Based on my audit for a client I found that a user mailbox was at sometime converted to a resource mailbox. There is no convert button/ link to switch it back. I still don’t know how, or why this would have happened.
Anyways, for someone who may come across this weird issue, here is the fix for it.

Set-Mailbox user@domain.com -Type Regular |
This will convert it from a shared mailbox, or a resource mailbox to a user mailbox.
By default Office365 limits Resource booking days to just 180 days. The maximum days it can be booked for 1080 days.
I like to make resource booking days 1 year from the day of making the reservation/ appointment. Now instead of visiting each calendar and making the change, powershell can help us out.

#Connect to Office365 $cred = Get-Credential Import-Module MSOnline Connect-MsolService -Credential $cred $s = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell -Credential $cred -Authentication Basic -AllowRedirection $importresults = Import-PSSession $s #Get all the Rooms and make the booking days to 365 Get-MailBox | Where {$_.ResourceType -eq "Room"} | Set-CalendarProcessing -BookingWindowInDays 365 |
Happy Booking!
If we want to check the detail information of the room mailbox schedule or change the permission level of the Calendar permission. We should do the following steps:
Assign Permission Add-MailboxPermission -Identity “[email protected]” -User “[email protected]” -AccessRights Fullaccess -InheritanceType All
On the Client Side the user will be able to the see the only if they have permissions. If no permissions are assigned it will give a warning saying it is unable to connect. This will go away once the permissions are set right!
