If you are experiencing problems with an Office 365 service, the native option is to check Microsoft’s Service Health Dashboard (SHD) in your Microsoft 365 Admin Center to determine whether this is a known issue with a resolution in progress before you call support or spend valuable time troubleshooting. However, the information that is provided through the SHD is only of limited use, as it focuses primarily on the overall service health instead of tenant-specific or user-specific problems.
M365 - Exchange Online Center
ENow Software's Microsoft Exchange Online blog built by Microsoft MVPs for IT/Sys Admins.
Two organizations each have Microsoft 365 tenants and they want to work together on several projects – some of which run for a limited time and some of which are ongoing. How can these organizations enable their people and teams to collaborate more effectively and productively across their different tenants? Add on top of this, how can this be done in a secure and compliant manner? This article describes several key collaboration options that administrators at each organization can consider as shared goals.
If you've ever participated in an Exchange Online migration at almost any level, it's likely you've run into the issue of cross-forest delegation. You know that Exchange allows you to delegate rights from one mailbox to another, allowing users to access other mailboxes. When you do an Exchange hybrid migration, there are some special considerations you have to take to keep these delegated rights working.
The third and final part of the Tenant to Tenant Migration series is about post-migration processing, and covers post-migration tasks that need to be done, measurement and reporting, what defines success or failure, and what things could be automated for the next tenant to tenant migration.
Almost every enterprise today is going through some type of transformation from historic compute solutions (i.e., “running IT in our data center”) to hybrid environments where workloads are distributed to specific locations, platforms, or providers based on business requirements. Even organizations seeking to be “cloud only” or “completely hyperconverged” will still have many environment types within their landscape. “IT everywhere” includes all the places we’d like to shift away from, like traditional corporate data centers, but won’t be able to due to technical debt and legacy systems.
In Part 1 of this blog series, we went through the topics of how to discover identities, workloads, data, and security for your tenant to tenant migration project. Part 2 of this series covers the migration itself, like which workloads can be moved, what needs to be done to prepare for the migration, what data can be migrated, if there are any gotchas to expect, and public available PowerShell scripts that make your life a little bit easier.
Microsoft 365 is not new. It’s been around for well over a decade, both in its current form as well as in its previous/current incarnation as Office 365, and before that we knew it as BPOS / Microsoft Online Services.
By now you must have heard that Microsoft is moving away from Basic Authentication and that all client authentications will move to Modern Authentication, and I've blogged about this previously.
Another thing that is happening is Microsoft moving away from TLS 1.0 and 1.1 and only allowing TLS 1.2 connections. This can have an impact on your organization too, so let’s have a look what is going to happen and why.
I expect we all know there are limits to what you can and cannot do with your Exchange Online mailbox. We all know there is a limit to how many emails you can send and receive, how much storage you can use, how much data you can move into or out of Exchange Online, and how big each individual email can be. However, I find that few Exchange Online administrators know exactly what those limits are, how they work, why they are there, or what you can do about them.
Welcome to part two of Addressing the Office 365 Monitoring Gaps. In part 1, Michael Van Horenbeeck discussed the differences in monitoring cloud-based systems vs traditional on-premises deployments.
