Why you couldn't open this hot mail account medcedess.k.chanhotmailcom?

It seems there was an issue with the email address format. The correct format for a Hotmail account should include an "@" symbol before "hotmail.com," so it should be "medcedess.k.chan@hotmail.com." Without this, the email address is invalid and cannot be opened or used. Double-checking the format can help resolve the issue.
