MailPlus, Note & Calendar - Synology's Office Suite

What "Self-Hosting" Means

Self-hosting simply means the service runs on your own equipment instead of someone else's. Your calendar, notes, and files live on the Synology box in your home or office - not on a distant company's servers.

When you use most online services, your information sits on computers owned by a big company. With self-hosting, that same information sits on hardware you own and control. You are the landlord, not a tenant.

• Control. Your data stays on your NAS. You decide who can reach it.
• Privacy. No outside company is mining your notes or email for advertising.
• No monthly rent for the service itself - you already own the NAS.

An Overview of the Productivity Suite

Synology offers a whole set of office apps, each a separate package you install from Package Center in DSM. You pick only the ones you want. Here is the family at a glance.

Most of these lean on Synology Drive underneath, which is the file-sync engine that stores and shares the data. You do not have to understand all of that - just know the apps work together and store everything on your NAS.

MailPlus - Running Your Own Email

MailPlus lets your Synology act as a full email server, so your messages flow through hardware you own. It is genuinely capable. It is also, by far, the most demanding thing in this guide - and I want you to know that up front.

Running email is not like running a calendar. An email server has to talk to the whole internet, prove it is trustworthy, fight off spam, and never quietly drop a message. Get any of that wrong and mail silently disappears or lands in strangers' junk folders.

• It must be reachable and reliable around the clock - downtime means missed mail.
• Other mail systems must trust yours, which requires careful setup.
• Spam and security are a constant, ongoing effort, not a one-time task.
• If it breaks, the fix is on you - there is no support line to a mail provider.

MailPlus Server vs. the Web Client

MailPlus comes in two parts, and it helps to know the difference. One is the engine; the other is the window you read your mail through.

MailPlus Server is the heavy machinery working in the background. You set it up once, carefully, and it does the actual job of being a mail server. The MailPlus client is the friendly inbox you look at day to day - a bit like the webmail screen you may already know.

Synology Calendar

This is the friendliest place to begin. Synology Calendar looks and works much like the calendars you already know, but every appointment lives on your NAS instead of a big company's servers.

Because it plays by standard rules, you can often view and add events from the built-in calendar on your iPhone, iPad, or computer, not only from the Synology screen. That makes it comfortable to adopt.

• Create appointments, reminders, and all-day events.
• Keep several calendars - say, one for work and one for family.
• Share a calendar with others, so a team or household can see the same schedule.
• It uses a common calendar standard, so it can sync with the calendar app on your phone or computer.

Note Station - Notes and Notebooks

Note Station is Synology's note-taking app. Think of it as a private notebook that lives on your NAS - a place for lists, ideas, meeting notes, recipes, whatever you like to jot down.

If you have used other note apps, this will feel familiar. The difference, again, is ownership - your notes are stored on your own equipment, not on an outside service that could change its terms or read your content.

• Organize notes into notebooks, much like folders for your thoughts.
• Add pictures, attachments, and simple formatting to a note.
• Search across everything to find that note from months ago.
• Share a note or notebook with someone you choose.

Synology Office - Documents, Sheets, Slides

Synology Office lets you create documents, spreadsheets, and slide presentations right in your web browser, with everything saved on your NAS. If you have used online office tools, the idea will be familiar.

Several people can work on the same document at once, and it can open and save common file types, so you can trade files with folks using other office programs. It builds on Synology Drive, which handles the syncing and sharing behind the scenes.

• Document - for letters, reports, and any writing.
• Spreadsheet - for budgets, lists, and figures.
• Slides - for presentations.

Synology Contacts

Synology Contacts is an address book that lives on your NAS. It keeps names, numbers, and email addresses in one private place, and it ties in with the rest of the suite.

For a household it may be a nice extra. For a small business, a shared, private contact list that everyone can reach - without handing it to an outside service - can be genuinely useful.

• Store and organize your contacts on your own equipment.
• Share address books within a team or family.
• It uses a common contacts standard, so it can sync with the contacts app on your phone or computer.
• It works hand in hand with MailPlus and Calendar - handy when you address an email or invite someone to an event.

Synology Chat

Synology Chat is a private messaging app for a team, run on your own NAS. If you have used workplace chat tools, it fills the same role - quick messages and channels - but the conversations stay on your equipment.

This one is aimed at small businesses and organizations more than households. If a handful of coworkers want a private place to talk without an outside service, Chat does the job.

