White Plains Microsoft 365 migration services

Professional firms in White Plains often have the most complicated email to move. Attorneys and accountants keep years of client correspondence, shared calendars for court dates and filing deadlines, and delegated access so assistants can manage a partner’s inbox. A careless migration breaks those arrangements and costs billable time. We inventory every mailbox, shared calendar, and delegate permission before anything moves, then rebuild them in Microsoft 365. Data copies in the background while the old system keeps running, and the final switch happens on a weekend, so Monday starts with the full history in place. Assistants can keep managing partners’ calendars without interruption.

Moving files deserves the same care. Client folders on an aging server can carry permissions that keep certain matters restricted to certain people, and those restrictions have to survive the move into SharePoint. We map them out and test access before go-live. As a Microsoft Partner, we also configure the security settings White Plains firms rely on, like multi-factor sign-in and retention policies, and we can keep managing your Microsoft 365 environment after the migration ends. Staff get a brief walkthrough of Outlook, Teams, and OneDrive after cutover, so the first week back is about client work rather than hunting for files.

Licensing & setup

The right Microsoft 365 plan for each person, reviewed as your team changes, so you aren’t paying premium prices for users who only need email and the Office apps.

Email & Teams

Mailboxes, shared inboxes, shared calendars, and Teams channels organized around your departments and projects, so conversations and meetings have a clear home.

SharePoint & OneDrive

File storage structured by department or client, with permissions that control who can see what, and personal OneDrive folders for work that’s still in progress.

Security configuration

Multi-factor authentication, conditional access, and threat protection turned on and tuned, since many of the most useful protections need configuring rather than leaving at their defaults.

Migrations

Email, calendars, contacts, and files moved from Google Workspace, older Exchange servers, or other providers, with the cutover planned so nothing is left behind and mail keeps flowing.

Account review & cleanup

For an existing Microsoft 365 account, a review of licenses, sharing settings, admin access, and old user accounts, followed by fixes for every gap we find.

User support

Help for your team with everyday questions, from a shared calendar that won’t sync to a Teams meeting that won’t start or a file that seems to have disappeared.

Can shared calendars and delegate access survive a Microsoft 365 migration?

Yes, when they are mapped ahead of time. BizTechPro documents which assistants manage which inboxes, which shared calendars exist, and who has access to each, then recreates those permissions in Microsoft 365. White Plains firms keep their docket calendars and delegation working on the first day after cutover.

Should a White Plains firm move from on-premises Exchange to Microsoft 365?

For most small firms, yes. An on-premises Exchange server needs hardware, patching, and security monitoring, and older versions have reached the end of Microsoft support. Microsoft 365 removes the server and adds built-in security options. BizTechPro, a Microsoft Partner, plans the move so mail, calendars, and contacts transfer without downtime during the workday.

How do you keep confidential client folders restricted after moving to SharePoint?

BizTechPro maps existing folder permissions on your server, rebuilds them in SharePoint with groups that match how your firm works, and tests access with real users before go-live. Restricted matters stay restricted. For White Plains law and accounting firms, that step is what makes a cloud move compatible with client-confidentiality obligations.
