I. Intro

Company administrators can standardize one-way syncing of Lark and Exchange calendars for all members via the admin console. After the calendar data is synced, members can view and edit Exchange events in Lark. Updated new event information will be synced to their Exchange calendars in real time.

Note: Aside from the Exchange Calender, this function also supports Exchange on-premise, Exchange Online, Outlook, and Hotmail, Live, and MSN Calendar syncing. Please upgrade your client to V5.2 or later to ensure events aren't repeated.

II. Steps

1. Configure your Exchange administrator account

•Go to Settings > Data Migration > Exchange Calendar sync > New administrator account.

Note: Administrators need to configure their impersonation permission on Exchange. 30 minutes after the configurations are completed, administrators can proceed with the steps listed below.

•Select a communication protocol with the email server and enter your Exchange administrator account and password. If all information entered is correct, click Next.

2. Pair syncing accounts

2.1 Upload an account template

•Download a blank import template. Batch enter all user information, then upload the table. You can use Click here to upload table or drag and drop files to the upload area. Once the upload is successful, click Next.

2.2 Confirm account pairing status

•If the member's Lark account is associated with their Exchange account already, then the system will automatically match the accounts. Administrators can edit Lark account information that's already been paired and manually pair accounts that haven't been matched.

•The system will list out the number of accounts successfully matched and failed to match. Administrators can use the filter function to confirm pairing status. Once that's done, click Start syncing.

•Confirm all account information synced is correct. Click Close to complete the sync.

•To import more accounts, click New Syncing Task to return to the account template uploading page and continue syncing.

3. View and edit sync details

3.1 View sync status

•On the Exchange Calendar sync page, administrators can view configured Exchange administrator accounts, sync status, and sync direction. If Connected is displayed, then that means all user calendars under that Exchange administrator account are syncing normally.

3.2 Change sync direction

•Click the ... icon on the far-right and select Change sync direction to change a configured administrator account's sync direction.

Note: When changing sync directions from one-way to two-way, if the system detects that a Lark account is associated with multiple Exchange accounts, then the administrator must re-confirm the account's pairing status to continue syncing.

3.3 Stop syncing

•Click the ... icon and select Stop syncing to pause the calendar data syncing that's under an Exchange administrator's account. The pairing status will be kept and can be re-synced when needed.

3.4 Unpair accounts

•Click the ... icon and select Unpair account. Member's Exchange Calendar that is under the selected administrator will no longer be displayed in Lark Calendar. The pairing will also be deleted and can't be re-synced.

4. After one-way syncing

•Launch the Lark client. In the lower-left of Calendar, the synced Exchange Calendar events will be displayed, including personally created events and events invited by other Exchange users. Click the Exchange event to view event details, including participants, location, and the specific meeting room.

III. FAQs

Will the Exchange accounts of new members be automatically synced?

No. Administrators will have to pair the accounts to sync them or use an Open API to automate the syncing.

Why did the system prompt that the user's calendar has already been synced?

That may happen if the member configured calendar syncing on their own, or if another administrator has already paired that member's calendar data. If it's the latter, then the administrator can delete the initially configured administrator account and re-sync members' calendar data in a new administrator account.
