Script to generate office 365 groups created on last 30 days

Office 365, Scripts October 16, 2019 Leave a comment

By default it is enabled for users to create the office365 groups. There are few organizations where they do not need to restrict this group creation because these groups are heavily influenced on utilizing the office365 services Sharepoint,Yammer, Microsoft Teams, PowerBI , Outlook, Planner and Road Map which in turn might decline the office 365 user adoption rate.

The below script can be used to run in task scheduler on a monthly basis for reviewing the Office 365 groups which have been created in last 30 days and will email us the report.

Below is the sample output of the script which will provide us the below details.

Configure Exchange Online to reject emails that fail DMARC validation with organizations having policy of reject

DMARC, Office 365, Security October 8, 2019 Comments: 6

By default Office 365 DMARC validation for internet emails that fails for policy P=Reject will make the email to land in junk folder of the recipient mailbox. Microsoft 365 will treat DMARC policies of quarantine and reject in the same way, which means that if the sender’s DMARC policy is set to reject or quarantine, the emails that fail DMARC will be sent to the junk folder of the recipient mailbox which is by design as of now and can be found in the Microsoft Article.

Microsoft believes that the main agenda of doing this is to ensure that any legitimate emails which misses in DMARC alignment shouldn’t be lost and its better either to quarantine them or to get them delivered recipient’s junk mail folder. There are few cases wherein few organizations would still need the DMARC policy to be stringent due to their security regulations.

Microsoft validates DMARC and overrides the failure with a header value for a domain whose DMARC TXT record has a policy of p=reject oreject. Instead of deleting or rejecting the message, Office 365 marks the message as spam.

To test it further we are publishing SPF, DKIM and DMARC record for the domain ezcloudinfo.com as below:

Readiness and steps to Configure Direct Routing in Microsoft Teams

Microsoft Teams, Office 365, PSTN October 2, 2019 Comments: 2

Earlier to enable enterprise voice with calling plan on skype for business online we would need to install cloud connector locally on a virtual machines as a separate appliance which requires complex configuration for integrating with the certified session border controllers.

Now Microsoft have made it easier to configure them with direct routing where we do not need to deploy the cloud connector agent locally in the on-premise systems.

When paired with Microsoft Calling plans or direct routing with local ISP calling plan, they provide a full enterprise experience for office 365 users in Teams on a global scale. With Direct Routing we can Connect Existing Telephony Infrastructure to MS teams with the help of  local session border controllers. A SIP connection is created between the cloud call controllers and our local session border controllers.

In this article we will look at the options , readiness and steps  to Enable users for Direct Routing from the Microsoft office 365 perspective.

Readiness for Direct Routing:

Decide on Session Border Controller (Self or hosted SBC):

Session border controller connects Teams call to PSTN next hop or to the configured sip trunk with the local ISP. Here we have two options either to have own session border controllers on premise or to have this functionality hosted to a managed service provider who will host the session border controller for your organization to perform the SIP proxy and the PSTN routing for Microsoft Teams.

Make sure to select the supported session border controllers by Microsoft to configure direct routing in Microsoft Teams.

Figure out licenses based on deployment: Decide on media bypass Configuration

We need to figure out licenses on Microsoft office 365 to utilize the full enterprise functionality of Microsoft Teams.

Option1: Full Microsoft License

In this case no direct routing is required unless there is coexistence required with existing telephony system because we will be having the full calling plan with Microsoft and will utilize the Microsoft call controller, PSTN, Media controllers and Media processor.
