I've noticed this error on an Exchange 2007 box I have setup. Event log is flooded with this issue it appears almost 50 times per second.
This can't be good for the performance, lol.
Source: MSExchangeIS Mailbox Store
Logon Failure on database "DB\DB2db" - Windows account CAFENET\MAIL3$; mailbox /o=CafeCC/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=tlwbk.
Client Machine: MAIL3
Client Process: edgetransport.exe
Client ProcessId: 0
Client ApplicationId: Client=Transport
I know who's account it is (tlwbk), and they said it could be removed. But I'm not sure if that's going to solve this event log.
Is the account tlwbk being used in a service or task that typically triggers this error?
Searching around online, the articles I've found haven't made me sure of what the fix is.
