Hello,
We have Office 365 running with several shared mailboxes. We configured the value DelegateSendItemsStyle so when you send an email it will be placed inside the shared mailbox send item folder. (See KB:http://support.microsoft.com/kb/2181579). So far so good.
When we send directly from an Office application like Excel (File -> Share -> E-mail -> Send as Attachment), in the new email window we change the From field to a shared mailbox, type our text and send the mail. Now the file will be placed inside the users send items folder.
Somehow when we mail directly from Word/Excel the DelegateSendItemsStyle gets overruled and ignored. When we change the shared mailbox to a payed one with a license, add the box as a second Exchange account and send the mail then, everything is ok and the mail will be placed inside the shared mailbox send items folder. As you might understand, with 25 shared mailboxes it is a waste of money to license them all.
I contacted Microsoft Office 365 support, and this is outside of their support scope.
Any ideas how we can fix this?
Thanks in advance.
Kind regards,
Max
