Hi all,

We're using a shared mailbox for our support team. Each of us has a specific
color (category) and we mark all incoming mail with our color to have a
quick view of which mail are handled or not.

In some cases (randomly, mostly when we are at the office, rarely during the
night when nobody works) we get the "Could not open item. Try again" error
message when we click on the category box next to the message in the message
list.

In this case, when we open the mail and add the catetgory then escape, it
works just fine...

So we can add the category, but sometimes we have to open the mail instead
of doing it straight from the message list.

Any ideas?

Thanks,

We have a similar approach here, and get this message all of the time. I
have searched and see no type of solution yet from Microsoft. The "old"
technotes out there referencing Office 2003 or 2000 are ineffective on this
issue.

Strange thing here is that one of our support guys does not see this error
at all, so perhaps this has to do with an Outlook setting that may be
affected by the user's PC settings.

This only happens to me when using the shared mailbox. When using my own
Inbox, i can right mouse click and Categorize just fine....

How close is it Microsoft to fixing this issue. This problem only exists in
shared inboxes. My staff has ownership of the shared inbox, but gets the
same error when right clicking the the category.

I do not work for Microsoft, so i am not sure if they are even aware of it
being a problem in Outlook 2007. Have you called TEch Support on this? I
have not yet done that, as I was hoping a solution would be readily available
online. THat does not seem to be the case...

We are also having the same issue in the same scenario. If anyone has
any suggestions or work around (apart from opening the email and then
assigning the category) it would be appreciated if you could post to
this thread.

I have a work-around and a possible cause, but not a fix. The problem
started for me three weeks ago when I installed SP2 for Exchange 2003
server (I had Exchange 2003 SP1 before). Not only have several of my
users been having the problem in this discussion thread, but a few of
my users are also having problems with their Outlook 2007 rules
working. These problems only seem to be occuring on my Outlook 2007
users, not on my Outlook 2003 users.

The work-around is to uncheck "Use cached Exchange mode". Then both
the Categorize and mail rules work.

I tried deleting the .ost file and having Outlook rebuild it. I also
tried docked and undocked modes on my laptops. I even created a brand-
new AD account and mailbox, and logged this user onto a brand new PC
that I put Office 2007 on (not an upgrade for Office 2003 like my
other users having the problem). Still this user got the error when
doing a categorize. If you check 'Use cached Exchange mode" the
categorize and mail rules work for a few minutes but then stop
working, or work intermittently.

Perhaps with this clue, one of you can help figure out the cause.
