I need to remove an email from multiple exchange online mailboxes
PowerShell & Exchange Online. We had an online crime tips email sent to a distribution group in or organization. It has sensitive information related to an investigative case we're working on. We are a Law Enforcement Agency. I can connect to exchange with PowerShell but haven't been able to remove the message. Anyone have the proper syntax or guidance to share? Thank you!
Intermittent issues with PowerShell Command Responses Since May 10, 2025
Since May 10, 2025, we have observed unexpected behavior intermittently in the responses of the following PowerShell commands. Could you please investigate the issues outlined below? Get-CsTenantFederationConfiguration: The AllowPublicUsers property appears in the command output, but when the response is passed to ConvertTo-Json, the AllowPublicUsers value is missing. Please refer to the attached screenshot for reference. Get-CsExternalAccessPolicy: The EnablePublicCloudAccess property, which is expected to return a boolean value, is now returning null. These issues are not isolated to a specific instance — we are intermittently observing the same behavior across multiple Office 365 tenants. Looking forward to your assistance.Connecting to multiple Microsoft services with the same session
Hi guys. Working on a script that needs to connect to ExchangeOnlineManagement, TeamsOnlineManagement, SharePointOnlineManagement.... The script will be used across many different tenants, and I also plan to make it publicly available, so 1) I don't really want to pre-configure some complicated key setup and 2) I don't really want to have login pop-ups over and over again... For ExchangeOnline, I learned (accidentally), if I do this: $upn = Read-Host -Prompt "input yer wahawha" Connect-ExchangeOnline -userprimaryname $upn Connect-IPPSsession -userprimaryname $upn And login to MY tenant, I don't get prompted for login. I think likely because my device is Entra-joined, and it's using my Microsoft account. But even if I use a different account, it will only prompt me once - reusing it for the other. This is great, and exactly how I wanted things to flow - but now I'm trying to do Connect-SPOService (sharepoint) and Connect-MicrosoftTeams... and while both of these are part of the tenant, they don't take the -userprimaryname param - so I can specify to use the account I'm logged into my PC with.. The end-goal is to have this script run with minimal user input. I've SORT OF found a workaround for SharePoint, where I can get the SharePointSite from ExchangeOnline, then modify it a bit and use it as input for Connect-SPOService... but Teams, while it doesn't have the URL param requirement, DOES prompt me to login again. Is there a way to use the existing session for either of these, like I've done with ExchangeOnline / IPPSSession? We have MFA enabled, though not required from within our company network - but when I try to use Get-Credential, it errors me out because it wants MFA.
Purview -> Powershell
i need to export some users their data before their licenses are removed. It is about 60 users, so i would rather user powershell instead of the purview portal to automate the job. So i have been playing around with the commandlets, to get an idea to build the script. The strange thing is what i see in Powershell is not represented in the Purview portal. We had an older compliance case which was no longer used. I tried to remove the compliance case by the Purview portal, but nothing happens when clicking "delete case" or "close case". i then reverted back to PowerShell by using the Remove-ComplianceCase "$CaseName", where the compliance case was successfully removed. When running the Get-ComplianceCase, i can see that the old compliance case is indeed removed, however the removed compliance case is still present in the Purview portal even several hours after deleting the case with PowerShell. Then started to play around with a new compliance search New-ComplianceSearch -Name "$($TargetMailbox.displayName) License Cleanup" -ExchangeLocation "$($TargetMailbox.PrimarySmtpAddress)" -Case "License Cleanup" -SharePointlocation "$($PNPPersonalSite.url)" after refreshing a couple of times i could see the compliance search in the purview portal. Then started the compliance search by using the Start-ComplianceSeacrh commandlet and verified that the search status was completed: Get-compliancesearch "$($TargetMailbox.displayName) License Cleanup" | select status However in the Purview portal no statistics were shown (not available yet). Didn't spend to much attention as i already saw discrepancies between the purview portal and what i saw in Powershell, so continued exporting compliance search with a compliance search action to export the data in the process manager New-ComplianceSearchAction -SearchName ""$($TargetMailbox.displayName)" -Export Can successfully retrieve the compliancesearch action in Powershell and can see that the status is completed, but fail to retrieve the export in the purview portal. Get-ComplianceSearchAction -case "License CleanUp" -includecredential | fl Did not achieve a way in downloading the export results via PowerShell, but would already be pretty pleased if i could achieve the first two steps via PowerShell. But as i am unable to retrieve the export in the Purview portal, i am afraid that i am still stuck. I can create an export in the Purview portal from the compliance search i created in Powershell. Can anyone please explain me the issue with the discrepancies between what i see in PowerShell and the Purview Portal and is it possible to see the exports created in powershell in the purview portal? And is it feasible to download the export from Powershell as well (Start-Process)?
Change work hours
Hello, I am trying to change users' work hours as I would do via the web interface. However, I am unable to find a way to do this using PowerShell. I’ve seen suggestions to use Set-MailboxCalendarConfiguration, such as: Set-MailboxCalendarConfiguration -Identity email address removed for privacy reasons -WorkingHoursStartTime "09:00:00" -WorkingHoursEndTime "17:00:00" However, I need to set different working hours for each day, and I can’t find any parameters that would allow me to do this. Is this possible? Do I need to use Update-MgUserMailboxSetting for this? Thank you, AlejandroThe term 'New-MailContact' is not recognized
Hi Support, I am trying to bulk import external contacts to the tenant. I have come across several other Q&As which have the similar issue. However, the issue is slightly different - I have assigned this test account recipient management role which should be able to create mail recipient and related stuff. This user, eg, test user, is able to do it from the online version from exchange admin center but cant use the cmd to run via powershell. It was working probably a week ago and I haven't changed anything. It also works fine when authenticating using a global admin account. Looking forward to your reply. Thanks in advance, Sheila

Hello, we have just finished migrating our company from Google Workspace to O365. Things went more or less smoothly, but now we're noticing that all of our migrated calendar events still have the Google Meet link associated with them. Is there a way to bulk remove all Google Meet links from all of our calendar items and replace them with Teams links? Many thanks in advance!
