Migrating large Exchange archive mailboxes to the cloud poses a significant challenge due to throttling issues that can hinder the smooth transfer of data. Throttling, a mechanism designed to maintain system performance and prevent overload, often occurs during migrations of large volumes of data, such as Exchange archive mailboxes. Microsoft’s article on auto-expanding archiving highlights the importance of being aware of throttling limitations when transferring large amounts of data to the cloud. Throttling can significantly impact migration efficiency, leading to extended time-frames, failed migrations, and frustration among end users.
In this blog post, we will address the throttling problem organizations face during such migrations and present a solution that simplifies the migration process by mitigating throttling concerns. Our approach combines industry best practices with innovative strategies to ensure a seamless transition of large archive mailboxes to the cloud.
To overcome throttling challenges, we recommend leveraging specialized migration tools designed to handle large data volumes efficiently. One such solution is Priasoft Super ExMerge. This powerful tool incorporates features specifically tailored to address the throttling issues encountered during the migration of large Exchange archive mailboxes. Let’s explore how Super ExMerge can help simplify your migration process and mitigate throttling concerns:
- Dynamic Multi-Threading: Super ExMerge intelligently manages threads during the migration, ensuring the maximum utilization without overwhelming the system. This feature optimizes performance, minimizing the impact of throttling and expediting the migration process.
- Multi-Process Capability: Leveraging the power of multi-process architecture, Super ExMerge can handle multiple migration tasks concurrently. By utilizing available CPU and RAM resources efficiently, it significantly improves throughput and mitigates throttling-related slowdowns.
- Efficient Data Transfer: Super ExMerge only copies new and changed data, thanks to its full fidelity synchronization tracking. This smart approach eliminates unnecessary data transfer, reducing the overall volume of data to be migrated. As a result, throttling concerns are alleviated, and the migration process becomes more streamlined.
- Granular Control and Folder Exclusion: Administrators have granular control over the migration process, enabling them to select specific folders or subtrees for synchronization. Additionally, the ability to exclude certain folders minimizes the migration load, addressing potential throttling issues effectively.
- Authentication Flexibility: Super ExMerge allows each migration task to authenticate with different accounts, distributing the migration load across multiple credentials. This capability prevents throttling limits imposed by Microsoft Exchange, ensuring a smooth and uninterrupted migration.
- Comprehensive Reporting and Logging: Super ExMerge provides detailed reports and logs, offering valuable insights into the migration progress. Administrators can closely monitor the process, identify potential bottlenecks, and take necessary actions to mitigate throttling challenges promptly.
By adopting our alternative solution and utilizing specialized migration tools like Priasoft Super ExMerge, organizations can streamline the migration process and mitigate throttling concerns. This approach ensures a seamless transition to the cloud, minimizing downtime, maximizing data integrity, and enabling your organization to fully embrace the advantages of a cloud-based infrastructure.

Microsoft Office 365 is now available for US National Security Missions.
The Office 365 Secret Cloud provides a secure and compliant cloud environment for classified communications and collaboration. This capability is critical for national security agencies that need to protect sensitive information from cyber threats and foreign adversaries.
The Office 365 Secret Cloud is built on Microsoft’s Government Community Cloud (GCC) High infrastructure, which has been authorized by the Department of Defense (DoD) for Impact Level 5 (IL5) workloads. The IL5 designation means that the cloud environment is suitable for the most sensitive unclassified and classified information, including national security data.
One of the key benefits of the Office 365 Secret Cloud is that it enables collaboration and communication between different national security agencies. With traditional communication methods, it can be difficult to share information between agencies due to security concerns and restrictions. The Office 365 Secret Cloud allows authorized personnel from different agencies to securely collaborate and communicate in real-time, making it easier to share information and coordinate efforts.
The Office 365 Secret Cloud also provides a range of security features to protect classified information. These include multi-factor authentication, encryption at rest and in transit, and threat detection and response capabilities. In addition, Microsoft employs a dedicated team of security experts who monitor the environment 24/7 and respond to any security incidents that may occur.
The availability of the Office 365 Secret Cloud for US National Security Missions is a significant milestone for Microsoft and for the national security community. It demonstrates Microsoft’s commitment to providing secure and compliant cloud solutions for the most sensitive workloads, and it enables national security agencies to work more efficiently and effectively by providing a secure environment for collaboration and communication.
In conclusion, the Office 365 Secret Cloud is a game-changer for US National Security Missions.

Something we have seen that may have been missed by many customers and admins is a quietly published article about Microsoft support for the Office Suite in 2020 (a little more than a year from now!).
This article was found by reviewing the Office 365 Message Center articles back in 2017. Unfortunately, the default view provided by this feature only shows the last few months of articles and the one from 2017 no longer appears.
The article that was posted seems harmless at the time and had a simple statement about Office 365 support in 2020. Most people in our experience never saw this article.
The article indicated that in 2020, Office products that would be used to connect to Office 365 would only be supported and usable by the then current version of Office that was installed from your Office 365 tenant. Our reading interprets this to mean that possibly the retail versions of the Office product will not be usable against Office 365, even if it were the most recent version (Office 2019 as of today).
We suggest all customers of Office 365 to continually review the “Message Center” messages that are posted as well as the “Service Health” advisories. Many changes to Office 365 are announced thru the Message Center, but many changes that can have considerable impact on the enterprise are not announced with any loud or attention-grabbing fanfare. In addition, given that Microsoft may announce changes that are many years in advance of the actual change, such announcements will fall out of view in a few months.
Here are some of the specific details regarding the changes that are scheduled for the latter half of 2020:
