Email automatically deleted shared mailbox 365

We are using Office 365. I set up a shared mailbox using the instructions from http://o365info.com/setting-automatic-reply-office-365-using-shared-mailbox-part-22/. The instructions are a bit old; however I got it set up and added security a different way. The shared mailbox is sending all emails immediately to the deleted folder. There is no rules set up to do this. I tried adding all our users to the recipient list as well and this didn't change anything either. Any suggestions to look at to solve the emails being sent to the deleted folder.

The important question is did you make sure that no one else is accessing the shared mailbox at the same time? Either in Outlook or via mobile device? If so, the issue might be due to some sort of mailbox corruption, and you should raise this to MS. Or just export the mailbox content and create a new shared mailbox.

Double-check for any rules once you are logged in via OWA, just in case PowerShell didnt report them correctly. And just to double-check on what Sembee mentioned above, have you actually verified the AutomateProcessing setting? For a shared mailbox, it should be set to AutoUpdate and thus the value of DeleteNonCalendarItems should have no effect. If it is set to AutoAccept however (which should *not* be possible for a shared mailbox), this will explain the issue, as DeleteNonCalendarItems is set to True for all mailboxes. It is perfectly possible for this to happen if the mailbox was created as Room and later coverted to Shared.

Sounds like the folder might have a processing agent on it.
If it was setup as a resource mailbox then it would automatically delete all emails, because it is not expecting to get anything other than calendar information.

Without knowing exactly what you have done, it is hard to say much more.

Was the Shared Mailbox working correctly before you attempted to modify it?

No, this was a brand new set up for a shared mailbox. It's not linked to AD and I followed the directions in that page I linked. I can understand how it would delete the messages if it was set up as a resource room however I set it up in Shared Mailbox. (See Pic) Screen-Shot-04-03-15-at-01.16-PM.PNG

I have not set up a shared mailbox before and the other shared mailboxes I believe were migrated from an on premise server. If anything I may just have to delete the shared box and find different instructions that maybe more current.

It's not really clear to me if the messages are being deleted when SENT from the shared mailbox, or when RECEIVED there? In any case, check for any Inbox rules via:

Get-InboxRule -Mailbox shared@domain.com

Open in new window


You will need to connect PowerShell to Exchange Online in order to run this cmdlet: https://technet.microsoft.com/en-us/library/jj984289(v=exchg.150).aspx

Messages that are being received are deleted immediately. When I have a test email sent it will show up in the Inbox for a second and then sent directly to the deleted box.

When I run the command of Get-InboxRule -Mailbox shared@domain.com it displays nothing = no inbox rule. I ran others and verified that others had inbox rules and they did display.

Enable auditing on the mailbox and check the logs to see what's happening. Most likely one of the delegates is messing up. If you have configured the shared mailbox directly in Outlook or on any other device, make sure no rules there are interfering.

How do I set up auditing on a mailbox. When I set up the mailbox I did it through the Admin page of 365. I added the account to new setup of Outlook not an existing one as a sub account. When I sent the first test email from my account it didn't go to the deleted box. I then had others send test emails and that's when the emails started being deleted. I went back into my account and sent a message and that message got deleted. I at first thought that maybe the mailbox thought the others were spam that's why I sent another message from my account. I also tried to change the accepted recipients to our organization in the event there was something there that was effecting delivery. This was also not the case as messages still got sent to deleted box.

Follow the instructions in this article to enable auditing: https://technet.microsoft.com/en-us/library/dn879651.aspx

You should also try closing down Outlook and disconnecting any devices that have the shared mailbox (and/or its delegates configured) and try to reproduce the issue only running OWA. This will tell you with certainty if the issue is server-side or client side (the later one is a lot more likely).

I cannot access the shared mailbox through OWA. We are trying to free up licenses with shared mailboxes for some of our organization. Since it does not have a license OWA wont allow it to be opened. I can access the mailbox though Outlook with my credentials because it is shared. I enabled auditing on the mailbox but I do not know how to view the report. I followed the instructions on EAC but since it is a 365 organization, I do not believe the instructions pertain to the OWA administrators page. I tried the Compliance but there is not Audit area in it. We do not have an EAC since the servers are in the cloud.

You dont need a license for the shared mailbox, just login with one of the delegate accounts to OWA, click the profile pic, select Open another mailbox and select the shared one.

Auditing is enabled via PowerShell in EO, not via the EAC.

Logged in the way that you explained in OWA. Had someone send a test email and it showed up for a second and moved immediately to the deleted box.

I went ahead and deleted the shared mailbox. I am going to recreate a new one. The Autoupdate was set to AutoAccept in the calendar. I changed this but it didn't make a difference in receiving messages and deleting them automatically. This was a brand new creation and somehow 365 messed it up. Will accept your last response as correct solution.
Thanks for your help.

Also of note the new shared mailbox is working fine. I'm not sure how the first one got messed up. Only thing I did different in creating this one was to add delegates immediately rather than go into exchange properties once it was created.
Thanks again.
