Microsoft Exchange OnPremise & Online services
In On-Premise your business holds the responsibility of performing software and hardware upgrades manually in accordance with your schedule. On-Premises may not receive a newer version beyond 2016. The accessibility of Exchange On-Premises, is subject to existing infrastructure setup, and strategies for disaster recovery — which means that it is completely dependent upon company IT staff. With Exchange On-Premises, you can define mailbox quotas in accordance with your organizational requirements. And mailbox quotas are limited only by the capacity of the server’s hard disk storage. While the migration process to Exchange Online from Exchange On-Premises is challenging, it is still the most viable option to avoid the escalation of compatibility issues in the future.
