C lock file

Was this reply helpful? Yes No. Sorry this didn't help. Thanks for your feedback. This is why in our company we recommend Office users are on Semi Annual Enterprise channel. Let others deal with the bugs; we have a business to run! Sadly, this is impacting Enterprise semi annual according to certain threads.

I notice that yesterday's update included a security patch for Jet which could be the culprit. Would that also explain why it's affecting the Semi Annual Enterprise channel - does that channel get security fixes straight away? Is there any acknowledgement of the problem from Microsoft yet?

Small business with only five users, but one suddenly could not use Access database unless all other users were not using it. Noticed when that user was connected the locking file was 0db and empty.

Search led me to this thread which led me to checking the software versions and confirm issue is the same. Have not reverted the users version yet, but assume it would fix it. Similar issue myself as I attempted to even relocate the back end into another shared location but it acted as if my URL for the location was incorrect or did not exist. Hoping to get a real resolution soon as rolling back the update isn't seeming like viable option for us. Permissions info.

You can use FileStream. Lock and FileStream. UnLock for locking the file. I'm guessing that the code for your unlock and lock buttons does not have access to the FileStream where you have locked the file? Do you want to unlock a file that has been locked elsewhere?
