I suspect that X1 will see this is punctuation. The help file says:
In searches, X1 uses "/" to denote "near". So you are probably screwed if you want to search for that.
Where are these folders? Windows does not like that in a folder name. So I suspect that you are talking about Outlook folders.
In the past I have found that using characters that Windows dislikes causes grief with addons that I use with Outlook. In my case it was the | character.
This doesn't answer your question, I fear.
What are you trying to do with these folders? Find stuff? If so, it probably doesn't matter which mail client you are using. X1 isn't going to work differently.
Can you find folders with that name using Outlook's own search? If the worst comes to the worst, then that would let you find folders and rename them in a more X1, and Zimbra, friendly way.
