- 2. Deploy to your team: Install WPS Office across your users' devices to immediately provide word processing, spreadsheet, and presentation tools.
- 3. Work seamlessly: Open, edit, and save Microsoft Office files received via email without formatting loss.

Frequently Asked Questions
What is the maximum number of users for Microsoft 365 Business plans?
Microsoft 365 Business plans (Basic, Standard, and Premium) support a maximum of 300 users. For an organization with 200 users, these plans are fully applicable. If you ever exceed 300 users, you must upgrade to Enterprise (E3/E5) plans.
How much mailbox storage is included in standard Microsoft 365 Business plans?
Microsoft 365 Business Basic and Business Standard plans include a 50 GB Exchange Online mailbox per user. If greater capacity is needed, upgrading to Exchange Online Plan 2 or an Enterprise plan increases the limit to 100 GB.
Is archiving included in the 50 GB mailbox limit?
No, the 50 GB limit applies only to your primary inbox. Most Microsoft 365 Business plans include an additional 50 GB archive mailbox by default. For unlimited archiving capabilities, specific add-ons or higher-tier plans are required.
Can I mix and match Microsoft 365 plans for different users?
Yes, you can mix different plans within the same tenant. For example, you can purchase Business Basic for 150 users who only need email and web apps, and Business Standard for 50 users who require the full desktop office suite.
