| Description | <USER> created a new restricted view on folder Calendar. |
| Event Information | When you import a CAL file using a Microsoft Outlook client and you select either Replace Duplicates With Items Imported or Do Not Import Duplicate Items, the import process becomes progressively slower as each appointment is processed in the CAL file, and the information store CPU utilization gradually increases. After the import process is complete, the Outlook client will observe slow calendar operations (slow to create or modify appointments, and reminder notifications are slow to appear). CAUSE: The Outlook client is using an inefficient process during the CAL file import to determine when duplicate items exist. This causes the information store to create structures in the database that impact the performance of operations involving the Calendar folder. |
