Hi guys,

I am hope you might be able to assist. 

I have users who access a shared mailbox (primary mailbox) as delegates with full permissions and send as permissions. They also have a nested mailbox which is their own personal mailbox. Mail sends from both mailboxes and when it behaves mail gets delivered to the sent item of the sender. But on a common recurrence mail sits in the Outbox of the delegate mailbox when sent from that mailbox. They can hit send/receive and it will force mail to send and also mail can delay for several minutes at times. This is also seen in OWA.

Removing the nested mailbox and adding it as a additional mailbox allows mail to flow without issue but mail sent from the additional mailbox gets placed in the sent items of the primary mailbox. Client would prefer the sent items to be kept separate (tried DelegateSentItemsStyle).

The exchange is a Exchange 2013 VM server and the client's use remote desktop services to access the platform. Also each Windows mail client is configured to use HTTP and cache mode is disabled for remote services. Last applied update was on the 08/2014.

Your help will be greatly appreciated.

PJ

Hi,

From your description, when you send a message from shared mailbox, the message is sitting in Outbox folder. I have seen some people have this issue, it is recommended to run Outlook using Cached mode as a workaround.

Hope this can be helpful to you.

Best regards,

You might also try to add this account (shared mailbox) within the mail profile, and check if you still have the issue.
