We are also experiencing the exact same problem. We are on Office 365 and maintain a multi-user MS Access database. We have a separate Front End which resides on each users PC and the Back End database (MS access database) sits on our server. The database has worked seamlessly for the better part of 10 years. Since around end of November we now regualrly (several times a day) get lock out. Typical pop-ups include:
1. Could not save currently locked by another user
2. Record locked out by other users
3. Wait period for an event timed out.
4. Software just stalls
The current "fix" is to get everyone to exit the database and then rejoin. Not practical. Nothing has been changed regarding the system, access rights, shares etc or the database itself.
Hopefully looking forward to a resolution!
Thanks
John
