If I want to add a new communication, it requires always an email adress (from / to) fields, even when its a phonecall note or anything else but an email.
Providing a new entry without those mailadresses will cause a crash on save (stacktrace shown in window)
Do i miss something?
Can those fields be changed from mandatory?
A communication is usually tagged to a Contact or Lead, hence the mandatory email field. You could remove the mandatory though, it should not be problem.
how is any other note like sales person visit, meeting, phone call, internal actions lieke research stored for a lead or customer?
Same for support:
How can I start a ticket because e.g. a phone call, or snail mail, or a monitoring system?
All field that could be used is named “Raised By (Email)”
