Hello, 

Yes, this setup is possible in Odoo 19.sh, but Microsoft 365 shared mailboxes usually require additional configuration compared to standard user mailboxes.

The recommended approach is:

• Configure each shared mailbox properly in Microsoft 365 with delegated permissions
• Use Microsoft Azure OAuth authentication instead of basic SMTP/IMAP authentication
• Create separate incoming/outgoing mail servers or aliases in Odoo for departments like sales@, finance@, logistics@, etc.
• Configure Odoo mail aliases and routing rules so emails automatically create CRM leads, invoices, helpdesk tickets, etc.

In many cases, the issue comes from Azure app permissions or shared mailbox access rights rather than Odoo itself.

Hope this works for you! If you need any help implementing this or want a more optimized approach, feel free to reach out for further discussion.
