Shared Mailboxes - When replying to a message that is not in the inbox

Iron Contributor

There is an option in Outlook to save the reply in the same folder when you are replying to a message that is not in the Inbox:

However, it doesn't seem to work for shared mailboxes. Is there a way to make it work for shared mailboxes?


We are using Office 365 semi-annual channel so everyone has reasonably up-to-date versions.

Hi @John Twohig, no you can't do that in Outlook natively.

It's possible to create a VBA script or (better) an add-in to implement this functionality though.

For this (and many other) feature to work, you need to add the shared mailbox as additional account in Outlook (via File > Add account) as opposed to adding it as additional mailbox/automapped.

Adding the account was the first thing I tried but it didn't work. After I saw your reply, I removed the permission and then added it with


Add-MailboxPermission -Identity -User -AccessRights FullAccess -AutoMapping $false


to get rid of automapping then added the account and it works.
