The latest version of AhsayOBM is installed on the remote backup machine which is connected to Office 365 and AhsayCBS backup server through internet.


Follow the steps in the above mentioned guide to perform the following configurations first.

Granting Permission to Accounts for Creating Backup Set

Before the Office 365 account administrator or other accounts can create a backup set, the administrator has to grant permission to the account(s) which are going to create backup set. The account must be a member of the following security groups:

  • Discovery Management
  • Public Folder Management

Granting Permission for Application Impersonation & Mail Search

This permission allows users added under the Members section of the Discovery Management group (refer to the previous section for setup) to back up and/or restore user item(s) not only for their own account, but also the accounts of other users in the same Members section. To grant permission for this feature, you have to add the Application Impersonation & Mail Search role by following the steps below.

Granting Permission for SharePoint Global Admin

The Global Admin permission allow SharePoint account to list other account’s  Personal Site and OneDrive in the backup source tree. So before using AhsayOBM to create backup set, please ensure the SharePoint account has already owned the permission in order to apply AhsayOBM to back up and/or restore user item(s) not only for their own account, but also the accounts of other users.

From hardware failure to natural calamities, there are quite a few unexpected events that can lead to precious data loss. When working with Microsoft Office 365’s cloud platform, many organizations might think that the data is stored in the cloud and cannot be lost. Although Office 365 provides archiving tools, such as Litigation Hold, it only provides long-term data retention that is no longer actively used. The process is tedious and complex even if a user wants to recover a single email. For this, MSPs require a third-party backup solution to offer to their clients. This is where Ahsay backup comes in. With robust security mechanisms, the company provide cloud-to-cloud / cloud-to-local data backup for all kinds of Office 365 Exchange Online mailbox files.

This is the reason we hire only the best people and employ the most modern technology. Constant improvement has been the reason for our continued success over the years.”

With its solutions, Ahsay has become a preferred choice for MSPs across the world. The company has helped solve data backup needs for a wide variety of clients.

5 Common Office 365 Backup Mistakes You Need to Avoid

From accidental deletion to hacker attacks, your data is not safe, even with the Microsoft Office 365 platform.

It has been (wrongly) assumed that once your data is in the cloud, it is completely safe. Although moving to the Office platform allows you access to its incredible programs, such as PowerPoint, Excel, and Outlook, it also means that you need to be more careful with data backup.

When offering Office 365 data backup, MSPs need to inform their clients about relevant pitfalls. Here are some data backup mistakes that need to be avoided:

1. Trusting the Recycle Bin for Recovery

When users delete files or emails, they get into Recycle Bin. Although the files can later be retrieved, it is quite difficult to find that particular file in Office 365’s Recycle Bin. This is because there are no search options for Recycle Bin, so users have to manually search through each file. This might take a lot of time and effort.

What’s more, there is a limited retention period in Office 365. Once that retention period is over, you might lose the file forever.

2. Relying on Office 365’s Archiving Tools

Some latest versions of Office 365 offer archiving tools, like In-Place Archiving and Litigation Hold. Although these tools can come in very handy when retrieving data for audit, they are not aimed at providing recovery of personal data.

Also, activating In-Place Archiving and Litigation Hold will require delving into complex configurations of Microsoft.

3. Not Protecting All Data Types

From important dates in the calendar to contact information, all the different data types need to be protected.

Make sure you have got your basis covered as you might need to retrieve even the smallest piece of data.

4. Not Protecting Office 365 Applications

This is one of the biggest mistakes that IT operators might make. From SharePoint Online to OneDrive, more and more file sharing platforms have come to the fore. The data from these file sharing platforms also needs to be backed up. If it isn’t, you might lose it forever.

5. Choosing an Unreliable Office 365 Backup Provider

When looking to backup Office 365, you need to opt for a platform that provides highly reliable backup solutions.

Any lapses in security or less than efficient storage mechanisms must raise red flags. Make sure you find a reliable Office 365 backup provider to keep your precious data intact.

What Ahsay Offers

With a team of extraordinary professionals and robust security mechanisms, Ahsay provides efficient Office 365 backup. By backing up Office 365 Exchange Online mailboxes, contacts and calendars, the company ensures that your client’s data remains safe. 

Microsoft Office 365 Backup – Why MSPs Should Provide It


Since its introduction in 2011, Microsoft Office 365 has achieved incredible popularity. The suite allows businesses to use Office applications online. Apart from the usual Word, Excel and PowerPoint applications, it also includes cloud storage in the form of OneDrive and hosted versions of applications, such as Skype, SharePoint and Exchange.

Although its SLA (Service Level Agreement) guarantees great uptime, data loss is still one of the major concerns for businesses. This is where you, an MSP, enter the picture. For customers who have implemented Office 365 in their operations, it is important that you provide data backup and recovery solutions, specific for Excel, Word, PowerPoint, email, etc.

Here are some reasons why MSPs should provide an Office 365 backup:

1. Deleted Items in Office 365 Are Permanently Discarded After 14 Days

Sometimes, data might get accidentally deleted. Before someone realizes that a particular file is missing, it can be too late.

Although Office 365 offers data archiving tools, it does not provide complete protection against deletion.

You, as an MSP, can prove to be quite helpful here. With a robust Office 365 backup plan, you can provide data protection against deletion and save businesses valuable time.

