Please confirm:

  • I have searched existing feature requests (open and closed) and found no duplicates.
  • **me or my organization is currently an active sponsor of the product at the $99,- level.

Problem Statement

When creating Shared Mailboxes, the default setting is to store sent email in the "Sent Items" belonging to delegated users. It's quite a common need to change this so that sent email is saved in the "Sent Items" belonging to the Shared Mailbox itself.

Currently, I can't see a way to set this in CIPP, so we have to use an alternative product to set this. I propose adding the ability into CIPP, to set the location of "Sent Items" - at the point of creating a shared mailbox, and when editing existing shared mailboxes. Some other users may want this feature extending to all user mailboxes too - not sure if that's possible or not.

The screenshot below shows the location of this setting in the Microsoft 365 Admin Center GUI:

We are a paying customer/sponsor of CIPP.

Benefits for MSPs

Part of the routine workflow when creating shared mailboxes, we have to manually set the location of Sent Items. It would save time if we could do all this through CIPP, rather than having to switch to a different product.

Value or Importance

It's not critical, but a "nice-to-have" feature. It would save time. Competitor products already have this feature.

PowerShell Commands (Optional)

I'm not a PowerShell coder, but I found the following which may be helpful:

Set-Mailbox -MessageCopyForSentAsEnabled $True
Set-Mailbox -MessageCopyForSendOnBehalfEnabled $True

Already exists. Use the standard "set delegated mailbox sent items"

Ah sorry @KelvinTegelaar , I didn't realise it was already implemented. I can't see it in our CIPP instance, it may be a permissions issue at our end then. I'll look into it. Thank you.

Just asking for a friend ;) What if it's not the STANDARD we want to apply, and that the scheduler might take too long to implement, and we want to be able to apply these on creation of the shared mailbox? I think this was maybe the direction of the original request? i.e there are times when a one-size fits all is not desired.

yes @patrickhelm721 , what you have stated, is what I meant.

To be honest, I didn't really know what the "STANDARDs" were, but I've just explored, and I get it now (I'm new to CIPP). But yes, it would be nice to have the ability to set/change this on a per mailbox basis, as I don't think you can do that in CIPP (just set it on an individual mailbox)? This is a standard configuration feature in other competing products; I'd prefer to do this in CIPP! :)
