Briefly about migrating Microsoft Exchange server to Exchange Online
Migrating an on-premises Exchange server to Exchange Online (Microsoft 365) This is not only a step towards modern work, but also real savings and greater data security. For many companies, this means an end to server outages, manual administration, and costly updates.
Our company provides comprehensive support for such migrations – from the initial audit, through environment preparation, to the transfer of all mailboxes, contacts, and permissions without disrupting the team's daily work. We work with both small and medium-sized organizations that require technical support and a clearly defined timeline.
Most common problems
Often, after moving mailboxes to the cloud, Outlook cannot be connect correctlyThis is due to outdated Autodiscover entries or DNS errors. We can help resolve these conflicts.
Customers are unsure whether to choose a cutover, staged, or hybrid migration. We recommend the best method based on the number of users and the Exchange server version.
A poorly executed migration can result in data loss or incomplete mailboxes. Therefore, we perform test migrations and create backups before the migration.
Manually migrating dozens of mailboxes is time-consuming. We automate this process using PowerShell and the Exchange Admin Center.
Old certificates can block hybrid migration. We can help you renew them or implement secure workarounds.
Moving data to the cloud can be time-consuming over slow connections. We recommend nightly strategies and plan migrations in batches.
After migration, you may lose access to calendars, shared mailboxes, and folders. We can help you fix this and automate the restoration of permissions.
Exchange Online is not a substitute for a full backup. We implement Microsoft 365 mailbox backup solutions in accordance with company policy.
Active Directory integration may cause synchronization errors. We're verifying the configuration. Azure AD Connect and we secure the process.
Adding a new section, updating contact details or an offer – without technical support, even simple changes can be problematic.
