Changing the working hours on a room mailbox in Outlook/Exchange

mk flag

I setup a Room resource recipient in Exchange so that users could book the associated conference room. This part works, but when I attempt to view the room's schedule in Scheduling Assistant, the room shows as Out of Office for regular working hours.

I've tried searching for a solution to this problem and found this other question, but the room does not appear in Recipient Mailboxes, but Recipient Resources and therefore has different settings than those described. I have not found any way to configure working hours for the room in the resource settings, either. How can I either align the Out of Office hours for the room with the rest of the team, or else remove them entirely?

By default, working hours of resource mailboxes are 8:00 A.M. to 5:00 P.M. Monday through Friday.

You can refer to this command to check the working hours of this resource mailbox:

get-MailboxCalendarConfiguration -Identity <PrimartySMTPofRoomResource> |select-object WorkingHours*

If the working hours for this mailbox is incorrect, you can run the following command to change the time:

Set-MailboxCalendarConfiguration -Identity <PrimartySMTPofRoomResource>
-WorkingHoursStartTime 08:00:00 -WorkingHoursEndTime 17:00:00

Thanks for the answer. Are you aware if there's a package I have to install to have access to these commands? They don't seem to be present on my installation of PowerShell.

Yes. You need to install the ExchangeOnlineManagement module and connect to Exchange Online PowerShell with Global Administrator or Exchange Administrator. For specific information, you could refer to the following links: [About the Exchange Online PowerShell V2 module and V3 module | Microsoft Learn](https://learn.microsoft.com/en-us/powershell/exchange/exchange-online-powershell-v2?view=exchange-ps) [Connect to Exchange Online Protection PowerShell | Microsoft Learn](https://learn.microsoft.com/en-us/powershell/exchange/connect-to-exchange-online-protection-powershell?view=exchange-ps)

Looking at the module, I don't see either of the commands you mentioned in there.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
