On-prem shared mailbox access in hybrid Environment
Migrating user's mailboxes from exchange 2016 on-prem to exchange Online in Hybrid configuration.
What is the best approach regarding the shared-mailbox present on-prem ?
Users migrated to exchange online lost access to the shared mailbox, outlook removed the shared mailbox from profile, until the shared mailbox is not migrated as well.
Is there a way to have the migrated users still able to access the on-prem shared mailbox ?
thanks

There is, but it depends on the permissions. Full access is supported cross-premises, delegate/folder-level permissions require additional steps. Automapping is not supported, which is why the mailbox was removed from Outlook.
It's usually best to move them (together with the corresponding user mailboxes) to ExO. See for example: https://learn.microsoft.com/en-us/exchange/permissions#mailbox-permissions-and-capabilities-not-supported-in-hybrid-environments
