Parameter name: pUnk

This error only occurs for one user of the database,

When they use Write | Email from template

The email creates,

they click Send and they get an error "the operation failed", they click OK,

an error dialog pops up with "Value cannot be null. Parameter name: pUnk"


I've tried the suggestion here: but that hasn't worked.


Anyone got any suggestions?

Hi Ben,


Does this happen if the User tries from another machine?


Try these and see if they help:

regasm redemption.dll

delete and restore ACT! Prefs via ACTDiag

Detect & Repair Outlook
