OWA encountered an unexpected error and was unable to handle your request.


Hi,

 

I have just upgraded to rollup 10, and have found that external OWA gives the following message when you try to respond or create a new email.

"Outlook web access encountered an unexpected error and was unable to handle your request"

I have now uninstalled Rollup 10 and rebooted but still have the same problem, internal OWA works ok...

Firefox works without this problem, this problem occurs on multiple clients, multiple accounts all using Ie 7,8

Hi there,

When I open the address book in OWA, either from clicking "To" button or address book icon I get the following error:

"Outlook web access encountered an unexpected error and was unable to handle your request"

The page then refreshes to the login page.  I haven't had a chance to look at the logs on the server as yet but thought I'd first see if anyone has seen this before.

Thanks.

I am hoping someone can assist me.  When opening only one user's account on OWA, his inbox and emails all show up just fine.  If you click on Calendar you get this:

Outlook Web Access encountered an unexpected error and was unable to handle your request.Click here to continue working.
Then of course there are the details:

I had to remove the user's name and of course the company and server name but you get the idea.  Can anyone shed a little light?  I have read that its a .Net Framework 3.5 issue but even removing that does not repair it. 

Thank you so much in advance for any help.

Hi All,

I was able to get Exchange 2007 up and running but I have one small problem. In OWA, I cannot view message details. When I click on the message details button I get the following error: "Outlook Web Access encountered an unexpected error and was unable to handle your request." I'm running Exchange 2007 behind and ISA 2006 server. Has anyone seen this problem before?

Thanks,
Emnet

Hello,

I have a Microsoft Windows Server 2008 SP2 system running Microsoft Exchange 2007 SP3. Recently we have updated our systems using the latest updates from Microsoft (testing on the development platform went without a hitch) and all of a suddent several issues cropped up. This post will be about one of them as I will post the other issues on the appropriate forums.

A major issue we are having after the updates is that our OWA clients cannot send messages via the enhanced interface (for Internet Explorer, etc.). People get messages like the following whenever basic functions like sending a message, looking up contacts, etc.:

Outlook Web Access encountered an unexpected error and was unable to handle your request.

I have tried the Remove-OwaVirtualDirectory commandlet followed by the New-OwaVirtualDirectory commandlet to no avail, the issue persists.
Upon inspection of IIS I have found that I no longer have certain Exchange related "Handler Mappings" within the "owa" virtual directory of the Default Site. Inspecting the web.config file shows me that I should have handlers and/or listed that relate to the following:

I tried various ways of adding these back to the listing under the listing of "Handler Mappings" for the "OWA" virtual directory to no avail. Only the standard handler mappings for a NET Framework enabled IIS web server show up under the "OWA" virtual directory.

How can I get the "OWA" handler mappings back? Using the Powershell commandlets as mentioned before has not done this for me so I am wondering how this can be done.

Thanks.

****UPDATE*****
it only happens when I have the option Use Outlook Web Access Light checked off.
Unfortunately being on a mac most of the time, I can not remove this check box.

my company has a webmail site.
I used to be able to goto it.
We migrated my mailbox to office 365. I was still able to goto webmail, just through new 365 portal.

I was migrated back to on-premise exchange server 2007 and for some reason I can not login to our webmail site on any of the machines I have previously logged on from.

I have tried all 3 of my machines with 3 different browsers on each and I get the same error after entering my credentials. If I log in with another users account, i get to their mail.

If however I goto a machine that I have never used webmail on, I am able to login as myself.
I have tried erasing all previous internet settings, flushed dns, cookies, passwords. I just don't get it.
Anyone have any ideas?

THank you in advance.

The error pops up after I enter my credentials.

I installed .NET 3.5 SP1 update and when the server restarted OWA no longer

update but it still does not work.

Any ideas? below is the full error message.

Running Exchange Enterprise 2007 on Server 2008 Enterprise box. Exchange has
been running fine for last 9-months & OWA was working fine.

