After deep investigation we identified the CalendarProfile document as source of problem (compiled formula for assignment between color's and senders).

Try:

1) Open Mail Preferences

2) Remove all "colors" assignments (both for messages and calendar entries)

3) Save Preferences

The reason I ask is that some people see color coding as making them more productive.

Hi Miroslav Uhlar

Yes, I had even recreated user's calendar profile. Concern is even if i try to make any changes in any of the Mail preferences or the Calendar preferences and try to save I receive the Invalid Type error. Unable to make any changes.

Hi all - 

Changing sender colors worked for the user recently but then started having this error. I have done the following and none have worked: deleted and created new calendar profile, replaced design (was 8.5.3 and now 9.0.1 using 9.0.1FP7 client...same as my setup), ran fixup, compact, updall, and tried resetting all colors back to default again.

I did notice that I can update sender colors with my ID but when I switch to his, I then receive Notes Error: Error - Invalid Value Type. He has Editor access like all of our users. So that said, I felt there must be some weird ACL corruption. I then tried to remove him from ACL and add back again but nogo. I'm stumped and the only thing I can think of now is to give him a brand new mail file.

Any suggestions are appreciated. Thanks.

Check with notespeek .   I think he has a private caledar profile.  You might want to delete that profile.  Here is a snipper of code you can put in a button

Dim session As New NotesSession
Dim db As NotesDatabase
Dim doc As NotesDocument
Set db = session.CurrentDatabase
Set doc = db.GetProfileDocument("CalendarProfile" ",Session.username)
Call doc.remove (0)

Thank you Barry for your quick reply. I did double check and he did not have a private calendar profile. What I ended up doing was creating a new copy without ACL but included all design and docs. I added ACL entries back, tested with user ID and it worked! Hallelujah!
