Hi guys,
I have a small problem with these events. I have a lot of warnings with 9042 and I found out that information is contained in event id 9025, so far so good. I found that the problem is because of one old mailbox from a user who is no longer working in the company, also his mailbox doesn't appear in Disconnected Mailbox. I have a name and GUID but running Get-Mailbox returned only "The operation couldn't be performed because object '.....' couldn't be found on 'DC' because the account is removed from the AD. So how I could get rid of this mailbox in order to stop all these events? Thanks in advance
