Mail and calendar apps

You can read and send your Kantoor mail, and see your calendars, tasks and contacts, in the apps you already use: on a phone, a tablet or a computer. Everything stays in step with Kantoor in the browser.

Before you start

1. Create an app password for the device. Keep IMAP, SMTP and DAV ticked.
2. Have your e-mail address at hand. It is the user name everywhere.

Use the app password, not the password of your Shiloh account.

The settings

What	Setting
Incoming mail (IMAP)	Server kantoor.shilohbv.com, port 993, security SSL/TLS
Outgoing mail (SMTP)	Server kantoor.shilohbv.com, port 465, security SSL/TLS, authentication normal password
Incoming mail (POP3), only if your app cannot use IMAP	Server kantoor.shilohbv.com, port 995, security SSL/TLS
Calendars and tasks (CalDAV)	Server https://kantoor.shilohbv.com/dav/ (some apps want only kantoor.shilohbv.com)
Contacts (CardDAV)	Server https://kantoor.shilohbv.com/dav/
User name	Your full e-mail address, for example femke@example.com
Password	The app password

These were checked on 14 November 2026: the mail ports 993, 995 and 465 answer with a valid certificate for kantoor.shilohbv.com. Ports 143, 110 and 587 (unencrypted or STARTTLS) are not offered: choose SSL/TLS.

Note

POP3 shows only the inbox, and by default leaves your mail on the server. Use IMAP when you can: then every device sees the same folders and the same read marks.

Sent mail: Kantoor does not put a copy of mail sent from an app in Sent; most apps do that themselves (in the app’s account settings: “Place a copy in Sent”).

Automatic set-up

Many apps fill in the settings themselves when you type your e-mail address. This works when your domain has the discovery records described in DNS records. If the app does not find the settings, enter them by hand with the table above.

Thunderbird (Windows, macOS, Linux)

Mail

1. Open Account Settings and choose Account Actions, Add Mail Account.
2. Fill in your name, your e-mail address and the app password, and choose Continue.
3. If Thunderbird finds IMAP kantoor.shilohbv.com 993 SSL/TLS and SMTP kantoor.shilohbv.com 465 SSL/TLS, choose Done. Otherwise choose Configure manually and enter those values, with authentication Normal password and your full e-mail address as user name.

Calendar and tasks

1. In the calendar, choose New Calendar, On the Network.
2. Fill in your e-mail address as user name and https://kantoor.shilohbv.com/dav/ as location, and choose Find Calendars.
3. Enter the app password. Tick the calendars and task lists you want.

Contacts

1. In the address book, choose New Address Book, Add CardDAV Address Book.
2. User name: your e-mail address; location: https://kantoor.shilohbv.com/dav/.
3. Enter the app password and choose the address book.

iPhone and iPad

The quickest way is the Apple profile, which sets up mail, calendar and contacts at once:

1. On the iPhone or iPad, open Kantoor in Safari, sign in, and open Settings, App passwords.
2. Create an app password and copy it.
3. Choose Download an Apple profile, and allow the download.
4. Open the iPhone Settings app. Choose Profile Downloaded near the top, then Install. The device says the profile is “Not Signed”; that is expected.
5. When asked, paste the app password.

The profile contains no password; it only fills in the server settings.

By hand: Settings, Mail, Accounts, Add Account, Other:

• Add Mail Account: name, e-mail address, app password, description. Choose IMAP. Incoming and outgoing host kantoor.shilohbv.com, user name your e-mail address, password the app password. The iPhone uses SSL by itself; check under the account’s Advanced settings that the incoming port is 993 and the outgoing port 465 with SSL.
• Add CalDAV Account: server kantoor.shilohbv.com, user name, app password.
• Add CardDAV Account: the same.

Mac (Mail, Calendar, Contacts)

Use the same Apple profile: download it on the Mac and install it in System Settings, Privacy & Security, Profiles (on older macOS: System Preferences, Profiles).

By hand: System Settings, Internet Accounts, Add Other Account: Mail Account for mail (the IMAP and SMTP values above), CalDAV account and CardDAV account with account type Manual, user name, app password and server https://kantoor.shilohbv.com/dav/.

Android

Android has no built-in CalDAV or CardDAV. Use:

• Mail: an app such as K-9 Mail (Thunderbird for Android) or FairEmail, with the IMAP and SMTP values above;
• Calendars, tasks and contacts: the app DAVx⁵. Choose Login with URL and user name, base URL https://kantoor.shilohbv.com/dav/, user name your e-mail address, password the app password. DAVx⁵ shows each calendar, task list and address book; switch on the ones you want. They then appear in the phone’s own calendar and contacts apps. For tasks, install a task app that works with DAVx⁵, such as jtx Board or Tasks.org.

Outlook

Outlook may find the settings by itself; this depends on the version, and has not been tried with a real Outlook yet. If it does not, add the account by hand:

1. File, Add Account, type your e-mail address, open Advanced options and tick Let me set up my account manually.
2. Choose IMAP.
3. Incoming mail: kantoor.shilohbv.com, port 993, encryption SSL/TLS. Outgoing mail: kantoor.shilohbv.com, port 465, encryption SSL/TLS.
4. Enter the app password.

Outlook for Windows does not support CalDAV and CardDAV. To see your Kantoor calendar there, use the browser, or a CalDAV add-in.

GNOME Evolution (Linux)

1. File, New, Collection Account. Fill in your e-mail address, tick that the user name is your e-mail address, and choose Look up.
2. Evolution finds the mail settings, the calendars, the task list and the address book. Enter the app password when asked.

By hand: a Mail Account with the IMAP and SMTP values above, and calendars, task lists and address books of type CalDAV and CardDAV with the URL https://kantoor.shilohbv.com/dav/.

What we tried

Checked against the live service with real software: GNOME Evolution’s set-up, vdirsyncer (calendars and contacts) and mbsync (mail). The steps for Thunderbird, DAVx⁵, iPhone, Mac, Android mail apps and Outlook follow the documentation of those apps and were not all tried on a device. If a step does not match what you see, tell us.

Problems connecting

What you see	What to do
The app says the password is wrong	Use the app password, not your Shiloh account password. Check the user name is your full e-mail address. Check in Settings, App passwords that the password is active and has the scope the app needs.
The app says the certificate is wrong	You typed another server name. Use kantoor.shilohbv.com exactly.
Mail arrives but sending fails	The app password needs SMTP ticked. Use port 465 with SSL/TLS, not 587.
Calendars do not appear	The app password needs DAV ticked. Use https://kantoor.shilohbv.com/dav/ with the slash at the end.
After many wrong tries the app cannot connect at all	Kantoor slows down repeated failed logins. Wait a few minutes, then try with the right password.
