Just about an hour ago, an occurrence of a particular Calendar event was accidentally deleted, which belonged to a Series event indeed. Some rescue methods were performed to reset it back but failed. After searching the Internet for relevant information, no useful result appeared. Most relevant pages and blogs were talking about the desktop version of Outlook, such as Outlook 2010, or even Outlook 365. Moreover, a folder named “Deleted Items” was referred but the user found nothing inside.
Considering creating the missing item could be complicated, the user began to modify the starting time of the Series event to test if the entire series of the Calendar events could be rearranged appropriately, and the test succeeded. The series got recreated after changing the starting time. However, it did not work if altering the ending time. Following this principle, the modification could be done twice with an erratum and its correction. As a practical result, it could be still available to improve. The user planned to raise a feature request to Microsoft to add such an enhancement improving user experience and productivity.
