How can I synchronize my calendar with Google, Outlook, Exchange etc.?

← First Setup
When it comes to sync, you can establish it two ways: your app will either use the built-in Android sync function (this applies to most of the apps and devices) or you can rely on the app’s own sync functions. In the case of Business Calendar you can actually use both.

When you successfully have entered the account information, your device/Business Calendar are ready to communicate with the newly added account. Here’s how to proceed: 

Android Sync

Here, Business Calendar is using the Android calendar database and the built-in synchronization functionality of the Android operating system to sync with supported partners, i.e. Google or Microsoft Outlook. Therefore you have to establish the sync with these partners in the Android system settings first. This means all events that have been created using Business Calendar can also be viewed with any other calendar application, that is accessing the Android calendar database (e.g. the stock calendar app) and vice versa. Please also remember, that the layout of the system settings may vary on different devices.


1. Open the → Android system settings, scroll down to the menu item → Accounts and click on it




2. Click on → Add account




3. Choose the account type you want to add (e.g. Google as highlighted in the screenshot below)




4. Enter the account information to set up your account. For Google accounts you can also create a new one here



To synchronize with another account type just choose your favorite one similar to screenshot #3. If the desired account type is not available on your device, it may be possible that you have to install the corresponding application first. Note that certain account types (e.g. DAV sync) may require a third-part app to perform the sync process.

Hint 1: If you already added the account for sync and experience some problems syncing the calendar, please verify if your Android Stock Calendar has the same issue. If yes, it might be a general sync error and it might help to remove and re-add the affected account to your device. You can also follow the article here.

Hint 2: If your account is set up correctly and you still are not able to sync, please verify if the calendar sync is enabled in the Google/Microsoft/other account settings. If not, enable it with the icon provided. If you don't see the option at all , you will have to install the Google Calendar app on some devices.

Own sync

Some devices, such as Huawei degoogled devices, don’t provide the built-in sync functions and this is where we needed to establish, you can still access your calendars. The other reason for using the app’s built-in sync, is the ability to go around the Android sync limitations. Furthermore, you can sync where Android reaches its limits e.g. Outlook color categories.

In such a case you log your account in the app and the app itself takes over the sync process. We made sure that the process is straightforward and easy:

1.You start with opening the app and side menu


2. Click on the → Calendars & Task lists
3. Click on the log-in icon in the action bar
4. Choose → Google and/or Microsoft account
5. Log in with your data

Once the account is set up, you can go to the settings → maintenance → calendars → periodic event synchronization and set a chosen sync interval for your calendars.

Hint 1: If you already added the account for sync and experience some problems syncing the calendar, please remove the affected account with the → “X” icon provided. Afterwards your log in again. This should trigger the proper sync. You can also follow the article here. If you have problems syncing an Outlook/Exchange account, you may also want to check this article.

Hint 2: If your account is set up correctly and you still are not able to sync, please verify if the calendar sync is enabled in the Business Calendar account settings. If not, enable it with the icon provided. You may also want to close the app and reopen it.
