  1. Find “Settings” then navigate to “Accounts.”
  2. Select "Add Account."
  3. Select "Advanced" or "Manual Setup" on some devices.
  4. Select "Microsoft Exchange ActiveSync" from the drop-down menu.
  5. Set the following settings and values:
Setting Value
Description: Kolab Now, or anything of your choosing
Domain: The domain part of your email address
Username: Your full email address
Password: The password for your account
Server: Address apps.kolabnow.com
Port: 443
Use SSL: On

Keep in mind that there should be support for TLS 1.1 and later in the mail client.

POP3 vs. IMAP: What's The Difference

POP3 and IMAP are two different ways to set up a mailbox in an email client. Both are Message Accessing Agents, or MAA, which means you may access your mail account with a client application.

Using POP, you can download your emails from the mail server of your service provider and mark them for deletion from that point forth. This option implies that you will only be able to view these emails in the mail client and on that device. To access previously downloaded emails, you will need to use a separate client application on a different device or through webmail.

You cannot access emails sent via POP in any other email client than the one from which they sent since POP does not sync folders. Mail will not show up in the mailbox on the server and in other mail clients.

IMAP, or Internet Message Access Protocol, was created to overcome the limitations of POP.

IMAP enables you to access your emails from any client and on any device and sign in to webmail at any time until they get deleted. You will always see the same emails no matter how you visit your provider's server.

Because your emails are kept on the provider's server rather than locally when using IMAP, you may run into mail storage constraints.

Finally, if you view a message on a single device and do not have continuous active internet access, POP might be your protocol. However, IMAP might be the way to go if you have many mailboxes and do not need to keep track of emails on a single device.
