Professional email for your business — whether you need reliable hosted Exchange or the full Microsoft 365 productivity suite. CSP handles licensing, setup, migration, and ongoing support so your team stays connected and productive.
CSP offers two managed email paths. The right choice depends on whether you need just reliable email — or a complete business productivity platform.
Professional business email powered by Microsoft Exchange — without paying for apps your team doesn't need. Get your own @yourdomain.com addresses, shared calendars, contacts, and full Outlook integration at a simple, affordable monthly rate per mailbox.
The complete Microsoft cloud platform — business email plus Word, Excel, PowerPoint, Teams, SharePoint, OneDrive, and enterprise security tools. CSP licenses, deploys, and manages your Microsoft 365 subscription with local support your team can actually reach.
Three plans for businesses up to 300 users — CSP helps you select the right tier and manages your subscription from day one.
Web and mobile productivity with cloud email, Teams, SharePoint, and OneDrive. No installed desktop Office apps — all access is browser or mobile based.
Everything in Basic, plus fully installed desktop versions of Word, Excel, PowerPoint, Outlook, Publisher, and Access — on up to 5 PCs or Macs per user.
The full Microsoft 365 stack — Standard productivity apps plus enterprise-grade security, device management, identity protection, and compliance tools.
Microsoft 365 licensing is priced per user per month. Contact CSP for current pricing and to find the right plan for your team size and needs.

You can buy Microsoft 365 directly from Microsoft. What you can't get from Microsoft is a local Fresno team who knows your business, answers the phone, and takes care of the technical details for you.
Moving from an old email system or setting up email for the first time? CSP handles the entire migration — moving mailboxes, transferring calendar data, redirecting DNS — with no downtime and no lost emails. We do the heavy lifting so your team just picks up where they left off.
When something goes wrong with your email, you call CSP — not an overseas support queue. Our technicians know your environment, your users, and your business. Most issues are resolved remotely the same day. For anything complex, we can be on-site in Fresno.
New hire starting Monday? CSP provisions the mailbox, configures the device, and walks the user through getting set up. Employee leaving? We disable access, archive the mailbox, and ensure no data is lost — all handled promptly so you don't have to think about it.
Microsoft 365 ships with security features — but most require proper configuration to actually protect you. CSP enables multi-factor authentication, configures conditional access policies, sets up anti-phishing rules, and tunes your security defaults so you're protected from day one.
CSP consolidates your email licensing into a single monthly invoice alongside your other managed services. No surprise Microsoft billing changes, no confusing Azure cost reports — just a clear line item each month that covers your licenses and CSP's management fee.
CSP monitors your email environment — mailbox health, delivery issues, storage usage, and security alerts. We stay ahead of issues before they affect your team, and proactively recommend plan upgrades or adjustments as your business grows and your needs change.
CSP handles everything from plan selection to go-live — your team just shows up to working email.
CSP evaluates your current email setup, the number of users, your workflow requirements, and any compliance needs. We recommend the right option — Hosted Exchange or the appropriate Microsoft 365 plan — and provide a clear cost-per-user breakdown before anything is committed.
We handle domain verification, DNS configuration, mailbox migration, and security setup. If you're moving from an existing system — another Exchange host, Google Workspace, or on-premise server — CSP migrates all mailboxes and historical email with no data loss and minimal disruption.
Once live, CSP is your ongoing email administrator. We handle user adds and removes, troubleshoot delivery issues, manage security settings, and respond to support requests from your team — so you always have someone local to call when email matters most.
Beyond the license — CSP's managed email service includes the administration, support, and monitoring your team needs.
Whether you're setting up business email for the first time, migrating away from an old system, or upgrading from basic email to the full Microsoft 365 suite — CSP handles everything from start to finish and supports you every day after.

Your email platform is the foundation — but it needs a security layer on top. CSP's Email Spam Filter stops phishing and malware before they hit inboxes. Secure Email encrypts outbound messages containing sensitive data. Both pair with any email option above.
Not sure whether Hosted Exchange or Microsoft 365 is the better fit? CSP will walk you through both options and recommend what makes sense for your team, budget, and workflow.