• Send direct messages and create group channels by topic.
• Share files right in the conversation.
• Keep the whole team's chat history private, on your NAS.
• Use it from a browser or a mobile app.

Who This Suite Is a Good Fit For

Self-hosting an office suite is not for everyone, and that is fine. Here is who tends to get the most out of it, so you can see where you land.

• Value privacy and want your data on your own hardware.
• Already own a Synology NAS and want more from it.
• Run a small business or organization and want in-house tools.
• Are comfortable trying new apps, or have someone to help you.
• Want to reduce monthly software subscriptions over time.

Who Should NOT Self-Host Email

I said I would be honest, so here it is plainly. Most people should not run their own email server. The easy apps in this suite are a joy. Email is a different animal, and it bites the unprepared.

• Deliverability. Getting other mail systems to trust yours - so your mail does not vanish into junk folders - takes careful, technical setup.
• Spam. The moment a server faces the internet, spam and attacks arrive. Fighting them is constant work.
• Reputation. If your setup slips, big providers may quietly block your mail, and undoing that is slow and painful.
• No safety net. When email breaks, there is no provider to call. It is all on you.

Licenses - Free and Paid Accounts

Most of the suite is free to use once you own the NAS. MailPlus is the exception: it includes a number of free email accounts, and if you need more, you buy licenses for them.

For a household or a very small operation, the included free accounts are often plenty. It is worth checking the current free count on Synology's site, since the exact number can vary.

• MailPlus Server comes with a set number of free email accounts to start.
• If you need more accounts than that, you purchase additional license packs from Synology.
• The licenses are a one-time purchase, not a monthly fee, and they do not expire.
• The other apps - Calendar, Notes, Office, Contacts, Chat - do not need these mail licenses.

Backing Up These Apps' Data

Here is the part people forget. When you self-host, your data lives on your NAS - which means if the NAS is lost, so is everything, unless you have a backup. This matters more here than anywhere else in the suite.

• Your calendars, notes, documents, contacts, chat history, and mail.
• In short, the data behind every app you rely on.

Mobile Access to the Suite

You are not tied to a desk. Synology makes phone and tablet apps for much of the suite, so you can check your calendar or jot a note from anywhere.

There is also Synology Contacts, which can sync to your phone's own contacts using standard settings. To reach your NAS from outside the house, you set up secure remote access first - a good thing to have me help with the first time.

How It Compares to Microsoft 365 and Google Workspace

It is fair to ask how this stacks up against the big commercial suites. The honest answer: it trades polish and hands-off convenience for privacy, ownership, and lower ongoing cost.

Neither is simply better. If you want zero maintenance and the deepest features, the big suites are hard to beat. If you want your data on your own hardware and fewer monthly bills, the Synology suite is compelling - especially for the non-email apps.

A Gentle Way to Start

If any of this appeals to you, do not try to switch everything at once. Ease in with the safest apps, build confidence, and only then consider the harder pieces. Here is the order I suggest.

By the time you have used Calendar and Notes for a while, you will know whether self-hosting suits you, without having risked anything important.

• Install Synology Calendar and set up one shared calendar. Live with it a week.
• Add Note Station and move a few notes over. See how the phone app feels.
• Try Synology Office or Drive for a document or two, especially if sharing with others.
• Add Contacts and Chat only if you have a clear need for them.
• Consider MailPlus LAST, and only if you truly have the know-how - or professional help.

The Privacy Upside

For many people, privacy is the real reason to do any of this. When your calendar, notes, and files live on your own NAS, no outside company is reading them, scanning them, or profiting from them.

This matters especially for a small business handling client information, or anyone who simply prefers their private life stay private. Ownership of your data is a real, concrete benefit - not just a nice idea.

• Your notes and documents are not scanned to target advertising.
• Your data is not tangled up in a big company's terms of service or data policies.
• You decide who has access, and you can revoke it.
• Your information does not sit on servers in places you cannot see or control.

A Getting-Started Checklist

Here is the whole approach as one checklist. Work down it in order, and you will adopt the suite the calm, low-risk way.

• Decide what you actually want - calendar, notes, files, or more.
• Make sure your NAS backups are running before you rely on any app.
• Install Synology Calendar from Package Center and set up one calendar.
• Add Note Station and move a few notes over.
• Install the matching phone apps so you can use them on the go.
• Set up secure remote access if you need to reach the NAS from away.
