Shared mailbox: Use send-as, not send on behalf from Outlook 2016
Hello, We have a lot of shared mailboxes. For every shared mailbox, we create a specific security group that contains the members who should have access to that particular shared mailbox. We give full mailbox permissions and send-as permissions for that particular security group onto the shared mailbox. For example, security group A has full mailbox access and send-as permissions onto shared mailbox A. By adding users to security group A, they have full access to the shared mailbox. We create every new shared mailbox/security group combo using Powershell. That has been working flawlessly for the last years. However, for a recent new shared mailbox/security group combination, when a user that's member of the related security group wants to send an e-mail from the shared mailbox (by changing the from field in Outlook and selecting the shared mailbox from the global address list), Outlook tries to send every time 'send-on behalf'. This only happens for that newly created mailbox. I compared the output of Get-Mailbox and Get-RecipientPermission for the new problem shared mailbox and an older shared mailbox (which enable users to send mail send-as from outlook just fine) but I couldn't find any differences. For your information, that's the error we get back immediately after trying to do a send-as for the new shared mailbox: Your message did not reach some or all of the intended recipients. Subject: Test from Outlook Sent: 23/11/2017 9:27 The following recipient(s) cannot be reached: name of sending user on 23/11/2017 9:27 This message could not be sent. Try sending the message again later, or contact your network administrator. You do not have the permission to send the message on behalf of the specified user. Error is [0x80070005-0x0004dc-0x000524]. Why does Outlook always tries to do a send on behalf (what we don't want) where else for other shared mailboxes, send-as works fine? Using send-as from OWA however works just fine for the newest shared mailbox. It only seems a problem related to Outlook (tested on multiple clients that have access to the shared mailbox) and that particular new shared mailbox. Thanks in advance.

"NeedsApproval"
Hi All, So I have been migrating mailboxes from onprem to O365 in the hybrid config with no issues. Today I have two migration batch jobs that state "NeedsApproval", but everything migrated. Kind of confused as i don't see a way to "approve" the jobs and I don't see any issues. Any ideas?

does not designate permitted sender hosts
Hi Everyone I am hoping someone can assist me with the following issue. I have SPF and DKIM configured on my domain, which appear to be setup correctly but when I examine the message header of an email I sent I see the following entry "None (protection.outlook.com: za.cfao.com does not designate permitted sender hosts)" Just to add I am using Exclaimer for signature management. Please can someone examine the header below and advised if I configured something incorrectly.

Configuring Delegate access via PowerShell.
Is the following window configurable at all via PowerShell? lots of Googling brings up various options and none seem to work. (this is in relation to the box below specifically) Things I've noted: Delegates set here are "ResourceDelegates" for the Get-CalendarProcessing output, but you can't use Set-CalendarProcessing as it only works on resource mailboxes (Error : "ResourceDelegates can only be enabled on resource mailboxes.") Under Get-MailboxFolderPermission user:\calendar you can also see the delegates setup, and with a SharingPermissionFlags of "Delegate, CanViewPrivateItems" (if set when adding them via the GUI above) but using Set-MailboxFolderPermission or Add-MailboxFolderPermission you can't seem to set those flags. Anyone had any ideas? hooking into EWS perhaps?

AutoMapping Shared Mailbox based on security group
Hi, We were under the impression that once on exch 2016 we would be able to use mail enabled security groups for shared mailboxes -- and (this is the important part) still be able to have the automapping feature work (ie. all members of the security group would see the share mailbox in their outlook profile) Testing has shown this not to be the case, and now I am seeing this: https://technet.microsoft.com/en-us/library/jj919240(v=exchg.160).aspx which is also suggesting that shared mailboxes cannot automap on a security group. Can anyone say for sure one way or the other - is this on the radar to start working eventually? I know people have been talking about this since exch 2010.

I created an Exchange Online mailbox but it doesn't appear in on-prem EAC. How do I fix?
I discovered this issue because the CRM for Outlook add-in (the modern one, not the full client) complained that a new user was not logging in with the same email address and is Dynamics 365. I couldn't confirm this no matter where I looked so I checked his Office 365 user and, sure enough, his default SMTP address is username@tenant.onmicrosoft.com rather than username@ourdomain.com. I also notice that he doesn't have any of the other standard aliases that other users have. The key difference with him is that he's the first new user I created where I didn't first make an on-prem mailbox and migrate it up. Not knowing any better, I thought, "Why go through that step? I'll just create the mailbox in the cloud." At this point I'm a bit unsure what step to take next. When I look at EAC on-prem I don't see his user there at all. All other users either have a mailbox type of "User" or "Office 365". Should I migrate him to on-prem then back?
