The Role of Email in Enterprise Unified Communications

Both Microsoft 365 and Hosted Exchange offer robust email solutions, but their ability to support broader communication strategies depends on how well they align with your organization’s specific needs.

Whether you prioritize real-time collaboration or require greater control over your email environment, understanding the role of email within your communication strategy is the first step toward making an informed choice.
