Pfx format
« on: May 05, 2016, 03:31:00 PM »
Dear Comodo Community,

I've registered up for Free Email Certificate, but when I collected it, only received a CRT file, however, in Outlook 2016, ask me for a certificate in PFX format, is there a way to get a PFX file from my CRT file?

Thank you.

I had the same issue and traced the problem to the browser.

At first I applied for the free cert using Chrome and collected it (after receiving  the email from Comodo) using Chrome.  This placed a user.crt file in my Downloads folder (the default for Chrome, I presume).  All seemed fine as I've double-clicked on the user.crt file, selected "Install...", and completed with "Finish".

Checking the certificate store (using "crtmgr.msc" at the "Run..." prompt) also made it *appear* that I had done everything  correctly.  After a lot more Googling, hacking, and rebooting, I'll decided to start over.  This time using Internet Explorer 11 as the browser.  I had to revoke my previous certificate before proceeding.

After that everything went fine and Outlook 2016 recognized the cert immediately (File->Options->Trust Center->Email Security->Choose...).

Other notes: Don't waste your time with Firefox or Edge.  Go straight to IE 11.

My configuration: Windows 10 with Outlook 2016 (from Office 365).
