Issues opening Excel attachments

Clear Outlook’s Secure Temp folder

Main possible cause that Excel attachments are not opening correctly or with an error is because of other Excel files or templates in Outlook’s Secure Temp folder. 
The Secure Temp folder is the folder that Outlook uses to (temporarily) store attachments to that are being opened directly from within Outlook. Under certain conditions, this Secure Temp folder is not always cleaned correctly. 
In that case, you can clean it manually and see if the attachment is opened correctly now.
