(Answer required) Configuring the .env File

The Nextcloud Exchange Connector is entirely configuration-driven. This reference guide explains every parameter available to customize the synchronization behavior, performance limits, and connectivity of your application.

Warning: Strict File Naming

Your configuration file must be named exactly “.env” (an empty filename with an .env extension). Naming the file settings.env or anything else will cause the application to fail to read the configuration.

Warning: Escaping Special Characters in Docker

When configuring passwords, connection strings, or secrets in your .env file, be aware of Docker's character constraints. Specifically, the dollar sign $) is reserved for variable interpolation. If your actual password contains a literal $, you must escape it by doubling the character (e.g., a password of Pa$word must be written as Pa$$word in the .env file).

Failure to escape this will cause Docker to drop the character, resulting in severe authentication errors.

Tip: This configuration guide is extensive. To quickly find a specific parameter from your .env file, use your browser's search function (Ctrl + F or Cmd + F) and enter the variable name.

Configuration Strategy: Minimal vs. Full

To simplify deployments, it is recommended to build your .env file based on your needs:

Minimal Config for Docker deployment (Single Instance)
Full Config for Docker deployment (Multi-Instance)
Minimal Config for Binary deployment (Single Instance)
Full Config for Binary deployment (Multi-Instance)

Configuration Reference

Service Configuration

These settings control the core behavior, identification, and scheduling of the synchronization instances.

Parameter	Meaning & Usage	Example	Applies To
`Service__IsPrimary`	Meaning: Dictates if this instance is the primary synchronization coordinator. Usage: Exactly one instance must be set to `true`. All secondary replicas or workers must be `false`.	`true`	Docker, Binary
`Service__DeploymentType`	Meaning: Specifies the hosting method. Usage: Set to `0` for Docker or `1` for Binary deployments.	`0`	Docker, Binary
`Service__AspNetCoreUrl`	Meaning: The internal port and URL for the application. Usage: Must be unique for every instance running on the same host to prevent port collisions.	`http://localhost:5001`	Binary
`Service__DefaultWorkerName`	Meaning: The unique identifier for the instance. Usage: Used in logs and database tracking to identify which worker processed a task.	`"SendentWorker-1"`	Docker, Binary
`Service__BatchLimit`	Meaning: Maximum number of elements per EWS request. Usage: Prevents overloading the Exchange server with excessively large single payloads.	`50`	Docker, Binary
`Service__WorkerIntervalSeconds`	Meaning: The sleep interval between global application runs. Usage: Determines how often the application checks the database for new users to process.	`120`	Docker, Binary
`Service__SyncIntervalInSeconds`	Meaning: The standard cooldown delay before a specific user is scheduled for their next sync. Usage: Prevents continuous looping on the same user.	`60`	Docker, Binary
`Service__CriticalSyncIntervalInSeconds`	Meaning: The retry delay for users whose synchronization failed. Usage: Gives the system time to recover before retrying a broken sync.	`100`	Docker, Binary
`Service__BatchSaveSize`	Meaning: Database transaction chunk size. Usage: Maximum number of objects saved to the database in a single transaction.	`100`	Docker, Binary
`Service__StartWeekend`	Meaning: Defines the day that marks the start of the weekend. Usage: Used in calendar logic (1 = Monday, 6 = Saturday, 7 = Sunday).	`6`	Docker, Binary
`Service__SyncMode`	Meaning: Declares which data entities are synchronized. Usage: Bitwise value (`1`=Calendars, `2`=Contacts, `4`=Tasks). Sum them up to combine (e.g., `3` for Calendars + Contacts).	`1`	Docker, Binary
`Service__SyncType`	Meaning: Level of detail for synchronization. Usage: Set to `0` for Full sync (all data), or `1` for Sensitive sync (hides confidential details). — TO CHECK WITH LUC WHAT IS SENSITIVE	`1`	Docker, Binary

Database Configuration

These settings connect the application to your storage backend.

Parameter	Meaning & Usage	Example	Applies To
`DatabaseConfiguration__DatabaseType`	Meaning: Selects the database provider. Usage: `0`=Postgres, `1`=SqlServer, `2`=MariaDB, `3`=MySql.	`0`	Docker, Binary
`DatabaseConfiguration__DatabaseEncryptionKey`	Meaning: Secret key for encrypting sensitive data. Usage: Used to encrypt Nextcloud app-tokens stored in the database.	`YourSuperSecretKey123!`	Docker, Binary
`DatabaseConfiguration__ConnectionString`	Meaning: The connection string to reach the database. Usage: Format strictly depends on your chosen database provider.	`Host=postgres_db;Port=5432;...`	Docker, Binary

Nextcloud Configuration

These settings connect the application to the Nextcloud frontend.

