I have a list of 64 shared mailboxes. Management wants to know the owner of each of these mailboxes. I run the command "mailbox" | get-mailbox | get-mailboxpermission -owner. I am assuming the only way to get a list of owners for all mailboxes would be to add the "mailbox" for each mailbox and then run the command. While this could take some time, i'm ok doing the work. The problem i have is some mailboxes return the following error . I am not sure how to decipher this error. I know the mailbox exists and i copy and past the alias to make sure i'm typing it correctly. If i could get this list to work i can pipe it to a csv file. But, this error comes up even if i run the command only on one of the problem mailboxes. Any ideas?
