A good solution for large enterprises, but is expensive when compared to other solutions
Regarding the decision of increasing the number of users, it depends on the organization's choice, whether to opt for CapEx or OpEx. Both options involve expenses over the years. Building an in-house Exchange solution requires investing in hardware, storage, connectivity, and administrative resources. Office 365 shifts the budget solely to OpEx as a subscription service. Scalability is another factor. Starting a new company favors Office 365 due to cost efficiency. As the organization grows, the choice depends on available resources and technical expertise. An internal Exchange setup is feasible with skilled engineers, while Office 365 suits those lacking in-house resources.

Offers good user interface and seamlessly integrates with other Microsoft services
I like its user interface. I don't struggle or face any challenges while using it. The design interface is simple. I haven't had any trouble managing it for a long time. Even if I encounter a challenge or two, I can always reach out to Microsoft for help. So, overall, it's been a very positive experience. Having everything under one account was valuable. I just had to go through cybersecurity for licensing and download everything. With one account, you can download Office and use Online features directly from your Exchange. There are security solutions in place, and we take customer data very seriously. For example, if I accidentally create a forwarding rule or send an email with an image attached, I get a notification immediately. Compliance-wise, it's quite good online. We can do many things. Even if I can't click on something or upload a specific file type, it'll still be stored for compliance or investigation purposes. So, subscribing to these features. The benefits are widespread and effective communication. We use Microsoft Teams for meetings within and outside our organization. Additionally, Teams can be used for chat, allowing us to track communication and see user activity. Those are the key points that have proven to be beneficial.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Technical support is good."
"The technical support services are good."
"Scalability-wise, I rate the solution a ten out of ten."
"The solution can scale well."
"The product can scale."
"It gives me benefit in terms of integration with other services such as SharePoint, Microsoft Teams, and OneDrive. It makes my work much easier."
"Customers can benefit from this new pricing model because it's expensive and now with the subscription they can budget for this."
"The deployment is a plug-and-play process."
"It is very manageable."
"When you used to write to someone, you would often begin typing their name and their email address would appear; you would simply click and you would have the correct email address. That has been working for a while, but having the location address appear was a pleasant surprise. It was amazing."
"There are many valuable features such as email, calendar, and the ability to share your calendar and documents with coworkers. Knowing that the emails go through the EOP filtering service is nice as well."
"The best part of this solution is the security it offers."
"Microsoft Exchange Online is a stable product."
"It's not hard to set up."
"The data prevention and protection feature is good."
"The product’s most valuable feature is the online archive."
 

Cons

"It is costly, so it depends on how much you want to pay."
"The licensing model could be improved."
"The solution is stable, but it could improve. It's crashing if there is a big mail database. The Zimbra solution is better in this area."
"Load balancing is lacking."
"The desktop version of Microsoft Exchange receives emails a little slower than the online version."
"There can be occasional challenges during the product's implementation phase, making it an area where improvements are needed."
"I would like to see Microsoft Exchange improve their documentation."
"If it was the same product, and slightly cheaper, that would be amazing."
"When you migrate from on-prem to cloud, if you choose to or are forced to do the hybrid, they need to devise a way to undo the hybrid."
"What I don't like about Microsoft Exchange Online is too much integration because now it has many services connected to it. In the beginning, it was just email, and now it's also Teams and Visio, and many other services which I don't like. Microsoft Exchange Online should focus on one service. The product now lost focus, and this is its area for improvement. I would also like more freedom in choosing to use just one service, for example, just Microsoft Exchange Online, which means I don't need Teams or any other Microsoft product or service there. Right now, all services are either in the Microsoft Office suite, or there are more products or services integrated with Microsoft Exchange Online, and I'd like to just focus on one."
"They should tighten their cloud security."
"There is room for improvement in terms of security, as it could be better."
"Using this solution is initially quite complicated."
"The solution should have more integration with other platforms."
"The support from the vendor is fine. However, it could be faster, and some of the agents could be more knowledgeable, but it is a large solution, there's a lot of information that the agents have to work with. I can't always expect when I get connected to the first-level agent that they will know absolutely everything. Sometimes there's no replacement for pure experience."
"Documentation is lacking."
 

Pricing and Cost Advice

"Its price is okay."
"It would be nice if it used less resources to run on-premise."
"Its price is very affordable, and basically, it is the standard of the industry. We have the Exchange 365 subscription, which includes the usage of Exchange Online. I don't know the specific cost, but it is the retail price of Microsoft 365 E3 licenses. Microsoft's licensing is not very easy to understand. Microsoft changes rules every other day, which makes it difficult for us to understand the licensing not only for Exchange but also for other products. It can sometimes be really complex to understand what you need to have in order to comply with Microsoft licensing."
"Microsoft Exchange itself does not require a license, but users who will have mailboxes will require a license. It depends on the number of users to choose which license. If you exceed 2,000 mailboxes, it's preferable to get the enterprise license."
"I rate Microsoft Exchange a four out of ten for pricing because it is quite cheap, and many companies use the solution."
"Microsoft Exchange is an inexpensive application."
"Since my company is on Microsoft Cloud, we pay for the licenses per user. Compared to volume licensing, I would say the present licensing cost is not expensive."
"There is an annual cost to use Microsoft Exchange, and the price could be less expensive."
"We pay a yearly licensing fee for the solution."
"This solution requires a license."
"We have yearly licensing costs."
"The product is expensive and has an annual subscription."
"My company needs to make monthly payments towards the licensing costs attached to the product. I feel that the price of the product is affordable."
"The pricing for Microsoft Exchange Online is quite reasonable, in my opinion. Many licensing options are available so that we can choose based on the customer's needs. For example, if a customer only requires mailbox features, we can recommend Plan One or Plan 2. We can suggest an E3 or E5 license if they need the entire Office suite. There are also premium subscriptions for enterprise customers, offering additional security features. Overall, I don't find the pricing costly because Microsoft provides many features and security capabilities, making it reliable for all customers, depending on their requirements."
"The pricing is based on a yearly contract and a floating license option is offered."
"The pricing is a bit more expensive than other solutions."
