5.1. Related to Incoming Server:

The IMAP accounts are synchronizing all mail folders between Outlook 2016 and the mail server. You can manage the sync frequency by clicking on the Advanced button. This will open the Server settings box, where you can change the Sync all IMAP folders period. By default, it is set to 2 minutes

4. Click Add Account.

5. When you have successfully added the email account, it will appear in the top left pane of the Accounts box. Outlook will also begin downloading your emails. The following additional settings steps 5.1 and 5.2 are optional.

5.1 Related to the Incoming Server:

The POP accounts have the option to Leave a copy of the message on the server. This option is enabled by default in Outlook 2016. If you disable it (not recommended), Outlook will delete your email messages from the server while downloading to your Inbox folder. Therefore, you will not see them in the Open-Xchange webmail.

Note: If you setup your mailbox as an IMAP account, emails are synced on your computer. All messages remain on the mail server until you delete them.

After you add your POP account, you can manage the Leave a copy of the message on the server option by clicking on the Advanced button. This will open the Server settings box.

5.2 Related to the Outgoing Server:

For security reasons, our outgoing (SMTP) server requires authentication. By default, Outlook 2016 will automatically configure your outgoing server to use your incoming server credentials. In order to make sure that the outgoing server settings are properly configured, click the More Options button and verify that you are using the setting below:
