Hello,
I did import mailboxes as PST from one domain to another "different domain", everything is working find but when the user "on the other domain" click new mail, then it shows him the old "first domain" email address "maybe cached emails". for example, i did export user@domain.com and imported to user@contoso.com, now when the user@contoso.com tries to send mail (click to:) then it will shows him last emails he sent to on his old company. how can i clear or not export those caches emails. I used the following import command:
New-MailboxImportRequest -Mailbox user-FilePath \\SERVER01\PSTFiles\user.pst
Is there any parameter to clear those cached mailboxes
Thank you
