Outlook 2010 Public Folder creates many conflicts

Not open for further replies.


I do a lot of Outlook applications development and noticed a problem or BUG with Outlook 2010 and Public Folders.

This is a problem that I can only reproduce in Outlook 2010 Public Folders. I have not seen it occur in Outlook 2007, 2003 nor 2000.

Any time a MAIL item is opened, edited and saved, a conflict is generated.

If the sequence is that Mail is opened, closed, then open, edited and saved, no conflict occurs.

This is a simple problem to reproduce.

1) Create a public folder for a group of users

2) Move some mail into the folder

3) Then on another users computer and Outlook 2010 session, open then email

4) Edit the subject

5) Close the email and save.

6) A conflict shows up.

The thing I observed is that the 1st time a Mail item is opened then closed the Modified Date Time changes. The 2<sup>nd</sup> time the Mail item is opened then closed, the modified date Time does NOT change.

To observe this&hellip;

1) add the Modified datetime to your view and sort descending by Modified Datetime

2) open an unread mail for the 1<sup>st</sup> time. Choose something near the bottom of the list.

3) Close the item. No Save dialog should appear.

4) You"ll notice the item move to the top of the list.

5) Wait 1 full minute.

6) Open the same email and close it. You will notice the time does not change.

The conflict reports that the same users has updated the same item, and that there are multiple edits.

Anyone have a work around for this problem?

Hi, jawe3d

The performance issue may be related to many factors, such as the network or some settings.

I would like to confirm if this issue occurs with all the Outlook 2010 users in your network. Please also let us know where your public folder is located.

First, please highlight a public folder in Outlook and then check connection status. Check if there are any problems from the status.

Second, as this issue does not occur in Outlook 2007, we can also try to start Outlook 2010 in safe mode to see if the problem is caused by some third party add-ins" conflicts.

Start the Outlook program in safe mode

1. Click Start, point to All Programs, and then point to Microsoft Office.

2. Press and hold the CTRL key, and then click the Office program you want to start.

If the problem does not occur in the safe mode, this issue might be related to some third-party add-ins in the Office program,

we can try to disable them. Normally, you could do the following to disable the conflict add-ins in your Office program:

Disable add-ins
a) Click File menu, click Options > Add-in, click Go button in the Manage: Com-in Add.
b) Check if there are any add-ins, clear the checkbox to disable them.
c) Close the Office program and restart it.
d) Add one check back each time to the list of Add-In, restart the Office program, and repeat the above procedure.

Once the issue reappears again, we can determine which add-in causes this problem and then disable it.

Finally you can delete your public folder then recreate it .
