I received a request to grant access to a deleted user's mailbox.
We are running a hybrid Exchange environment, Exchange 2019 (on-premises) and Exchange Online.
Do I need to connect the mailbox to another user (or create a new temporary user) and then grant read permissions to the mailbox.
I'm confused on process.
Any and all help is appreciated.

Hi @BHBDAA,
to authorize permissions for a mailbox of a deleted user within a hybrid Exchange environment (Exchange 2019 on-premises and Exchange Online), you can follow these steps:
Reconnect the deleted mailbox:
Reestablish a connection for the deleted mailbox by associating it with another existing user or creating a temporary user. This is essential as permissions can only be assigned to active mailboxes.

Grant permissions:
Once the mailbox is linked to a user account, proceed to assign permissions. The following steps illustrate how to achieve this in Exchange Server:
Add-MailboxPermission -Identity "UserMailbox" -User "DelegateUser" -AccessRights FullAccess -InheritanceType All
Ensure to replace "UserMailbox" with the target mailbox and "DelegateUser" with the designated user.
