I was wondering what the max. length restrictions are for SharePoint Online Managed Metadata Service: - TermGroup name - TermSet name - Term/Label name/value

I could not find anything on MSDN. A link to a source or reference would be fantastic, too.

I did a quick test and it seems TermGroup, TermSet and the Term have 255 character limit:

I don't think it is documented


A note in the dot net doc's for the Label (value) matches the findings from @SharePointer

The Label can not have more than 255 characters, and cannot contain any invalid characters including: semicolon, double quote, left angle bracket, right angle bracket, ampersand, pipe, and tab.
