Exchange 2010 mails bounce back with Mailbox disabled

This morning there was a strange problem, Users when trying to send emails are getting bounce back that mailbox they are trying to send is disabled:

Error:

#554-5.2.1 mailbox disabled 554 5.2.1 STOREDRV.Deliver.Exception:AccountDisabledException.MapiExceptionMailboxDisabled; Failed to process message due to a permanent exception with message Cannot open mailbox /o=First Organization/ou=Exchange Administrative Group.

when i checked the Active directory all users are not disabled, so i tried with login from webmail but still saying your mailbox is disabled. i noticed that all these users are on same database.

 

Solution:

Run the following command from Exchange powershell:

Clean-MailboxDatabase databasename

 

after running this command all emails are working fine

With Warm Regards
