Offers flexibility and cost-effectiveness with multiple service options but could improve support and mobile features
There are many things to consider about email management in Microsoft Exchange Online. The online management is good, the storage is sufficient, and we use most of the features such as the custom rules in Microsoft Exchange Online, which we cannot find in any other email solution. That is a very good option, as we have many options to create custom rules in Microsoft Exchange Online. Regarding security features in Microsoft Exchange Online, we also use Defender for Exchange which includes the basic Exchange Online protection that has spam and threat controls. The use of Defender is beneficial for our security. The flexibility of choosing plans in Microsoft Exchange Online is good. We have chosen the best plan for our use, including multiple licenses such as plan one and business basics, which leads us towards cost-effectiveness, and the pay-as-you-go option is more flexible. Microsoft Exchange Online is very scalable.

Quick solution, but not very user-friendly or suitable for collaboration
It's not a good solution for collaboration. We're using it because of the price. It's not very strong or comparable with Office 365. An additional feature I would like to see is the ability to connect from different devices. Zimbra could be more user-friendly and deploy security rules. The integration with Outlook could be better to share agendas.

Cons

"The solution should have more integration with other platforms."
"The interface is a bit confusing."
"I think that the price is a little high, especially considering that Google have a similar, free email solution."
"Tech support is a challenge at times. They take a long time to respond."
"The solution should have a stand-alone application instead of us having to go through an internet browser."
"Exchange Online has issues with its mail flow and content search."
"Also, I think the mobile app on the forms you can improve a little bit more."

Pricing and Cost Advice

"I would give the cost a five out of ten."
"The subscription fee is monthly."
"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 could be improved."
"I have no opinion."
"The licensing price is ok, I'd rate it as four out of five."
"The licensing cost increased at least 15 to 20 percent recently and it would be helpful for them to be reduced."
"The cost of Microsoft Exchange Online is approximately $4 to $36 per user. They do not give a discount which is not good. The solution is expensive if you have 800 to 1,000 users. They should give discounts when you have a lot of users."
"It's an open-source solution so it's free."
