    Creating and receiving emails is simple. Managing contacts is a nice feature, especially connecting to Active Directory. Calendar management is also helpful and sharing access to others' calendars for scheduling meetings is useful. And reserving resources such as rooms or equipment is also useful. Personal and shared mailboxes are good features, as well. Tasks are a little lacking, but other than that, the features are thorough.

    RMail is great for sending emails with information that is sensitive but that the recipient is not going to put a lot of work into retrieving. I do psychological evaluations for criminal courts and I use it to send reports to courts and attorneys. I need to use something compatible with HIPAA privacy rules, which courts and attorneys are typically not as concerned about. If they had to use a password or go to an outside web address to retrieve the email, they wouldn't do it. It's also common for an attorney to say they didn't get an email, but I always know if they did or not, and I have clear documentation of it, which is important in legal cases.

    We have had a couple of legal inquiries which required us to review emails for a user or users. Using the Barracuda Cloud Archiving Service, we have been able to perform searches quickly, narrowing or expanding the search criteria is easy, resulting in exactly what we were looking for. This has saved us with claims for collections, as well as a couple of legal HR matters. It is my trusted go to application.

    Pros
    Microsoft
    • As we have a large user base of 11,000 users we use MailTips to avoid people getting confused with people with similar names in the organization.
    • The integration between Teams Meeting and Resource booking is generally very good. The Scheduling Assistance makes it easy to scan calendars and find free periods to provisionally scheduled events.
    • Marking yourself as Out of the Office and busy is easy, as is sharing your calendar within the team/organization or individuals.
    • Voicemail integration and the ability to receive missed chats in your inbox are highly used and useful.

    • Read receipts tell you the time a message was actually opened
    • The electronic signature feature is nice, and usually not included with these types of services
    • Many times, a recipient doesn't need a password to open their email. RMail leverages TLS technology in most cases
    • Recipients do have the option of creating an account, but generally they don't need to
    • Outlook integration is very easy to set up
    • Gmail integration within Chrome is pretty amazing

    Cons
    Microsoft
    • The two main factors for the better reliability & Uptime of internally hosted Exchange Server depends on Exchange Server configuration and the level of investment the organization is willing to provide for hosting the Exchange Server On-Premise Environment. As the data is stored in the organization’s hardware, any disaster may lead to the loss of email and servers.
    • Losing data might affect business continuity and rebuilding it can be costly.
    • Security remains a major concern.
    • Security of data loss is main concern. To ensure that, organization needs to configure networks, systems and Exchange platform against possible threats.
    • Hardware and license costs are high.

    • Issues can arise if your computer's clock is not synced to RMail's time servers.

    Email and calendars in a business setting are requirements. And Microsoft continues to be the standard of business applications. Microsoft 365 makes Microsoft Exchange easy to use. Everything is in the cloud. Let Microsoft take care of the hardware, the software, and the security. You just enable your business users with the functionality they need.

    I don't think RPost has any competition, at least none that I can use. I think that once registered email becomes widely accepted (someday soon?), it will be indispensable for anyone in business, and RPost is the leading vendor (maybe the only vendor).

    Microsoft Exchange has come a long way over the years and has nowhere near the technical overhead required for support as it did back in 2003/2007 and prior. The integrations with Teams, Defender, Sharepoint, Copilot and many other products make it a solid and well-rounded tool used for many day-to-day tasks.

    We have a good enterprise agreement with Microsoft which affords us quick phone support. I have found the support staff knowledgeable and prompt with a solution when required. At times it may be difficult to schedule a call back, this is mainly due to our need for calls early in the morning which happens to be during a shift change at Microsoft support.

    Support is easy to access via email or phone. They also reach out to you periodically with new features, but they aren't intrusive about it. I usually appreciate it when I get an email from RMail, which is not very often.

    Microsoft Exchange Product The best cloud-based enterprise-grade archiving platform with a host of features that enable files to be securely archived and retrieved with advanced search options. This tool is very easy to use and has a User-friendly interface. It is a highly reliable platform that allows all employees to automatically store their data without any limitations. It offers a cost-effective solution with customized policy management. We are happy that the customer support team is always fast and concerned, and the product's uninterrupted service experience.
