Managing Office 365 Group Membership with PowerShell

A reader wants the benefits of dynamic Office 365 groups without having to pay for Azure AD premium licenses. It’s relatively straightforward to maintain the membership of a group with PowerShell.

Handling Calendar Appointments for IMAP4 Clients

Despite the age of the protocols, you can cheerfully connect a wide range of IMAP4 and POP3 clients to Exchange Online. If you do, you might need to consider how to handle calendar appointments, and if you want to use iCAL, you’ll need to make some adjustments with PowerShell.

Excluding Inactive Mailboxes from Org-Wide Retention Holds

Exchange Online supports inactive mailboxes as a way to keep mailbox data online after Office 365 accounts are removed. Inactive mailboxes are available as long as a hold exists on them.

CISA Report Only Scratches Surface of Securing Office 365

The CISA report titled “Microsoft Office 365 Security Observations” makes five recommendations to improve security of an Office 365 tenant.

In fact, the worst thing is that consultants brought in to help organizations didn’t seem to have much expertise in securing Office 365.

Office 365 Groups Naming Policy Now Configurable in Azure Active Directory Portal
