0226 | MS Exchange : CryptographicException: Invalid provider type specified

Wednesday, August 2nd, 2017 Posted in Windows Server | 1 Comment »

There’s issue when installing/renewing a certificate to MS Exchange.

System.Security.Cryptography.CryptographicException: Invalid provider type specified

This is the explaination (reference: MS Technet > exchange server 2013 > Unable to access ECP/OWA)

The basic problem is that the Exchange code cannot properly handle X.509 certificates signed with the new and mighty Microsoft Software Key Storage Provider (which is kind of funny)

To fix this, do the following step:

Export the certificate as ‘pfx’ file then remove it from the certificate store.
Open ‘Exchange Management Shell’
Type command certutil -csp "Microsoft RSA SChannel Cryptographic Provider" -importpfx c:\path\to\certificate.pfx note to change ‘c:\path\to\certificate.pfx’ to the path of your certificate exported from step 1.
Type certutil -store my, (see sample output below) Check if the ‘Provider = ‘ line is ‘Microsoft RSA SChannel Cryptographic Provider’. Copy the hash after ‘Cert Hash(sha1):’
Enable the certificate for Exchange. Type Enable-ExchangeCertificate -thumbprint "00 11 22 33 44 55 66 77 88 99 aa bb cc dd ee ff 01 23 45 67" -Services "iis,pop,imap,smtp"
Restart IIS.

ทำแล้วก็จดไว้ครับ

ก่อนอื่นสร้าง powershell script เซฟไว้ซักที่ (สมมติ c:\scripts\email.ps1)

$message=Get-WinEvent -logname "Microsoft-Windows-TerminalServices-LocalSessionManager/Operational" -maxevents 10 | Where-Object {$_.Id -eq 21 -OR $_.Id -eq 25 } |Format-List -Property * | out-string -Width 100
send-mailmessage -to EMAIL@EXAMPLE.COM -Subject "Login Event on " -SmtpServer mail.domain.com -From db1@warz.extreme.co.th -Body $message

เตรียม smtp server ให้เรียบร้อยด้วยนะครับ

แล้วไปที่ task scheduler กด create task หน้าแรกกรอกประมาณนี้
