Delegated Mailbox Access Issues
I have few mailboxes which are used by multiple staff members. Currently these mailboxes are added as separate accounts in Outlook desktop of users by using the passwords and MFA of these mailboxes. This approach is very often causing issues when the passwords of these mailboxes expire or the MFA is required. To avoid this, I have started providing users delegated mailbox access by giving "read and manage" and "send-as" permissions. This approach is working and providing the access to users but one user stopped receiving emails with an error that the mail store is full because delegated access starts downloading the data of the mailbox to the user's personal OST file. Is it possible to have the data of delegated mailbox downloaded to a separate OST? How can this be achieved? I want to have the mailbox appear as separate account in the Account Settings in Outlook as this will allow all the other functionality like separate mailbox rules etc.
