MS states that color categories in Outlook 2007/2010 are different than previous Outlook versions and are not stored with the pst files (which we use Exchange, cached, ost files) so MS states you can't migrate them between Outlook mailboxes which confuses me because the other user claims that his categories changed when he got the shared calendar. I continued my search for a solution and didn't find one. There is no additional charge to use our email service powered. I checked the shared calendar properties to make sure both users had the same permissions (which they we identical) and made sure the settings for the calendars we the same (which they were) so, I started to look for a solution (on the web) and used an idea from reading a blog that had me updating the color categories in the mailbox properties. Frontier Yahoo Mail lets you check your email from any device you use to connect to the internet. I checked this out and that user claims that when the shared calendar appear in his Outlook, it had the color categories showing (and claims that his categories list changed to match the shared calendar when he accepted it).
She told me that another person in her department received the same invite two months ago and he has the color categories showing in the shared calendar. She got the calendar however, no color categories appeared. I have a 2010 Outlook client that shared a calendar to an Outlook 2007 user via email invite.