2. Restoring a Lost Email Can Take Hours

From project planning to file sharing, email is the most important tool of communication for businesses. With many employees constantly connected through Office 365’s Exchange Online, it would be a disaster if an important email is lost.

Possible causes of this can be accidental deletion or malicious activity from an outside source. Exchange Online also keeps emails safe for 14 days; after which, retrieving them becomes impossible.

An MSP can provide email protection to businesses. This helps business owners have peace of mind.

3. SharePoint Online and OneDrive Do Not Have Any Archiving Features

Both SharePoint and OneDrive are tools that allow IT professionals and other staff members to share and organize files. They also help staff members work remotely.

When it comes to SharePoint and One Drive, users might (falsely) assume that since their files are on the cloud, they cannot be lost or corrupted.

MSPs can provide efficient backup and auto-discovery solutions to ensure smooth functioning of companies. Their robust mechanisms can help make it easier to find the deleted files and quickly restore them to their location. This can significantly enhance a company’s operations.

Ahsay is one of the leading managed backup service providers to MSPs. Their robust cloud-to-cloud backup ensures comprehensive data protection. Know more about them.

Why Offer Office 365 Exchange Online Backup Solution to Your Customers?


Microsoft Office 365 is the most common business productivity suite nowadays, and millions of organizations have migrated their on-premises Exchange email infrastructure to Office 365 Exchange Online. There circulates an opinion that once the email data is in the cloud there is no need to worry about backing it up. After all, Microsoft guarantees 99.9% uptime and the fidelity of customers’ Office 365 data within their data centers. But does it mean that Microsoft provides adequate data backup and restorability that meet the business needs or internal service level agreements? As MSPs, take a closer look and it is not difficult to find good reasons to offer Office 365 Exchange Online backup solution to your customers.

Microsoft only protects customers’ data from disasters that happen at its data centers

Database Availability Group (DAG) is Microsoft’s core technology for protecting Office 365 Exchange Online data. With multiple data centers located all over the world, the redundant network architecture hosted by Microsoft ensures that if an outage occurs at one data center, another can function as backup. While customers’ Exchange Online data is protected from catastrophic disasters that may happen at Microsoft’s data centers, it is not safe from unpredictable incidents such as:

Deleted item recovery is restricted to retention policy

When user deletes a message, it goes to the Deleted Items folder. If the message is removed from the Deleted Items folder, it moves to the Recoverable Items folder where it is stored for 14 days by default, and the retention period is a policy that can only be extended at administrator level. This is the first line of defense as users can still retrieve a deleted item as long as its retention period has not elapsed. But after that period, the message disappears permanently because emails purged from the Recoverable Items folder cannot be recovered. Users would need to contact Microsoft support and wait for a solution with no timeline guaranteed.

Item-level recovery is far from adequate

Item-level recovery alone is far from adequate. If a folder has been deleted from Deleted Items, one can recover only single items that the folder included, not the folder itself. It means that emails will be recovered to Inbox, not to the original folder. As pointed out by a Microsoft MVP, item-level recovery only protects an organization against deleting items such as email messages, but it does not allow recovery of a corrupt mailbox. Microsoft has designed Office 365 in a way that organizations do not need to worry about the core infrastructure, but has also limited the administration and end user backup and restore capabilities. Microsoft admitted that point-in-time restore functionality is also absent in Office 365 Exchange Online. In case the state of mailbox data is damaged due to unexpected third party activities such as hacker intrusion or on-purpose deletion, administrators would not be able to recover the mailbox data to an earlier point in time.

In-Place Hold or Litigation Hold is not without limitation

Microsoft does offer a functionality to put a mailbox on In-Place Hold or Litigation Hold for keeping all data in the Recoverable Items folder indefinitely. This option is solely for legal actions in a company and is available only in the most expensive Office 365 Enterprise Plans E3 and E4. It is important to note that the size of the Recoverable Items folder of the mailbox may increase quickly depending on number and size of items deleted or modified. Once the 100GB quota is exceeded, Office 365 will start to delete data from this folder and the data may become non-recoverable.

Recovery using an exported PST file is time-consuming and cumbersome

As a last resort, administrators can search for deleted emails using eDiscovery and export the deleted data to a PST format file. The major downside is that only one mailbox can be exported at a time and there are no PowerShell cmdlets for that purpose, which means it would take a great deal of time for administrators to handle a large number of user mailboxes. Besides, deleted emails found by eDiscovery are not recovered directly to an original location; administrators need to export them to a PST file first, then import to the user’s mailbox, and move the emails manually to original folders. Moreover, a desktop version of Outlook is required to restore deleted emails using a PST file because the Outlook Web version cannot open PST files. This whole process of recovery consumes a lot of time and resources from IT admins and could consequently impact the business.

It is a golden opportunity to offer Office 365 Exchange Online cloud and local backup solution

The native Office 365 Exchange Online backup and restore methods are in no way a comprehensive backup and restore solution and are insufficient to avoid critical data loss. No companies can risk all of their critical mailbox data being in the hands of one provider. As more and more customers are looking for a way to back up their Office 365 email data to another location, it is a golden opportunity for MSPs to tap into the ever-growing Exchange Online data backup market.

Ahsay’ Office 365 Exchange Online Backup

We have a complete Office 365 Exchange mailbox backup solution that empowers you to give your customers absolute peace of mind. It is a fully automatic backup system that backs up Office 365 Exchange data to a local server or another cloud, and enables quick recovery of full mailboxes or individual items with just a few clicks.
