When I try to close excel or save a file, the following error appears as per attachments. I noticed the error started when iMac updated to version 10.13.1 (High Sierra)
I have also updated Excel software, but error still appears. Please fix.
I also have the same problem when closing or saving a file. Error message appears inviting me to send the same screen shot as above. Appreciate any advice.
