Link in acceptance email for the preview program for Microsoft Defender for Business doesn't work

Copper Contributor



I requested access to the preview program for Microsoft Defender for Business. I received an acceptance email containing the following instructions:

  1. Go to this address using an incognito browser window:
  2. Follow the prompts to activate the trial and complete setup. To activate the trial for an existing tenant, you must be a global administrator in Azure Active Directory. 

When I do this, nothing happens (see Screenshot)

I am also experiencing this problem. Did you manage to find any solution to this Psantus?

@Marc8745 no.

  • asked me to log this here.
  • told me that issue was known on their side, and that they'd come back to me when fixed.
Thank you for replying so quickly, and thank you for letting me know!


If you right-hand click on the link and choose "Copy Hyperlink" and then paste it in to an Incognito Browser, does it work?  After this was suggested on another post, I tried this and had success.  Apparently the Incognito Browser session is important.

Nope it didn't. I did the whole thing with Microsoft support Team and nothing worked.
