Dynamic Distribution Group with no Disabled Accounts
Hi I'm trying to build a few Dynamic Distribution Lists in Exchange Online and want to only include Active Users (i.e., users that are marked "Active" in Azure AD). I've tried using the UserAccountControl attribute (-eq 514 or -ne 514 - both are returning the same results, which is strange), but it still includes user accounts that are disabled. This is how my recipient filter looks like: RecipientType -eq 'UserMailbox' -and UserAccountControl -ne 514 What's the best way to achieve this in Exchange Online? Thanks Taranjeet Singh
DMARC rejection after Exchange upgrade
I'm having problems with inbound emails getting bounced as Undeliverable due to DMARC rejection. For many years I've had my email come through Fasthosts / Livemail to my own domain (qts.org.uk) with catch-all forwarding set to forward everything to my GMail account. Just recently Fasthosts have upgraded their servers to Exchange and I've started getting DMARC rejections from GMail which start Diagnostic information for administrators: Generating server: exchange2019.livemail.co.uk Total retry attempts: 1 (my gmail email address) t1-hex-xprelay.gem.livemail.co.uk Remote Server returned '550 5.7.26 Message rejected by DMARC policy by gmail.com. Please use your own email address as the sender, instead of (sender's email address). [MSG0009]' Which bounce from Fasthosts / Livemail back to my GMail address. My own domain has SPF, DMARC, and DKIM configured I've done a little digging and it appears to only affect senders from originating domains with DMARC set to reject. So either GMail has coincidentally become much more strict (possible) or Fasthosts are somehow failing to forward emails fully transparently. I have spoken to Fasthosts and logged the issue with them and was not impressed so I hope the experts here can offer a solution I can forward to them.Office 365 Message Attribution
When a message arrives at Office 365, one of the first things we need to do is figure out which organization it belongs to. At first, this sounds simple – just look at the recipient, right? Well, it is more complicated than that, because of Hybrid and complex routing scenarios.
Both The Owner & I Have Requested Assistance Regarding A Domain Transfer But Have Had No Updates.
Both the owner & I have requested assistance in regards to a domain transfer. There is a phantom account holding our already verified domain.... We have lost a full month of service for over 150 users due to the errors on Microsoft's side. Please answer one of our cases so that we can finish up the migration. We were not anticipating such a difficult experience. One of the cases is registered to the associated email. Thanks. Microsoft 365 Migrations Microsoft Entrasinged pdf files get blocked when user is sending from shared mailbox
Hi, in exchange environment, I have my email account and also I have shared mailbox linked. I can sent the singed pdf file attached to email from my email but when I send it from shared mailbox, I get the following message everytime: "From: email address removed for privacy reasons <email address removed for privacy reasons> Subject: Executable File Violation You attempted to send a message that contained an executable file. Our company policy prohibits the sending of executable files via email. The message was not delivered." We have symantec spam filter in organization, which I think is causing that error, or it can be exchange policy which is more restrictive (on default or someone configured it so), I wonder if it is possible to address this issue and let the singed pdf flow from shared mailbox. What can I do to fix it? From where should I fix it - exchange management / shared mailbox policies or where do I find that options to configure correctly? Thanks George
