Hi Kelly
Thanks for the feedback.
After looking into your issue further, I found that when a booking page in Microsoft bookings is created a scheduling mailbox is created, this mail box is not shown in the Exchange admin center but Exchange Online PowerShell can be used to set a new mailbox.
Firstly you have to connect Powershell to Exchange online for detailed steps on how to do so kindly see the steps in Connect to Exchange Online PowerShell | Microsoft Docs
Once you've connected your Exchange Online to Powershell, run the following commands:
Get-Mailbox -RecipientTypeDetails SchedulingMailbox -ResultSize:Unlimited | Get-MailboxPermission |Select-Object Identity,User,AccessRights | Where-Object {($_.user -like '*@*')} , this command can be used to retrieve information of all bookings mailboxes and users who have access to them.
Then run Set-mailbox- identity< insert your alias> -EmailAddresses <insert your email address>
Then after Get-Mailbox-RecipientTypeDetails SchedulingMailbox | Select-object DisplayName,Alias,PrimarySMTPAddress.
Please feel free to let me know how it goes.
Regards
Momo.