Warning: Shared Secret Mismatch

Your Service__NextcloudConfiguration__SharedSecret value must exactly match the shared secret generated in the Sendent Sync app within your Nextcloud web interface.

Parameter	Meaning & Usage	Example	Applies To
`Service__NextcloudConfiguration__NextcloudBaseUrl`	Meaning: The Base URL of your Nextcloud instance. Usage: Must include the protocol (http/https).	`https://cloud.example.com/`	Docker, Binary
`Service__NextcloudConfiguration__NextcloudServiceUsername`	Meaning: Username of the Nextcloud service account. Usage: Used to authenticate API calls to Nextcloud.	`serviceAdmin`	Docker, Binary
`Service__NextcloudConfiguration__NextcloudServicePassword`	Meaning: Password of the Nextcloud service account. Usage: Plaintext password or app-password for the admin.	`SecurePass123`	Docker, Binary
`Service__NextcloudConfiguration__SharedSecret`	Meaning: Cryptographic shared secret. Usage: Used to securely transfer user consent tokens from Nextcloud to the connector.	`"my_secure_secret"`	Docker, Binary

Exchange Server Configuration

These settings define how the application authenticates and connects to Microsoft Exchange.

Warning: Avoid Raw Exchange Credentials

We strongly discourage using the Service__ExchangeConfiguration__ExchangeAdminRaw parameter. Escaping quotes and slashes within the .env file breaks the parser. Always use the ExchangeAdminFile approach.

Parameter	Meaning & Usage	Example	Applies To
`Service__ExchangeConfiguration__ExchangeType`	Meaning: Selects the Exchange environment architecture. Usage: `1`=Cloud (M365), `2`=OnPremKerberos, `3`=OnPremBasicAuth, `4`=OnPremADFS.	`1`	Docker, Binary
`Service__ExchangeConfiguration__ExchangeOnPremUrl`	Meaning: The EWS endpoint URL. Usage: Required for all Exchange connections to process Web Services calls.	`https://exchange.example.com/EWS/Exchange.asmx`	Docker, Binary
`Service__ExchangeConfiguration__ExchangeOnPremDomain`	Meaning: The domain name for Exchange. Usage: Required for OnPrem Kerberos and BasicAuth types.	`domain_test`	Docker, Binary
`Service__ExchangeConfiguration__ExchangeOnPremAdfsAuthorityUrl`	Meaning: The ADFS authority URL. Usage: Required only if using the OnPremADFS connection type.	`https://adfs.example.com/adfs`	Docker, Binary
`Service__ExchangeConfiguration__ExchangeTenantId`	Meaning: Microsoft Tenant ID. Usage: Required only if using Cloud (M365) connection type.	`xxxx-xxxx-xxxx-xxxx`	Docker, Binary
`Service__ExchangeConfiguration__ExchangeAdminFile`	Meaning: Path to your JSON file containing Exchange service accounts. Usage: You can point to subfolders (e.g., `prod/admins.json`) to easily switch environments.	`admins.json` `prod/admins.json` `test/admins.json`	Docker, Binary

Concurrency Configuration

These settings control the application's throughput and scaling behavior.

Parameter	Meaning & Usage	Example	Applies To
`Service__ConcurrencyConfiguration__MaxParallelProcessingUsers`	Meaning: Global limit of concurrent users processed per instance. Usage: Prevents a single worker node from running out of RAM.	`10`	Docker, Binary
`Service__ConcurrencyConfiguration__MaxUsersPerAdmin`	Meaning: Maximum users processed concurrently by a single Exchange service account. Usage: Prevents Microsoft Exchange from throttling your connections.	`10`	Docker, Binary
`Secondary_Replicas_Amount`	Meaning: The number of secondary containers to deploy automatically. Usage: Scales your synchronization power. Ignored in Binary deployments.	`2`	Docker

Specific Synchronization Configurations

Parameter	Meaning & Usage	Example	Applies To
`Service__FullSyncConfiguration__ProcessAttachments`	Meaning: Allows or disallows processing of attachments. Usage: Applicable only when `Service__SyncType=0` (Full Sync).	`true`	Docker, Binary
`Service__SensitiveSyncConfiguration__SensitiveTitle`	Meaning: Custom title applied to events in Exchange. Usage: Hides meeting details when `Service__SyncType=1` (Sensitive Sync).	`"Busy"`	Docker, Binary
