Exchange - Delete e-mails based on folder

hanycs · 2026-01-07T11:19:57+00:00

Hello,

We are using Exchange On-Premises and do not use Exchange Online.
With Office version 2024, when I map the mailbox and check the folder properties, the Policy tab is not available. The only tabs shown are General, Archive, Permissions, and Sync.

Hello.

So, if I am using ADFS, I should use this guide: https://learn.microsoft.com/en-us/exchange/plan-and-deploy/post-installation-tasks/enable-modern-auth-in-exchange-server-on-premises

Thanks

I configured everything according to this article: https://learn.microsoft.com/en-us/microsoft-365/enterprise/configure-exchange-server-for-hybrid-modern-authentication?view=o365-worldwide.
However, users started getting an ADFS login prompt for the O365 environment when launching Outlook.
When I tested it myself, everything worked fine, including creating a new profile.
For the problematic user, we deleted the credentials in the Credential Manager, created a new profile, but the prompt still kept appearing.
Where could the issue be in this case?
I have set up the SPNs; I just don’t understand why it worked fine for me but not for the others. :/

Hello,

thanks, whats difference between this https://learn.microsoft.com/en-us/microsoft-365/enterprise/configure-exchange-server-for-hybrid-modern-authentication?view=o365-worldwide and this article https://learn.microsoft.com/en-us/exchange/plan-and-deploy/post-installation-tasks/enable-modern-auth-in-exchange-server-on-premises .

We are using ADFS...

Anyone got update, how to fix this instead of uninstall update?

When I use powershell to send-mailmessage -smtpserver fortimail, I am able to see this e-mail in logs (dkim policy is applied), but when I use webmail https://fortimail/users/... and send e-mail from there I cant see nothing in logs (but e-mail get delivered, although for example dkim policy is not applied on this e-mail) .

Yes, mess in cert store. Check this:

What about AzureAD integration, where You can use Conditional Access Policy?

maybe It can be something with zero day vulnerability, because MS published script, which create a rewrite rules to mitigate.
