Exchange Online Launches Expiring Domain Insight (and Causes a Little Confusion)

Exchange Online has a new domain expiring soon alert, which means that a mail flow insight checks for soon-to-expire domains in the set of accepted domains for a tenant.

Five years ago, you could argue the same case and companies with bad network connectivity to the internet or specific security requirements were happy to stay on-premises. Now?

At the Ignite 2021 event, Microsoft announced that Teams will have multi-geo capabilities later this year. The same $2/user/month uplift as used for other multi-geo workloads applies to Teams.

Microsoft Wants to Talk About Group Sprawl (Finally)

Nearly seven years after the introduction of Office 365 Groups, Microsoft has finally admitted that tenants might just have a problem with "group sprawl." In other words, tenants have too many underused or unused groups because the groups have been created without oversight and not managed thereafter.
