Exchange 2016 CU10, error signing message.
Versions
- Windows Server Version: Server 2016
- Exchange Version: Exchange 2016 CU10
- Installed DKIM Exchange Version: 3.1.0
Description
Could not sign message:
| 2018-09-06T10:19:09.000 | Could not sign message: Could not load type 'System.Threading.CancellationToken' from assembly 'MimeKit, Version=1.2.0.0, Culture=neutral, PublicKeyToken=bede1c8a46c66814'. |
|---|
Steps to Reproduce
- Install Exchange DKIM signer from release 3.1.0
- Send a message
Expected behavior: To have the emails signed without error
Actual behavior: Error is thrown, email not signed.
So, it says that 2016/CU10 is supported in the readme, but when installing from the latest release it says that its not supported. Any suggestions here?
So, it looks like I had to install from source. I'm guessing the CU10 support is pre-release then?
I have the same issue. Please share with us the steps which helped you resolve this issue
First, I'd remove the transport agent.
- Go to the installation folder in program files and run Configuration.DkimSigner.exe
- Then click configure
- Select Exchange DKIMSigner and then uninstall (don't change any checkboxes, just highlight the name and click uninstall)
Now, download the project repository as a zip
https://github.com/Pro/dkim-exchange/archive/master.zip
Extract to a folder, and then follow the manual install directions:
https://github.com/Pro/dkim-exchange#manual-install
If this is an upgrade, make sure not to override the settings file (it will ask you during the setup). It would probably be a good idea to backup the entire folder in case something goes wrong, so you could restore your settings and keys if necessary. Overwrite any other files.
That worked for me, and I'm signing again. I hope this helps.
I've already tried manual installation. It gives me the same version mismatch error, in the poweshell!
