Outlook 2007 shared calendar messaging interface error

[Trumpeter]

I am running Outlook 2007 in an exchange 2003 environment. For 2 of the
shared calendars I access, most times I try to display them, I get an error
that says "The messaging interface has returned an unknown error. If the
problem persists, restart outlook." It doesn't fail 100% of the time, but it
does usually fail. I have access to 5 other calendars that work fine. I
double-checked the permissions on the 2 that work, and I have author-level
permissions. The affected calendars display properly for other users in the
office who are running outlook 2003.

I've seen the error on the knowledge base with regards to printing a shared
calendar, but not for simply displaying them, as I am trying to do. Anybody
have any insights?

[Trumpeter]

Anybody have any thoughts?

I have a same proble Trumpeter has. I have Outlook 2007 in an exchange 2003,
too. Generally, outlook works well, but sometimes that message just pops up
and bother me. After restart, it works ok which make me crazy again. I
checked the permissions as Trumpeter did, but it didn't help me.
Do you guys think it is kind of bugs of new software or just Trumpeter and I
have a unique problem?
If you guys know about this bad situation, please let me know

My company is having this same issue. We recently upgraded all users
from Office 2003 to 2007.

This first started with just two computers but little by little more
users are experiencing the problem.

When someone clicks on a shared calendar they get an error saying "The
Messaging interface returned an unknow error, if the problem persists
restart outlook"
After restarting outlook it goes away but only for a little while.

We have tried to repair and also reinstall office 2007 on the machine
to no avail. All permissions are OK. Not sure if this is an exchange
problem or an outlook issue.

Just wanted to join the chorus, am experiencing the exact same
problem. Outlook 2007 vs. Exchange 2003 - shared calendars randomly
give me an:

"The Messaging interface returned an unknow error, if the problem
persists
restart outlook"

Have anyone found a solution?

I am having the same problem. It is random as to whose calendar I will
receive this same error when I click on it. I have people using Outlook 2003
and 2007 and this error is not prejudiced. Close/re-open of Outlook does not
resolve. If I close Outlook and go into Task Manager, I see Outlook.exe
running and I select End Task. Upon re-opening Outlook it then works
appropriately.

I have also posted another thread specific to shared calendars not always
saving upon close/re-open of Outlook. Sometimes they are all there,
sometimes they are not, and sometimes just some of them show. I'll bet this
has something to do with this as well.

[SunKing]

I have reproduced this problem (where all shared calendars exhibit this
behavior) by having Outlook open and then hibernating my laptop and then
opening it back up. It seems that a temporary drop in communication with
Outlook Client vs. Exchange Server results in a loss of connection and thus
results in this error. As mentioned before, I have to completely kill
Outlook and re-open it to re-establish the connection and resolve.

Along these same lines, I would think that perhaps other kinds of
"disconnections" between the Outlook Client and the Exchange Server may very
well result in the varied behavior where clicking on some users provides this
erorr and others don't (perhaps if the affacted user of the shared calendar
loses his/her connection?).

It seems to me that this is a bug, whereby if the Outlook Client loses its
connection with the Exchange Server, upon reconnecting it should re-establish
the connection with the shared calendars (as opposed to returning an error
and forcing a complete shut-down/restart of the Outlook Client).

I would be curious to hear others thoughts on this as well and if they can
also see that disconnections cause this error.

Hello,

Got the same problem with Outlook 2007 on winXPsp2 PCs. After
reading Sunking post, I have set the hibernate parameter to 2 hours
and POUF! the problem goes away.

Microsoft should read this post and release a hotfix.

[Milly Staples [MVP - Outlook]]

Yeah, the scads of information you have in your post is a roadmap for a hotfix... sigh

After furious head scratching, Lenglo asked:

[SunKing]

Hi Lenglo - Can you please elaborate on the location of the hibernate
parameter for me? I am unfamiliar with that config, but I certainly would
like to try this out myself.

Thread Note: This continues to happen even without hibernating in a random
fashion for me (sometimes certain shared calendars do this and others don't),
but for sure every time I hibernate it does.

Thanks in advance! -SunKing

Look under screensaver properties. As you wrote, it continues to
happen to on of our users too but in very rare circomstances.

[SunKing]

Thanks. I think we are talking about 2 different things, though. When I was
speaking of "hibernating" I was meaning Start\Shut Down\"What do you want the
computer to do?" and select "Hibernate" and "OK".

From your latest response, I think you are saying that the screen saver
activates; or possibly you have a way to actually hibernate your machine
through that interface? I could imagine that would be possible - I just don't
have that option as far as I can see.

Depends on your version of Windows. For Windows XP, look in Control
Panel>Performance and Maintenance>Power Options.

[SunKing]

Thanks, Brian. I see it now.

