Exchange server is becoming famous because of its user compatibility but it becomes irritating when you are working very heartily and sudden a error message pop up to disturb you.
It is a very common thing. Take one example of the scenario. Once I got stuck and the following error message appeared on my screen:-
Event ID: 1088
Source: MSExchangeIS
Type: Error
Category: General
The information store could not be loaded because the distinguished name(DN)of message database
/O=org_name/OU=site_name/CN=RECIPIENTS/CN= does not match the DN of directory
/O=org_name/OU=site_name/CN=RECIPIENTS/CN=.
