It has been a while since we blogged about the ability to control the behavior of Sent Items for shared mailboxes when users either send as or on behalf of shared mailboxes. Today, we are glad to share with you that this feature is currently rolling out for User mailboxes also! What does that mean in real life? Let’s say you have the following scenario:

  • Mary is a delegator/manager on the team
  • Rob is a delegate on Mary’s mailbox; Rob has Send As or Send on behalf of rights on Mary’s mailbox.
  • When Rob sends an email as Mary, the email will be only in Rob’s Sent Items folder
With this feature enabled on Mary’s mailbox, Exchange will copy the message that Rob sends as Mary to the Sent Items folder in Mary’s mailbox. In other words, both Rob and Mary will have the message in their Sent Items folders. We have heard this request more than once, and now we are rolling it out to an Exchange Online mailbox near you! The configuration and behavior of the feature is the same as for the shared mailbox.

Note: If the user has used the Outlook 2013 feature to change the folder that Sent Items are saved to, the messages will be copied to that folder instead of the user’s Sent Items folder. Users can reconfigure this by clicking the Save Sent Items To button on the Email Options tab.

Enable message copySent On Behalf of the delegatorFor emails Sent On Behalf of the delegator:

Set-Mailbox <delegator mailbox name> -MessageCopyForSendOnBehalfEnabled $true

Disable message copySent On Behalf of the delegatorFor emails Sent On Behalf of the delegator:

Set-Mailbox <delegator mailbox name> -MessageCopyForSendOnBehalfEnabled $false

To... For messages... Use this command...
Enable message copy Sent As the delegator

Set-Mailbox <delegator mailbox name> -MessageCopyForSentAsEnabled $true

Disable message copy Sent As the delegator

Set-Mailbox <delegator mailbox name> -MessageCopyForSentAsEnabled $false

Note, you can use the Office 365 Portal to configure this for shared mailboxes, but to configure user mailboxes, you'll need to use PowerShell (the team would like to hear if you feel it should be in the Portal too!). For various other details of behavior please see the shared mailbox post. Next question that some might have is: What about on-premises?

Update 4/17/2016: As it stands right now, we plan to release this feature as a part of the Exchange 2016 CU6 release.

Enjoy! The Calendaring Team

Any plans to roll-out the same feature in a future CU for On-Prem or Hybrid customers ?
Not applicable
As noted in the post, stay tuned!

+1 to Benoit. Looking forward to see this feature appear in one of the upcoming CUs.
Not applicable
This feature will be included in Cumulative Update 6.

Good feature and +1 for On-Prem

https://support.microsoft.com/en-us/help/3193138/update-to-apply-messagecopyforsentasenabled-to-any-type-of-mailbox-in-exchange-server-2016

This update describes a change in which the MessageCopyForSentAsEnabled and MessageCopyForSendOnBehalfEnabled settings to save sent messages into a different mailbox can be applied to any type of mailbox with the Set-Mailbox cmdlet, not just shared mailboxes. This feature keeps a copy of the email in the Sent Items folder of the alternative mailbox.

Not applicable
So... yeah, about that KB article...

I just filed a request to get the article pulled. It is confusing as to why this happened but no... the article is not correct as written and the feature - as you expect it (for all user mailboxes on-prem) did not ship in CU4. It's... complicated. I'll update the blog post when I have a better idea of when we will ship on prem. Sorry about the confusion!

Not applicable
Cool! Now do the same for Deleted Items!
Not applicable
+1

+1 for deleted items!
Not applicable
Would love to see this for deleted items as well indeed :)
Not applicable
I wondered some weeks ago why i can set this for user mailboxes and it does not work. for shared mailboxes it worked. now it seems to work also for user mailboxes. Great!

Where was this announced? I didn't got a message from the Message Center in O365.

Not applicable
Would definitely like to see this in on-prem, as well. Having it in Exchange 2013 would be nice.
Not applicable
+1 for the Exchange 2013 On-Prem
Not applicable
Thanks for post, would be very nice if it can be added from Portal and OWA which can him self apply these settings. Thank you for update
Not applicable
Thanks for this. I, too, am really looking for this to come to on-premises.
Not applicable
3 questions:

1. Will this behaviour be applicable to Deleted Items hopefully in the not too distant future?

2. Is there a way we can globally apply this setting so that anyone who has Delegate Access to another mailbox, automatically has this setting enabled?

3. Will this work if access to the shared mailbox is granted via security group memberships as opposed to individual user accounts?

Not applicable
How about to change the default settings for existing and future new mailboxes so I don't need to change the default behaviour?
Not applicable
Hi.

This topic would be nice, but the mailbox owner is really affected if use Outlook for mobile, owa, ActiveSync or Outlook for mac. At least for our tests, not sure if "Mary" in your scenario is happy or not.

Because for each mail owner sends receive inmediately a warning with this message

"The attached message was sent a user who has Send-As or Send-On-Behalf-Of rights for this mailbox. Usually, it would appear in Sent Items, but your service is currently being upgraded. The message will be saved to your Sent Items folder after the upgrade."

Regards

Great Feature and looking same for On-premise Exchange server versions too..
Not applicable
It would be nice if this "feature" (what was already existent on Exchange 2010 SP3) would also be available for Exchange 2013. Also a possibility to configure ActiveSync read receipt for Exchange 2013 (which is also only available for Ex2016) would be nice.
Not applicable
+1 on adding the feature to the portal for all mailbox types.

+1 on adding the same for deleted items

+1 globally apply this setting so that anyone who has Delegate Access to another mailbox, automatically has this setting enabled

Not applicable
This is great, for things like this I wish there was a "powershell on the web" that O365 admins can just leverage to run these sort of commands.
Not applicable
Has anyone tried it? It does not seem to work for us.
Not applicable
NIce Feature! I have a sigh of relief :) I was been bombarded by VIP users with this issue.
Not applicable
I read this article looking for a statement on what the default behavior would be for newly created mailboxes. Guess I'll find out soon enough by testing, and I can certainly include this in my script for creating new users, but it would have been nice to see the question addressed here. Thank you for developing the feature in any case.
