Dear all,
I have users with 2nd mailbox attached to their Outlook, after movement the mailboxes to Exchange 2013 they're no longer able to send any e-mails from the 2nd mailbox
And they also get this ERROR:0x80070005-00000000-00000000
If I attach the same mailbox to my Outlook, I have no problems with sending e-mails.
Does anyone know what might that be?
Thank you
