You and your substitutes can maintain your calendar either in the SAP system or in Microsoft Outlook using Outlook calendar integration. So that both calendars stay up to date, they are regularly compared. Your individual settings determine when the synchronization process starts and whether the user receives queries concerning the process.
In the Outlook calendar, you can execute the available functions independently of SAP and work online or offline. If you require help when working with the Outlook calendar, call Microsoft help. If you require help with regard to synchronization, see Synchronizing SAP Calendars and Outlook Calendars.
Make sure that you work in Outlook in the calendar file that you set in the calendar profile. If you also want to maintain another calendar as a substitute, you have to create a calendar profile for this calendar too. Only the calendar specified in the current profile is synchronized.
