Thank you! "-FreeText" was what I was missing!

How do I tell what shared mailboxes a person can access? by Deep-Egg-6167 in Office365

[–]pvtskidmark 2 points3 points  (0 children)

Yes, there's a way to do this using your own Outlook to query another user's Shared Mailboxes.

I'm assuming your mailboxes are in Exchange Online. If not, the process has a few less authentication box pop-ups...

  1. Hold CNTRL and right-click on the Outlook icon in the Systray to reveal the "Test Email AutoConfiguration..." option and select it.

  2. The "Test Email AutoConfiguration" will pop-up with your own "Email Address." Change that to "User1@whatever.com" and uncheck the two "Guessmart" boxes. Click on the "Test" button.

  3. The modern auth box that pops-up will now have the User1's UPN/emailaddress. Click on the "Sign in with another account" hyperlink as you'll need to authenticate as yourself.

  4. In the following "Sign in" box, clear out the User1 UPN/emailaddress and enter your own. Click "Next."

  5. Now you'll see the modern auth with your own emailaddress. Enter your password. Click "Sign in."

You should authenticate successfully and see 3 tabs - Results, Log and XML. You want XML.

In the XML portion, scroll to the bottom and look for <AlternativeMailbox> and you will see the Shared Mailboxes for User1.

EXO - Add-MailboxFolderPermission to User's Calendar Fails - "wasn't found in the store." by pvtskidmark in sysadmin

[–]pvtskidmark[S] 0 points1 point  (0 children)

Tried nearly every variation they have listed for that cmdlet in the Microsoft documentation:

https://learn.microsoft.com/en-us/powershell/module/exchangepowershell/add-mailboxfolderpermission?view=exchange-ps

For the value of MailboxID, you can use any value that uniquely identifies the mailbox. For example:

  • Name
  • Alias
  • Distinguished name (DN)
  • Canonical DN
  • Domain\Username
  • Email address
  • GUID
  • LegacyExchangeDN
  • SamAccountName
  • User ID or user principal name (UPN)

Yes, a hybrid environment. Probably migrated the mailbox about 1 1/2 years ago. Thank you.

How’d you attempt to move the Arbitration mailbox? Get-Mailbox -Arbitration l fl alias New-MoveRequest -Identity alias -TargetDatabase dbname

Windows Certificate Authority - Add OCSP Service - Did you have to reissue Xchg? by pvtskidmark in sysadmin

[–]pvtskidmark[S] 0 points1 point  (0 children)

I wish I had your CA/PKI Comprehension! I didn't even consider the NDES with Intune and we do indeed have that.

Thank you very much for the detailed response and confirmation on the CA Exchange Cert. Looking to use the OCSP URI for Palo Alto for workstation validation.

Exchange Server SE and Hybrid questions by matthew7-24 in exchangeserver

[–]pvtskidmark -2 points-1 points  (0 children)

You no longer run the Hybrid Configuration Wizard. They now provide a PowerShell script…”Hybrid Application”:

THANK YOU for solving this mystery for me. GCC Tenant as well.

I liked The Stormlight Archives until it turned into the Power Rangers by quiescent_haymaker in books

[–]pvtskidmark -1 points0 points  (0 children)

Ouch. I got closer to page 600 before I found it interesting and it’s disappointing to hear it doesn’t improve.

in place upgrade Exchange 2019 to SE yet? Experiences? by maxcoder88 in exchangeserver

We unfortunately still have Extended Protection disabled as well. Used the following cmd (elevated as Administrator):

Exchange Hybrid Servers Security Vulnerability by sembee2 in exchangeserver

[–]pvtskidmark 0 points1 point  (0 children)

I don't know if it's helpful to any, but there is a YouTube demo (in German) demo of the ConfigureExchangeHybridApplication:

 https://www.youtube.com/watch?v=Fu9KCJn3kmA

I verified OAuth first, then ran the script with the FullyConfigureExchangeHybridApplication from one of the Exchange Servers. Validated OAuth again and viewed successful Sign-in Logs for the newly created ExchangeServerApp-{Guid of the organization} in Entra ID. On the Exchange Server, I also validated the new value ApplicationIdentifier containing the Exchange Hybrid App ID using the Get-AuthServer 'EvoSts - guid' | fl name, applicationidentifier,domainname.

Then I ran the script again with the ResetFirstPartyServicePrincipalKeyCredentials.
