I currently inherited a installation running its own server for hosting (Wordpress/Magento) and also e-mail. E-Mails are used within the organization via Outlook (non 365) and imap.

The plan is to switch to Office 365 (as we will also use Dynamics 365 CRM in the future) and I'd like to switch over from the self-hosted emails to using Office 365.

I am wondering now, what is the better solution.

I am a Security Engineer at my organization and I'm looking for ways to automate the reporting process for suspicious emails.

We are using Terranova Security Awareness for Phish email reporting, and I receive these reported emails in my mailbox. These email reports contain the header details of the reported email, and the reported email itself as an .eml file.

I also have access to Microsoft 365 Sec ...

I use Postfix v3.1.15 to relay emails from my own internal systems (alerting, backup reports etc) to smtp.office365.com to be delivered to my O365 mailbox.

I've been using Postfix installed on Debian 9 for this for a couple of years. However I am receiving emails from Microsoft informing me of depreciation of TLS1.0 and TLS1.1 soon and to use TLS1.2 going forward as they have detected I am still  ...

We r using Microsoft 365. I am trying to create Import Jobs in Information governance of Microsoft 365 compliance in Exchange Online. I am getting the message "To create import jobs, you must be assigned the Mailbox Import Export role in Exchange Online. After this role is assigned, it might take up to 24 hours before you can start creating jobs."

We use o365/Exchange Online. All our SPF and DKIM configs are good for our domain (including 3rd party senders).

Say we have a partner who has domain XYZ123.com (with their own mail servers) and they want us to be able to send as them (from our o365 Exchange).

So this is the opposite of what I've done in DKIM in the past, and can find no info on doing it in reverse.

How do I generate/obtain the 3rd-par ...

We recently updated to Windows 10 from Windows Server 2012, and we are using O365. Suddenly users are seeing mixed profile pictures in Outlook, in both the Toast Notifications and the emails themselves. From one email to the next, it could be a different picture for the same user. It is both internal and external emails. None of our users have locally saved contacts that could be using photos.

Is it possible to configure a dynamic distribution group to contain all direct reports of some person, plus all their direct reports recursively?

Verbose Info

To get the direct reports only I believe we'd just run:

Set-DynamicDistributionGroup -Identity 'SomeManagersDirectReports' `
    -RecipientFilter "((RecipientType -eq 'UserMailbox') -and (Manager -eq 'CN=SomeManager,OU=Users,DC=domain,DC=example,DC= ...

TLDR: Outlook.com appear to be junking all our emails from new VPS - nothing has an effect so questioning if IP address range reputation is the issue.

We used to host all our websites (five) and email on a single VPS. Due to email problems that we were unable to resolve we obtained another server from a different company (Hostinger) to host our email.

Everything has been set up ok as far as we know - S ...

I did run into the situation that I lost all my public folder permissions which were assigned via groups.

Before the migration started from our MSEX2016 server to Office 365, all the permissions got exported to a XML file, what I think (described on this Microsoft page) happened with the following command:

Get-PublicFolder -Recurse -ResultSize Unlimited | Get-PublicFolderClientPermission | Select-Object ...

I have an existing O365 tenant with a custom domain name.

I also have a couple of VM's running in Azure and for all sorts of reasons I would like to add Azure Active Directory Domain Services.

Where it comes to chosing the domain name, the Azure Portal UI is defaulting to the existing O365 custom domain name.

I am a little unlcear as to whether I should choose this option, or change it to some other do ...

We installed a new Exchange 2016 server and migrated all the mailboxes from the Exchange 2010 server to it. Then we migrated all the mailboxes and public folders from MSEX2016 to Office 365, and we demoted and shut down the MSEX2010. The local AD gets synchronized with Azure AD by the Azure AD Connector on one of our local servers.

This worked for a couple of weeks without problems. All the clien ...

I know that there are naming policy settings available for Office 365 groups applied to the mailbox addresses. But is there a way to enforce a naming policy only on the group mailbox rather than everywhere?

We want to create a "NewProject" group and the mailbox automatically named "newproject.team@our.org".

I've been asked to see if we can get an idea of how many external mails we receive, and what external domains are the most "active".

Basically what's wanted is a report detailing how many mails we receive from external domains under a specified time period: I'm thinking something along these lines is what's being asked.

I've got a 3rd party who host a system for us, it has a function to send a small number of emails for us, less than 100 a day, so we simply supplied an Office365 user to them which has been working for ages.

Last night this stopped working. The interface I can see is simply returning Message could not be sent. Mailer Error: SMTP connect() failed. (PHPMail)

I was thinking of using Tags assigned to Users in a MS Teams (on Office365) Team for some reporting related things and query them in some PowerShell scripts. Is there a way to get this information?

I was thinking something along the lines of the Get-TeamUser command. But I can't really find any PowerShell commands that are able to do that in any way.

I am about to move users to Office 365 email from an old hosted smtp/pop system.

The domain is configured for 365 with the exception of the mx record.

I would like to create the accounts in 365 ahead of the migration and gradually move users over without impacting their current mailboxes.

For the first two test users I have forwarded the old mailbox to the new mailbox using the onmicrosoft.com alias.  ...

So, one of the companies I work with encountered some chaos in their hybrid MS365 / on-prem deployment.

There is a distribution list (we'll call it distlist1@example.com) which is present on both the on prem and MS365 side of management consoles. However, while on-prem Exchange control panel shows distlist1 as accepting mail from both inside and outside the organization, MS365 has decided to ignore  ...

There is a feature in Exchange Online which blocks users from being able to send email when they send too many emails in a time period. It usually triggers either when a user sends a load of emails via Mail Merge or when their account gets compromised and it's used to send a load of spam.

You can view which accounts have been blocked from sending either by going to the Restricted Users page in the Defen ...

Microsoft has made anonymous display of user-names as default in Office 365 and also enforced it from August 31, 2021. I found a way to overcome it from Admin Portal. https://docs.microsoft.com/en-us/office365/troubleshoot/miscellaneous/reports-show-anonymous-user-name

I am curious to know if there are any major gotchas with setting up a 'reverse hybrid' 365 deployment, where all mail flow is already in the cloud with on-prem ad sync already enabled and simply adding on-prem exchange to the mix. I have found surprisingly little discussion about this online and I was hoping to find out if there are any major concerns with doing this sort of thing.

I am receiving the following alert for an internal address:

Potentially compromised account. Anomalous sending patterns were detected resulting in the user being restricted from sending mail

Ironically, it's my alerts@ address. It's sending multiple external emails to cell phone addresses (@vtext.com, etc).

I have unblocked the address a few times following the directions here, but it keeps getting fla ...

I have set up some phishing/malware mail-flow rules that will forward emails to me for review based on attachments or a list of domains. I can then choose to accept or reject the message. It seems to work well. The problem I'm having is that this weekend, some were automatically rejected because I didn't respond in time.

How do I change this time to "auto reject"?

We have 2 Exchange Server 2016. I want to check it if I am using Full Hybrid and / or minimal hybrid in our environment. What should I understand from the following output?

We have a few legacy Windows 7 machines in our environment (long story) that have old versions of MS Office. While MS 365 is no longer supported on Windows 7, MS 365 Apps at version 2002 will at least continue receiving security updates until 2023.
