Itools Exchange Online Plan 1, MNT (on request) on Windows Emails

Exchange Online Plan 1 is a hosted Exchange style email solution that targets businesses needing very large mailboxes and native support for collaboration features. Each user is provided with a 500 GB primary mailbox plus an additional 500 GB archive mailbox, for a total of 1 TB of storage per user. This structure allows staff to keep their active mail in the main mailbox while moving older messages into the archive, supporting long term retention policies without losing access to historical data. The plan supports messages up to 150 MB in size, so large documents and media files can be exchanged without having to rely on external file transfer tools for many use cases.
Security features are strengthened beyond the standard business email packages, including malware and spam protection tuned for Exchange workloads and data loss prevention capabilities that help control how sensitive information is shared. Built in address book and calendar functions support scheduling, meeting invitations, and contact management directly within the Exchange environment. A dedicated firewall and two factor authentication options help protect user accounts and access to the service. This plan is appropriate for organizations that want enterprise level mailboxes with robust archiving and compliance friendly features while keeping the platform fully managed by iTools in their Mongolian data center.

All business email and Exchange plans are delivered from the iTools data center in Ulaanbaatar, ensuring that corporate mailboxes are hosted on national infrastructure with reliable power, connectivity, and environmental controls. The service is designed to replace generic consumer mailboxes with professional addresses based on your own domain name so that every message reflects your company identity and brand. Incoming and outgoing messages pass through layered protection including antivirus and antispam filtering, forged mail detection, and firewall policies so that employees are better protected against malware, phishing, and unwanted bulk mail.
Mailboxes can be accessed from webmail, desktop clients such as Outlook, and mobile devices, making it easy for staff to work from the office or on the move while keeping folders, calendars, and contacts in sync. The platform supports features like address books, shared calendars, and large attachments up to 25 MB, and storage tiers scale from small mailboxes to very large Pro and Exchange options with dedicated archive space. Customers order and manage their services through the secure self service portal, where they can view invoices, add or remove mailboxes, and request changes. Around the clock technical support from certified engineers is available by phone, email, and online helpdesk so that any issues can be resolved quickly, and the extensive help and FAQ resources explain topics such as ordering requirements, using the service without a separate hosting plan, configuring mobile devices, and dealing with spam.
