Itools Exchange Online Plan 2, MNT (on request) on Windows Emails

Exchange Online Plan 2 is the top tier Exchange based mailbox service in this product group and is designed for users and departments that require exceptional storage capacity and advanced protection. Each user receives a 1 TB primary mailbox together with a 1.5 TB archive mailbox, providing an enormous 2.5 TB of total storage. This is ideal for roles that must retain email for many years, such as legal, finance, or executive teams, and for organizations with strict compliance or audit requirements. Messages up to 150 MB in size are supported, so even very large attachments can be sent and received without routinely hitting size limits.
Like Plan 1, this tier incorporates strong malware and spam filtering alongside data loss prevention tools that help prevent sensitive information from being sent to the wrong recipients or outside the organization. Users have rich address book and calendar features for scheduling meetings, managing contacts, and coordinating tasks. A firewall perimeter and two factor authentication improve account security while iTools engineers monitor and maintain the service. Exchange Online Plan 2 is therefore suited to businesses that want a fully managed, very high capacity email and archive platform with enterprise grade security and collaboration tools, delivered as a cloud service from the iTools infrastructure.

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.
