How to remove 1440 minute meeting duration limit?

Question

Hi all

I'm using microsoft graph api to create an event in a room of ours (POST https://graph.microsoft.com/v1.0/me/events). When creating an event with duration less than 24 hours everything works fine but when it lasts more then a day the meeting gets declined by the room with this message:

Is there a way to remove this 1 day barrier? Sometimes the room needs to be booked for multiple days.

Thanks.

Set the maximum duration to 0, or whichever value you want:

Set-CalendarProcessing roomname -MaximumDurationInMinutes 0

Hi @Lenny Puente

Yes, like michev suggest above, the MaximumDurationInMinutes parameter specifies the maximum duration in minutes for meeting requests. A valid value is an integer from 0 through INT32 (2147483647). The default value is 1440 (24 hours).

You could use the command above to set for one specific mailbox, or setting for all room mailboxes in your organization

Get-Mailbox | where {$_.recipientTypeDetails -eq "roomMailbox"} | Set-CalendarProcessing -MaximumDurationInMinutes 14400
