Special Characters NOT to Use in IMAP Folder Names

As I discovered when switching from a POP3 account to IMAP for Office 365, importing folder names containing certain characters will abort the process. These are:

~ ` ! @ # $ % ^ & * ( ) _ + = { } | [ ] \ : ” ; ‘ < > , . ? /

Some may get through, but I discovered two I was using certainly didn’t.

I used the tilde character (~) at the start of some folder names to indicate the contents were old and should soon be deleted. I also used the slash (/) within other folder names.

I had to clean up the PST account and re-export it before I could import it into the OST account (seeĀ PST vs OST).