I think this confirms my suspicions that this appeared to be happening
randomly for Lenglo as his machine was set to hibernate after X amount of
time. The fact is, I have mine set to NOT auto-hibernate at all. When I see
the problem is when I purposely hibernate my PC to un-dock it (i.e. if I am
going to a meeting so I can quickly bring it back up). Shut Down/Restart is
not an option for me as that whole process typically takes 20 minutes :(

[davisr65]

I too have just upgraded from Outlook 2003 to 2007, and all of our
secretaries are complaining of the same issue when accessing shared
calendars....

Thanks...

[SunKing]

Yes, I continue to see this problem too. While hibernating a PC certainly
almost always "breaks" this connection, it continues to happen randomly even
when I do not hibernate the PC.

Try to install this fix

It fix a lot of "unknown" issues for us

[SunKing]

It's not Generally available for download. I guess they are going to roll it
into a future SP. You can contact them and ask for it, but I don't know
where to begin doing that and if I would have to pay for it.

You don't have to pay for that!

Did you get the fix? Let me know if it fix your issue

thanks

[SunKing]

I just got it today. I have installed it. Unfortunately I will just have to
watch it over a period of time to see if it will resolve (as this is somewhat
of a random issue). I will post any updates I have here.

Nope! Sorry to say, it does not resolve the issue. I had an instance today
where I opened my calendar and received the same error. I consulted with my
employee whose calendar now will not open and she says that she did not
disconnect or do anything out of the ordinary. I will say that I know I
viewed her calendar earlier in the day sucessfully. Furthermore, I will note
that I had Hibernated my laptop over the weekend and docked it this AM. At
some point things were moving slowly, so I rebooted it. I do not know if I
viewed her calendar pre or post reboot. Nevertheless, all other calendars
are in full view and are not seeing this issue.

[hl2]

Our company also have Exchange 2003 with Outlook 2007 clients (we've
deployed Office 2007 to about 500 clients). A lot of people experience
this error. E.g. clicking a shared calendar will display "The

messaging interface has returned an unknown error."

Also, "View group schedules" have an error. If you add some persons
(e.g. 40-50) and try displaying their calendars, it will not update
all information on all persons. Sometimes all you can see is the free/
busy information, even though you are allowed to read the content of
their schedule.

It seem to me that Outlook 2007 have a bug when it comes to connecting
to Exchange 2003 servers, and I would have no problem showing this
problem as it happens like every day.

The problem is not related to Laptops and/or power save. I have this
problem at several workstations with no power-savings. Also, the
problem is present at both Vista and XP SP2. We have no problems on
our Outlook 2003 clients.

[SunKing]

I also encountered the issue again yesterday - no laptop hibernation or
anything. In the morning the calendar of the employee showed fine. Later in
the afternoon I could not view it anymore and received the error. This is
still broken.

[hl2]

I've ran Sysinternals Procmon and ran a trace on the error. Here's
some interesting:
OUTLOOK.EXE:
RegOpenKey,"HKLM\SYSTEM\CurrentControlSet\Services\Tcpip
\Linkage","REPARSE","Desired Access: Read"
RegQueryValue, HKLM\System\CurrentControlSet\Services\Tcpip\Linkage
\Bind, "BUFFER OVERFLOW","Length: 144"
"RegQueryValue","HKLM\System\CurrentControlSet\Services\Tcpip\Linkage
\Bind","SUCCESS","Type: REG_MULTI_SZ, Length: 472, Data: \Device

{BFEF283F-5816-41CA-81D2-9F6D047847B5}"
Then it just overflows again when connecting to Tcpip\Linkage\Bind.

The problem is also present in Outlook 2007 SP1.

After running Outlook over 24hours and tried to open a shared
calendar, I get the following error: "Cannot display the folder. The
information store could not be opened."

[Tony Holland]

I called into microsoft and opened a ticket about this problem for my company
here is the response.

Problem - Getting error message while opening shared Calendar.
Environment – Outlook: 2007, Operating system: XP SP2, 100 computers in
organization, 100 computers affected.

So am I to understand that the problem goes away if using Exchange
2007 server (we are currently using 2003 and have the same problem
with some users that view multiple calendars). We are going to update
to Exchange 2007 in the very near future and hope that will clear the
problem.

Thanks all for the good information,
Bill M

[Tony Holland]

Nope we are running Exchange 2007 and stilll have this problem. I thought
the same as you and upgraded to 2007 hoping this problem would go away it has
not. Microsoft supposedly is going to be releasing a hotfix in Feb. to fix
this.

Any update on this as I am also having issues excact to this..

Indeed, this thread has been helpful, though an actual fix from MS
would certainly be nice. If anyone knows of the status of this

There's a non-public hotfix available! I found this link while

http://www.itexperience.net/2008/03/02/the-messaging-interface-has-returned-an-unknown-error-if-the-problem-persists-restart-outlook-in-outlook-2007/

It also fixes some other problems, like the Windows Desktop
notification window popping up, even if you chose not to display it
again.
