We are glad to help, it’s just we need clarify that, the investigation is your charge except system accessed by only us such as GOOD, blackberry, unless your branch delegates first user helpdesk to Apac Service Centre. You may talk to manager to consider it if you would like.
Of course, you can ask us for experience or knowledge data base for case.
Anyway, this case, it’s not known issue or something, still need to go for troubleshooting to identify cause.
Simulate your side, you get this same file,(he still can save in XP, right) and upload where you can access, to see whether you have same issue. It you get issue, you can do any kind of test. It’s time of matter you can identify exact factor of issue. Guess you can simulate it as this time his XP can do so, so not depending on profile/site setting.
User can access from explorer, to check whether user can access file and edit directly.
E.g \sharepoint.fm.rbsgrp.net eamsdeus
In first glance, the file type is xlsm, could it be problem?
Please kindly let us know should you have any inquiry.
Regards,
David
