| Name : Find_MailboxPermissons_Dependencies.ps1 | |
| Author: nivleshc@yahoo.com | |
| SCRIPT IS PROVIDED 'AS IS' WITHOUT ANY WARRANTY OF ANY KIND. | |
| Before running any script, please read the entire script to ensure there is nothing in it that will harm your environment | |
| Requirements: | |
| - Run Roman Zarkar's Export-MailboxPermissions.ps1 (this script is part of the bundle at https://gallery.technet.microsoft.com/scriptcenter/Migrate-Mailbox-Permissions-2f262f8b) | |
| and provide locations of the output files MailboxAccess.csv, MailboxFolderDelegate.csv, MaiboxSendAs.csv, MailboxSendOnBehalf.csv | |
| - Office365 Mailboxes Details | |
| Run the following command against your Office 365 environment to get details of all your Office 365 mailboxes | |
| Get-Mailbox -ResultSize unlimited | Select DisplayName,UserPrincipalName,EmailAddresses,WindowsEmailAddress,RecipientTypeDetails | Export-Csv -NoTypeInformation -Path O365_Mbx_Details.csv | |
| If you don't have any mailboxes in Office 365, then just create a file with the following header | |
| "DisplayName","UserPrincipalName","EmailAddresses","WindowsEmailAddress","RecipientTypeDetails" | |
| - OnPrem Mailboxes Details | |
| Run a script to get the following information for all your on-premises mailboxes and put it into a csv file | |
| DisplayName,UserPrincipalName,PrimarySmtpAddress,RecipientTypeDetails,Department,Title,Office,State,OrganizationalUnit | |

unfortunately, Roman Zarkar's Export-MailboxPermissions.ps1 (https://gallery.technet.microsoft.com/scriptcenter/Migrate-Mailbox-Permissions-2f262f8b) doesn't seem to be available any longer. would it be possible to provide an updated location or share this bundle (scripts) in here?
Same comment as Bitbull06. Source script is no where to be found.

Hey - so is there anyway to create this dependency - we are doing a tenant to tenant migration (one domain to another).
I understand the permissions will change, but I am just looking for a way to capture and document them in one place
