--- Comment #20 from shashidhar <kshashi1...@gmail.com> --- Hi, We have implemented excel export and triggering emails with excel file as an attachement 4 years back by using POI3 libs. After we switch from POI 3 to POI 5 we have start noticing issue with attached excel file borken due to the file renamed to .xlsx.txt. Also we noticed this issue is not happening when we use the GMAIL email server. Only happening through Microsoft email exchange server. If we 100% sure this issue happened due to the lib's upgrade. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
