Office365 Maximum allowed minutes 1440

When you create a meeting schedule for number of days, you will see an error  "This resource doesn't accept meetings longer than 1440 minutes". By default the mailbox or room was set for a maximum limit of 1440 minutes.

Here's how you can disable this limit.

• Login to the Office 365 Administration Console
• In Microsoft Office 365 Exchange, click on Manage.
• In Manage My Orgnization, click the drop down arrow, and click on Select on Another User. This will prompt you to select the mailbox or room to manage.
• Select a Mailbox or Room, click OK.
• In Option, click on Settings.
• In Scheduling Options, un-check the "Limit meeting duration", then click on Save.

That's all. You can now schedule a meeting or reserve a room for number of days.

Hope this help you.
