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

"Functionality wise, I can't really say it's improved from Exchange Online, I think it's not so much change on-premise."
"I couldn't delete an email account because it was identified as my primary account by the application."
"The solution could improve with the integrations with some of the known applications is still not possible, there must be more connectors."
"The pricing could be cheaper."
"Microsoft Exchange Online can improve message delivery. There are times we receive a message that the email failed to be delivered, and there is no reason given. We sometimes have emails that are flagged as spam that are not. We cannot do anything about it because it's not managed by us, it's managed by Microsoft."
"The interface is a bit confusing."
"Encourages endless inefficient communications. Do not recommend it for companies that are trying to create efficient decision making processes and agile movement."
"The price could be an area of concern for many."

"The pricing for this solution is good. We renew our contract every three years. I would rate the pricing for this solution a three out of five."
