same problem as this thread: http://social.technet.microsoft.com/Forums/en-US/sharepointgeneral/thread/f697e60a-7d12-423e-a46b-3639b7d56423 But we don't have citrix We are running MOSS 2007 with maybe 200 users and at least once a week we loose work from Excel 2007 spreadsheets, error "Document could not be saved" attempting to save elsewhere usually results in excel crashing. Any ideas on this? Cheers

I have upgraded one of the machines to office 2007 service pack 2. It seems much better, only one crash during day instead of the usual 10....

Hi, 1. Make sure there is no other person checking out this document. 2. Try to check out this file and edit again. 3. Make sure the users have edit permission for the documents. (Note: if you use the windows authentication, please note that the user account the SharePoint use to open the documents is the user you use to logon your pc.) 4. Go to your library > settings > list settings > version settings to check Require check out section. And you’d better click the learning about Require check out at this section for more information. Hope it is helpful!Seven

Thanks, I'll have a look at that.
