in its
database. Due to this error user is not able to access its mails and
important files and folders.
Case 1:-
When you try to restore your essential
data with the help of backup server it may be possible that
information store may fail to mount or start. This scenario may lead
to disaster/corruption in Exchange Server database. You may encounter
the following errors while restoring from backup server:
- As you start Exchange Server you may get Exchange error 550 message on screen.
- Or after deletion of log files, Exchange database doesn't come up and Exchange Error 528 pops up.
Main cause for the Exchange Server Error 550 is when user tries to run eseutil or Exchange directory
services with the help of backup software and Exchange server, backup
becomes inconsistent and fails to restore data.
And possible cause for Exchange
server error 528 is when edb.log and edb.chk files are lost that
are usually stored in Exchsrvr\Mdbdata directory.
Solution For Case 1:-
- Eseutil /r command to perform soft database recovery.
- Eseutil /p command for hard repair.
- Third-party Exchange Recovery Tool.
Case 2:-
Exchange error 550 is caused by mainly
connection error in external domain and domain server. Following are
some steps that user can try at his basic level:-
- Try to setup a telnet connection to the mail-server of that specific domain and check if it’s working. If not, suggest you contact your ISP to create one first.
- Check whether you are able to send a message via telnet to the mail server.
- Create a PTR record. If not, contact your ISP to create this.
- Try to telnet on that email server and send EHLO command.
- Examine that there should be no such issue for only one domain or multiple domains.
First run default command ESEUTIL
proposed by Microsoft, and if there is no effect than install any
professional third party tool such as Stellar Phoenix Exchange Server Recovery that is highly effective for both Exchange Server errors 528
and 550 and also available at an affordable price with its risk free
demo version.
