Hello Team,
I've been struggling with this all week, and am running up against a deadline to make this work for my team. Here are the essentials:
  • The MS 2021 Access DB sits on a SharePoint Server;
  • The SharePoint permissions have been granted to Everyone;
  • The code updates with a new record perfectly every time from my desktop;
  • When other users attempt to update the DB, the response is an error code 3709, "The connection cannot be used to perform this operation. It is either closed or invalid in this context."
  • I've adLockOptimistic and adLockPessimistic without any yield;
  • I believe that it has to do with MS Access creating the record lock file, laccdb, but I am no MS Access SME, so hear I am...
  • Client Settings: Default Open Mode:=Shared; Default Record Locking:=No Locks.
Thank you, in advance, for your time and assistance.

Excel Facts

How to create a cell-sized chart?
Tiny charts, called Sparklines, were added to Excel 2010. Look for Sparklines on the Insert tab.

What little experience I've had between Access, Excel and SP had to do with automation. AFAIK, SP is basically a web server, and Access never did play well with web based db's. Perhaps this will help, or you can explore the topic to see if you're on the wrong track.

Don't miss the note labeled "important".

You should post more than a few lines of code within code tags (use vba button on posting toolbar) to maintain indentation and readability. I'm too old and cranky to even bother reading code like that.;)

EDIT - also see Daniel's post on the subject. He's been around a long time and knows his stuff.

Thank you, Micron. Daniel's post was great for getting the ACCDB published to the SharePoint server; in that train of thought, I was able to find a MS post that was helpful in bringing the project home.
