Office 365 Backup Tool

Ans: Yes, the MacSonik Office 365 backup software offers an import feature that restores both PST and OST files into Office 365 mailboxes, archive folders, or public folders while preserving folder hierarchy.

Ans:The software allows to backup O365 mailboxes in a completely safe and secure manner. Even a single bit of information (like client name) is not shared by the application. Similarly, account credentials are not saved, neither on our server nor on any third-party system.

Ans: Yes, Office 365 backup and restore software is well suited to most of the popular Office 365 plans, including Business and Enterprise.

Yes, the MacSonik Office 365 Backup Tool uses Modern Authentication (OAuth) to securely connect with Microsoft 365 accounts, reducing credential exposure. During the backup process, mailbox data remains protected, and the software maintains complete data integrity, including emails, attachments, and metadata.

Ans: No, the MacSonik Office 365 backup tool performs backup operations without interrupting mailbox accessibility. Users can continue sending and receiving emails while the backup runs in the background. This makes it suitable for organizations that need continuous access during backup cycles.

Ans: The MacSonik software offers an Incremental Backup feature, which downloads only newly added or modified mailbox items instead of reprocessing the entire mailbox. This significantly reduces backup time, bandwidth usage, and storage consumption.

Ans: No, user access remains active throughout the backup process. The Office 365 backup tool works in a non-intrusive manner, so there is no need to lock, pause, or disable mailboxes during export.

Ans: MacSonik supports bulk mailbox export without size limitations, making it capable of handling enterprise-scale mailboxes. Combined with advanced filtering and incremental backup, it minimizes timeout risks and improves processing efficiency.

Ans: Yes, Admin Consent is required depending on the type of Office 365 data you want to access. For tenant-wide mailbox backups, shared mailboxes, or public folder operations, administrator approval is typically needed to authorize the application and grant the necessary Microsoft 365 permissions. This ensures secure and compliant access to organizational data.

Ans: Our Free Up Server Space feature deletes emails from Office 365 only after they have been successfully backed up or migrated to the selected destination. No emails are removed if the backup or migration is incomplete or unsuccessful. Additionally, deleted emails are moved to a recycle bin, allowing administrators to restore important messages if needed.

Ans: To migrate Office 365 Public Folders, the source account must have sufficient permissions to access and read the public folder content and metadata. Additionally, when migrating Public Folders to Public Folders, the destination account must have Owner permissions on the target public folders to allow the tool to create, modify, and transfer data successfully. Insufficient permissions on either the source or destination side may prevent the migration from completing.

Ans: No. Mail-enabling a public folder is not mandatory for backing up or migrating its contents in most scenarios. However, if you need to preserve email delivery functionality or migrate mail-enabled public folder attributes, the public folder should remain mail-enabled. The requirement depends on your migration objectives and environment configuration.

Ans: Yes. The MacSonik Office 365 Backup Tool can access and back up a user's mailbox even if the user's sign-in is blocked, provided that the backup is performed using an administrator account with the necessary Microsoft 365 permissions and admin consent. Since the mailbox remains active within the tenant, the tool can still retrieve and back up its data. However, the mailbox must not be deleted or inaccessible due to licensing or administrative restrictions.

Ans: Yes. The tool successfully migrates Contacts and Calendar data from Office 365 to Google Workspace while preserving associated metadata, including contact details, calendar events, reminders, recurrence patterns, and other supported properties, to ensure data integrity throughout the migration process.

Ans: Yes. A valid Microsoft 365 license must be assigned to each user mailbox that needs to be accessed or migrated. Without an active license, the mailbox may not be fully provisioned or accessible, which can prevent the migration process from completing successfully.

Ans: The tool automatically handles Microsoft Graph API throttling by applying retry mechanisms and respecting Microsoft 365 service limits. This ensures smooth and reliable backup or migration without data loss.

Ans: The application should be granted the following Microsoft Graph permissions: User.ReadWrite.All, Mail.ReadWrite, Contacts.ReadWrite, and Calendars.ReadWrite. These permissions allow the tool to access and migrate user mailboxes, emails, contacts, and calendar data securely.
