Using Classic Outlook on Windows for personal email, calendar, and contact management
Hello Melissa,
By default, the published Office 365 calendar will show events for 6 months. If you want to change the value to a longer period, please contact your Office 365 admins and run the following PowerShell commands:
- Connect to Exchange Online PowerShell.
- Run the following command:
**Set-MailboxCalendarFolder -Identity ****@domain.com:\Calendar –PublishEnabled $true -PublishDateRangeFrom SixMonths -PublishDateRangeTo OneYear
You can see this article for reference: Set-MailboxCalendarFolder.
If you have any questions, please feel free to contact us.
Regards,
Rick
