Email Showing as Quarantined in a Message Trace, but Not Showing up in MS Defender
A customer of ours was waiting on an email to arrive and to help figure out where the email was or if it was sent yet we ran a message trace. The message trace showed that the email was sent to quarantine. With this information in mind, I went to MS Defender > Email & collaboration > Review > Quarantine but could not find the message. I modified some of the filters and could not get the quarantined message to appear. I triple checked the filters I created and made sure the information was correct. I also removed all filters and looked for the time period the email came in, but could not find it. Not sure if this is related, but this email had a significant delay likely coming from the sender. Any thoughts or ideas? Or anything that I am missing?
Mailbox for Service Account (exchange online)
Hi Our organisation isn't ready to move to Exchange Online yet, though we have Office 365 e3 licencing. I need to create a service account that can send emails via Outlook 365 for use In Power Automate. The documentation I have seen for adding a mailbox to an existing AAD user requires assigning an exchange licence to the account via the licence portal. I can't see any such licences though we do have e3 licencing which are visible that I assume covers this? Unfortunately the admin who did the original configuration has moved on and I don't have a global admin role so have to go through a support team that can't help me with my lack of knowledge in the area! Any advice would be very much appreciated as what ( i think) should be a simple task has taken a lot of time to try and get to the bottom of! Thanks, Dale.
Emails from Azure Communication Services (ACS) are treated as external emails
When using Azure Communication Services (ACS) Email, messages are delivered to Microsoft 365 as external mail, even if the system sending them belongs to my own organization. This behavior can be expected because ACS sends emails from Microsoft’s cloud infrastructure rather than directly from my tenant. As a result, Distribution Groups (DG), Dynamic Distribution Groups (DDG), or Mail-enabled Security Groups (SG) that are configured to accept messages only from internal senders will reject these emails. The common workaround is to enable “Allow external senders” on the group. However, we don't want to open the group to the entire internet. Does anyone else have the same experience? What is the best solution, exchange transport rules? Thanks!Exchange online - track deleted mail
I am 365 admin and see quite often people rapport "all my mails are in deleted post - and I have done nothing" or similar What is the best practice to investigate that. I know in powershell I have made some auditsearches, where it rapports like softdelete, hardelete etc - but is there any more specific way proving that the user actually did in on his own ? - I know with retention policies it is hard delete - but just wondering what the best practice is like to prove to the user that this is the user. Just write that it is soft deleted and means user have done it, often the user think is not understandable
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
Exchange 2010 to Microsoft 365 Migration – Recommended Approach and Tools
I’m looking for guidance on migrating Exchange 2010 (on-premises) to Microsoft 365 / Office 365. Is a direct migration from Exchange 2010 supported, or is an intermediate hop (such as upgrading Exchange or setting up a hybrid configuration) required? Additionally, could you please recommend any reliable tools that can help with this migration? I also have a few PST files that need to be migrated as part of the process. I’d appreciate insights on best practices, common challenges, and lessons learned from real-world migrations. Thanks in advance for your help.
Feedback to users who report phishing
Hi, is it possible to create a power automate flow to find submissions from users and as soon as MS has added a verdict to a submission as real phish send a notification back to the user who has reported it? Trying to figure out what is needed for such integration and build a flow but I am stuck. Anyone who has built that and like to share learning?
Linking cloud only shared mailbox with onpremise object
Hi all, We currently have a cloud only shared mailbox in exchange online that we need to exist in onprem exchange for a smtp relay that is setup in a hybrid config.
