Create bookingStaffMember also requires Add-MailboxPermission
I created an Entra application with the required Graph permissions to manage Bookings scheduling mailboxes so that I could update the staffing for a Bookings page that I'm not a staff member of. Using that application to request a Microsoft Graph access token, meant I had the required permissions to add a user account (that already had a Bookings license) as an "administrator" (role) for a Bookings page (Bookings business), to replace another person who was the previous Bookings page administrator, but who had since left. I used https://learn.microsoft.com/en-us/graph/api/bookingbusiness-post-staffmembers?view=graph-rest-1.0&tabs=powershell to do this. For the record, I was not able to do this using https://learn.microsoft.com/en-us/powershell/module/microsoft.graph.bookings/new-mgbookingbusinessstaffmember?view=graph-powershell-1.0 using Microsoft.Graph.Bookings module version 2.30.0, presumably because I am not a staff member with the Bookings "administrator" role for that particular Bookings page. However, the newly added user could not access that Bookings page at https://outlook.office.com/bookings/homepage until a further step had been completed (Error: "You don't have access to this booking page" shows instead). To ensure the new Bookings page administrator could access the Bookings page, I needed to add mailbox permissions, which I used https://learn.microsoft.com/en-us/powershell/module/exchangepowershell/add-mailboxpermission?view=exchange-ps for. I found that giving the new Bookings page administrator full access to the scheduling mailbox ensured they could access the Bookings page. Example using ExchangeOnlineManagement PowerShell module: Add-MailboxPermission -Identity email address removed for privacy reasons -User email address removed for privacy reasons -AccessRights FullAccess If there is a more efficient way for an system admin to add new staff to a Bookings page, please let me know - otherwise, hopefully this helps someone who gets stuck đ
Practical Graph: Analyzing External Meeting Participants for Teams Meetings
A reader asked if it's possible to analyze the external meeting participants for Teams online events. The information is available through the Events Graph API, and some PowerShell code written using the Graph PowerShell SDK quickly extracts events to analyze and determine the set of external domains meeting participants come from. https://practical365.com/external-meeting-participants-analysis/
Unable to whitelist quarantined emails
We have an email that is being constantly quarantined from a webform. The email comes from the email of the web form server, but is spoofing an internal address in our tenant by design. The email keeps getting blocked, and nothing we've tried as far as transport rules, whitelist additions, etc has been able to discernably affect this. There is a option to create a tenant allow list entry but the maximum duration is 45 days. We need a way to reliably whitelist an email indefinitely.Outlook 365: Folder sorting resets automatically to AâZ
Outlook 365 â Folder sorting resets automatically Environment: - Outlook desktop app (Microsoft 365) - Exchange / Office 365 mailbox - Dark mode enabled - Multiple shared mailboxes Problem description: Outlook automatically changes the folder sorting/display settings without user action. The option âSort subfolders A to Zâ reactivates randomly during the day. The configured sorting (e.g., Received â Descending) resets several times per day. In View Settings, the sorting remains configured correctly, but visually Outlook displays a different order. The issue occurs across multiple folders (Inbox, shared mailboxes). Actions already taken: - Verified and modified sorting via View > View Settings > Sort. - Applied the same view to multiple folders. - Confirmed that the settings remain saved correctly. - Issue persists: the parameter stays the same, but Outlook displays mails differently after refresh. Possible causes considered: 1. Outlook bug â display refresh resets the sorting visually even though settings remain unchanged. 2. Corrupted Outlook views â local view definition might be corrupted (outlook.exe /cleanviews). 3. Outlook add-in â third-party add-in may override sorting. 4. Exchange synchronization â server-side policy may enforce default sorting on shared mailboxes. 5. Recent Microsoft 365 updates â some users have reported similar issues in 2025 (views automatically resetting). Request: - Confirm whether this is a known Outlook 365 bug related to automatic resetting of folder views/sorting. - Provide solution or patch/workaround. - Official Microsoft recommendations to prevent Outlook from reverting to A â Z sorting automatically.
SPF, DKIM and DMARC bypassed for guest users
I manage a small non-profit using Microsoft 365 Business Basic. Most of the people on our board of directors are added as unlicensed guest users so that they can participate in Teams chats and meetings and to access our Sharepoint without using up a license. The problem: any email sent from an internal licensed user (or shared mailbox) to one of these guest users completely bypasses our domain's SPF, DKIM and DMARC configuration, resulting in bounced emails (particularly for recipients using gmail). Mail sent from an internal licensed user to any external address NOT registered as a guest user correctly passes SPF, DKIM and DMARC checks. I gather that this is because guest users are viewed as "internal" despite having external email addresses, but it seems like a serious limitation if I cannot reliably send email to anyone who is a guest user. Is there any extra configuration I can do to enable SPF, DKIM and DMARC for email to guest users?
Outlook âMessages in This Conversationâ Shows Unrelated Emails Despite Exact Match
Hi, Iâm having an issue with Outlookâs âMessages in this Conversationâ search. When I rightâclick an email, say the subject is âWeekly Project Updateâ, and choose Find Related - Messages in this Conversation, I expect to see only emails with that same subject. Iâve even set the advanced search condition to Subject is (exactly). Despite that, I still get a mix of unrelated emails like âRe: Lunch Plansâ or âQuick Questionâ appearing in the results. It feels like the search isnât respecting the exact-match setting and is just grabbing anything loosely related. its Outlook 2016 Couldnt find any information about it online, any help would be appreciated, thanks.
