Copied sent items of shared mailbox not recognized by 3rd party mail systems
Thank you for the link, it perfectly explains what's happening. I did open a support request and the answer is, that it's a feature. Here the response I got:
Thank you for your time today, as we discussed I have further tested this and found that the behavior is by design.
Basically since the option to save a copy of the sent items was added in the Portal the behavior changed, the shared mailbox is sending itself an email with the item that is then moved to the Sent items folder.
These emails have a form of trigger that moved them to the Sent items folder, for Office 365 mailboxes, for external addresses the might not recognize this trigger and this is why they are not moving them to the Sent items.
I will be checking if there is a way to block these emails from being sent to the forwarding address.
Probably the only way to block it, will be via a transport rule, but I'm not a big fan of that solution. Let's see what support will come up with.
Well, you can always leave feedback on this with your Microsoft TAM and even ask for a design change, but to be honest I don't find it that big of a deal.
We still have to problem and i link to this thread.
Anyone have found more information or a setting to change the configuration.
The problem on our site is, that it makes the Mailarchiv 3rd party Software fail, because it can't handle the mails.
If you are running only Outlook for Windows and don't use OWA at all, this add-in could help.
I haven't found a solution for this. We decided to live with it for now. We disabled the setting to keep a copy in the shared mailbox (with a external forward) for sent items.
