Office 2010 "The operation failed. The messaging interfaces have returned an unknown error. If the problem persists, restart Outlook. Cannot resolve recipient."


Hi All,

I see others are having this problem too, I have Office 2010 and when I try to send an email to a group I get the following message

"The operation failed. The messaging interfaces have returned an unknown error. If the problem persists, restart Outlook. Cannot resolve recipient."

I have set up the group again from scratch, and run scanpst, I also changed the SMTP encryption settings from none to auto as was suggested by someone else which made no difference. I am reluctant to set up another profile as I do not know if that will cure it plus I will have to enter the details of my 9 email addresses all over again which would be time consuming!

Any Ideas, please help,

thanks in advance

I am using Outlook 2007.
I of course received an email. I am finished reading it and want to delete
it.
I have tried to delete it and I get this error: "The messaging interface
has returned an unknown error. If problem persists, restart Outlook." And
of course, I am unable to delete the email. I have tried to fix this by,
running the office detect and repair tool, I have run the fixmapi.exe tool, I
have un-installed and re-installed office and I still get the same error when
I try and delete that one email. I can delete everything else, but that one
email.
Help!

Hi,

I have had a problem with Outlook for the last few days. If I try to
reply, forward or start a new message an error pops up saying "The
messaging interface has returned an unknown error. If the problem
persists, please restart Outlook". I have obviously restarted Outlook
many times and restarted the computer repeatedly too.

I've run Windows Update and found nothing new that needs to be
downloaded and the rest of my computer appears to be working fine.

I'm running Microsoft Office Outlook 2007 on Windows Vista Home
Premium.

Any help would be very greatly appreciated!

Thanks,

Tom

I have just opened up a hotmail account and have downloaded 'Oulook
Connector' from the Microsoft website which enables synchronisation of my
hotmail mail to Outlook, however although the installation seemed fine I am
unable to create a new mail, send/receive or even view my email accounts.
These are the error messages I am getting:
New Mail:
The messaging interface has returned an unknown error. If the problem
persists, restart Outlook

Viewing Email Accounts:
Email Accounts - The operation failed due to a registry or installation
problem.Restart Outlook and try again. If the problem persists, please
reinstall

I have uninstalled the Outlook Connector and have re-installed the Outlook
programme onto my computer with no effect ?

Help Please !!

I'm running Outlook 02 on Win XP Pro SP2.

I think this may have been caused by the DST time zone update utility, but
I'm not certain. Here's the situation.

If I try to open a calendar item I get the following error:
"Can't open this item. The messaging interface has returned an unknown
error. If the problem persists, restart Outlook."

If I try to create a new message or appointment from the quick start
toolbar, or clicking a mailto: link on a web page:
"The operation failed."

If I click the "to" "cc" or "bcc" button while writing an email message:
"The messaging interface has returned an unkown error. If the problem
persists, restart Outlook."

Restarting Outlook hasn't helped, nor has running detect and repair.

I opened Outlook in safe mode, and was able to open calendar items. Clicking
a mailto: link on a web page brought up an error about not being able to open
Word as my email editor, but then a standard message window opened, and I was
able to bring up contacts by clicking the to and cc buttons. So everything
seems to be ok in safe mode.

I don't know for sure that it was the time zone update that caused this, but
the errors started coming up around the time I ran it. But there doesn't seem
to be a way to undo that.

Any suggestions? Should I uninstall Outlook and reinstall it?

Hi!
I’ve encountered this error message: "The messaging interface has returned
an unknown error. If the problem persists, restart Outlook", when trying to
open Shared Calendars. Different users and not the same Shared Calendars.
I have installed Office 2007 Service Pack 1 and it doesn’t help.
I have tried to reinstall office 2007, but it doesn’t work.

We have Vista 32 bits. and an Exchange 2003 Server with SP2.
We have the same problems on both Stationary and Laptop computers.
Can someone please help me with this problem. I have searched everywhere on
the Internet without any luck.

On my home PC, I’m using Windows Vista Home Premium as my O.S. and Microsoft
Office Enterprise 2007, and both are completed updated.

When I load Outlook, the main PST file is loaded, of course, but,
additionally, I have a storage PST file (i.e. Outlook Data File) where I
store all my e-mails so that my Inbox and Sent folders don’t become too
large, and also so that my main PST file does not become to large.

The problem I’m having with Outlook is that when I “close” the storage PST
file, I get the following error message “The messaging interface has returned
an unknown error. If the problem persists, please restart Outlook.” If I
restart Outlook, it will automatically load the storage PST file. If I
remove the storage PST file from the hard drive folder where it is stored,
and then restart Outlook, it will ask for the storage PST file. I
“compacted” both files, and have also used the Inbox Repair Tool on both
files, but it doesn’t help.

To make matters worse, I have other PST files I would also like to load into
Outlook, but it won’t allow me to. Further, Outlook will not allow me to
create any new PST files (i.e. Outlook Data Files).

On my office PC, I have 12 to 13 PST files loaded at one time (with no
problems), so it’s not unusual to have several open at one time.

I’ve been having this problem for several months, and I’m beginning to think
that the only solution is to completely uninstall Outlook, and perhaps the
entire Office suite, and then reinstall it.
