Pricing Comparison
When we delve into the pricing aspect of Zimbra and Outlook, it’s crucial to understand that both offer different models catering to various business needs. Zimbra provides an Open Source Edition, which is free, but for businesses requiring additional features and support, the Network Edition comes into play with its own cost structure.
| Zimbra Network Edition | Price per Mailbox/Year |
|---|---|
| Professional | $30 – $45 |
| Standard | $25 – $35 |
| Starter | Approx. $10 |
The exact pricing can vary based on factors like vendor discounts, volume licensing, and additional services packaged by resellers.
On the flip side, Microsoft Outlook is part of the Office 365 suite. The subscription model includes several tiers:
- Microsoft 365 Business Basic: starts at about $5 per user/month
- Microsoft 365 Business Standard: begins around $12.50 per user/month
- Office 365 E3: typically priced at roughly $20 per user/month
These prices are indicative and subject to change depending on promotions or changes in Microsoft’s pricing policy.
It’s worth noting that while individual licenses for Outlook do exist as one-time purchases under the name “Outlook standalone,” they lack the collaborative features intrinsic to Office 365 subscriptions.
For enterprises considering total cost over time, remember that a subscription-based model like Office 365 may initially seem more expensive than a one-off purchase or open-source option. However, this recurring expense includes updates and technical support, which could otherwise incur additional costs down the line.
