ADPro: Shared Exchange Mailbox Permissions after Cross Domain AD Migration (4180678)

table {mso-displayed-decimal-separator:"\."; mso-displayed-thousand-separator:"\,";}tr {mso-height-source:auto;}col {mso-width-source:auto;}td {padding-top:1px; padding-right:1px; padding-left:1px; mso-ignore:padding; color:black; font-size:11.0pt; font-weight:400; font-style:normal; text-decoration:none; font-family:Calibri, sans-serif; mso-font-charset:0; text-align:general; vertical-align:bottom; border:none; white-space:nowrap; mso-rotate:0;}.xl19 {text-align:left; vertical-align:middle; white-space:normal;}We are performing a domain to domain migration using ADM with Exchange mailboxes in a resource forest.  We can re-link the mailboxes via a script, I'm assuming since the share mailbox permissions are set via the disabled user account in the Exchange resource forest that they users wont have any issues accessing them after migration?  Is my logic correct?
