Search-Mailbox command now failing. Has something to do with attachment size

    问题

  • We have been using the command below for years searching through mailboxes to remove spam or possibly malicious emails. Always worked great. We run it first in logLevel Full mode and then add the -DeleteContent Switch.

    get-mailboxserver | Get-Mailbox -resultsize unlimited | Search-Mailbox -SearchQuery "From:"emailaddress.com" -TargetMailbox "Suspect Emails" -TargetFolder "Phish" -LogLevel Full

    Recently when running the command we are now getting the error below. I know the reason why we are getting the error. I just don't know what to do to fix it. The queries we are running now are returning much larger results. Basically every mailbox and it looks like it cannot create the Excel worksheet. If I run it on each mailbox server separately, it seems to run OK because I am only hitting half the mailboxes. Is there a swtich or setting I can implement to override this error?

    Cannot open attachment.

  • Hi shadowtuck,

    Could you use the command below to search for just one mailbox successfully?

    Search-Mailbox -SearchQuery {From:"xxx@xxx.xxx"} -TargetMailbox "xxx@xxx.xxx" -TargetFolder "xxx" -LogLevel Full

    I guess there has a limit about search-mailbox, if you can search for just on mailbox, you can use the script below to search for all mailbox:

    $mailboxes = Get-MailboxServer | Get-Mailbox -resultsize unlimited
    
    foreach($mailbox in $mailboxes){
    
    Search-Mailbox -Identity $mailbox.name -SearchQuery {From:"xxx@xxx.xxx"} -TargetMailbox "xxx" -TargetFolder "xxx" -LogLevel Full
    
    } 
    

    Regards,

  • Yes, I can search one mailbox. In fact, I can search over a thousand mailboxes but there seems to be a limit in regards to the creation of the attachment when loglevel is set to full.

    This is the problem I am trying to solve. I can run the command against a single mailbox with half our mailboxes on it and it works, but if I run it against all mailboxes, if fails creating the attachment.
