# Product registration

Before you start using TrueConf Calendar Connector, you will need to register it according to the instructions below.

# Obtaining the registration key

During product registration, you will need your registration key, which you will receive after completing the form at the following link:

/docs/calendar-connector/media/reg_form/en.png

The registration key will be sent to the email address you provided when filling out the form.

The key should arrive within 15 minutes

If this doesn't happen, please contact us or check the SPAM folder of your email client.

# Online registration

When the software is registered online or if the free version of the product is used, access to the registration server reg.trueconf.com via the port 443 (TCP) will be needed.

# Windows

Open the command line (cmd) as an administrator and activate the software using the registration key:

C:\Program Files\TrueConf\Calendar\tc_calendar.exe --register MY-REG-KEY

where MY-REG-KEY is the activation key received after filling out the registration form.

After successful registration, you will see:

Your product successfully registered. Now you can run tc_calendar

# Linux

Execute the command:

sudo /opt/trueconf/calendar/bin/calendar/tc_calendar --register MY-REG-KEY

where MY-REG-KEY is the activation key received after filling out the registration form.

After successful registration, you will see:

Your product successfully registered. Now you can run tc_calendar

# Offline registration

A free license cannot be registered offline. This form of registration is available only for paid licenses.

The software has to be activated in offline mode in the networks that do not have access to the registration server reg.trueconf.com via the port 443 (TCP).

Check whether the software has access to reg.trueconf.com by running this command:

ping reg.trueconf.com

For offline activation:

If there is no connection to the registration server while executing the registration command, a regoffline.crg file will be generated as a result of the command, and the file path will be displayed in the terminal.
Send the regoffline.crg file to your manager in any convenient way.
In response, the manager will send you a valid registration file. Copy this file to the TrueConf Calendar Connector directory.

# Windows

Open the terminal (command line) as an administrator and activate the software with the help of the registration key:
```
  C:\Program Files\TrueConf\Calendar\tc_calendar.exe --offline_reg regoffline2.crg
```
Generate an encrypted password for the impersonation account by executing the command:
```
  C:\Program Files\TrueConf\Calendar\tc_calendar.exe --hash_pass <password>
```

# Linux

Open the terminal (command line) as an administrator and activate the software with the help of the registration key:
```
  sudo /opt/trueconf/calendar/bin/calendar/tc_calendar --offline_reg regoffline2.crg
```
Generate an encrypted password for the impersonation account by executing the command:
```
  sudo /opt/trueconf/calendar/bin/calendar/tc_calendar --hash_pass <password>
```

An impersonation account is a Microsoft Exchange service account given the ApplicationImpersonation role by the administrator. Impersonation allows the caller (in our case, TrueConf Calendar Connector) to act as a user account. This means that the caller can perform operations using the permissions associated with the impersonated account, instead of its own permissions. Such an account is used in scenarios where centralized mailbox management is needed, such as in support services or automated systems.

To proceed with launching the calendar, you need to configure the configuration file first. To learn how to do this, go to the Configuration section.

# How to start the calendar application

# Windows

Open the Task Manager (Ctrl + Shift + Esc).
Go to the section.
Locate the TrueConf Calendar service and restart it (or start it if it was stopped).
Set up integration on the TrueConf Server side.
In case of successful registration, the following message will be displayed:

Your product successfully registered offline. Now you can run tc_calendar

Further management of TrueConf Calendar Connector is done using the task scheduler.

# Linux

After specifying the required parameters described above, start TrueConf Calendar Connector with this command:

sudo systemctl start trueconf-calendar.service

If the launch limit is exceeded, run this command:

sudo systemctl reset-failed trueconf-calendar.service

Now you can test the functionality of the TrueConf Calendar Connector service (daemon) by performing the following steps:

sudo systemctl status trueconf-calendar.service

You will receive one of the responses:

active (running) – TrueConf Calendar Connector is working normally.

failed – TrueConf Calendar Connector is NOT working. In this case, try restarting the service using the command described above.

Further management of TrueConf Calendar Connector is carried out via the terminal.

In case of any issues, please contact our technical support.