We had an issue yesterday where the server became unresponsive (no display,
lost connectivity) so I reset the box. Came up & said it was installing
3-updates, waited for that to finish Then it rebooted itself & said it had
problems & backed out the updates. It rebooted itself again & was installing
the same updates. After it rebooted itself 3-more times installing the same
3-updates, I could finally login. Everything looked ok. Internal/External
messagess were flowing fine. Later we discovered OWA quite working (internal
& external).

If I open IIS7 manager & try to browse the OWA *.80, I get

Any thoughts? At this point I dont know if its OWA, IIS, or both.

Hi,

I have a windows 2008 server R2 with exchange 2010. Everything was working fine, however, I installed sharepoint 2010 and then uninstalled it once i realised it stopped OWA from working at all. Since then, everything was back to normal....except one thing. When i log into OWA, everything logs in okay, i can only view emails without attachments. When i click on an email that has an attachment, it gives me an error within the message pane on owa saying "An unexpected error occurred and your request couldn't be handled."

When i look in the event logs i have a particular log that may be relevant (see below event log message). I am not sure how to resolve this....anyone have any suggestions? 

Start event log message

Hello, this is a tough one. I have been using Outlook 2003 on a laptop
running XP-Pro with 1GB of memory for awhile and today I received this error
(An unexpected error ocurred) when trying to send email. Outlook Express
works OK. The error pops up whether MS Word is used and my test editor or not.

I tried to repair Outlook by choosing this option from the Office Pro 2003
Installation disk with no success. Any assistance in solving this problem
will be greatly appreciated.

Hi,

I have a windows 2008 server R2 with exchange 2010 SP1 RollUp Update 1. When I log into OWA, everything look like beeing ok. But when I try to open the calendar or write an email, I receive "An unexpected error occurred and your request couldn't be handled."

No problems by using light version of Outlook Web App!

We need to do a migration in 2 days, but that problem needs to be resolved!

Hi All,

 

I have a problem in that when I have a user log in via their OWA and try to create a new message, reply, check address book or change any functionality on OWA the get the error "Outlook Web Access was unable to access the Active Directory resource. This may be because the Active Directory object does not exist or the object has become corrupted, or because you do not have sufficient access rights for the object."

THis does not happen to all users but on others it might just be the Address book that gives this error and then on all FIrefoxSafari clients this occurs as well(although I know their are issues surrounding this anyway on Ex 2007)

 

I have had a browse around the forums and can't find a solution for this, although there are people who have experienced this there isn;t a definiate answer out there. Has anyone had this issue and been able to resolve it?

 

Attemted Fixes: Applied updatesService Packs, recreated OWA virtual directories, enabledisable SSL on virtual directory

 

Platform: W2K8 SP2, Exchange 2007 SP3

 

Kind Regards,
Chris

We use a system called blackboard for all our online classes.. Within blackboard there is an email button that allows you to email your professors from within the program. I do not know much more then that about blackboard since it is an external program hosted offsite.. What I do know is that senders have been getting the following error sent to their inbox after trying to email from within blackboard.

Your message did not reach some or all of the intended recipients.

NOW I did make a change that I think should be unrelated, but who knows because the timing is very similar.. Last week I created a new DNS Zone for Post.edu.. (one didn't exist previously).. Within that I created an A record for "mail" and for "www".. The reason I did this was for OWA.. I wanted to use the same mail.post.edu for students to check their email on and off campus.. after I made that change I found users weren't able to connect to www.post.edu from inside campus so I made the A record pointing to the external address..

Any thoughts? I am not sure if the changes I made are releated, but I would hope not..

Thanks

I'm having trouble Receiving, Moving or Deleting Messages using
Outlook Express 6. I noticed the problem when trying to get my
messages one day. I thought the problem might be that my inbox was
too full, so I tried moving a bunch to another folder. The messages
copied to the new folde but did not leave my inbox. I next tried to
delet a message...same thing (went to deleted items but also remained
in my inbox). Next I clicked on a bold message and received an error
mssage saying "Outlook Express was unable to send the receipt". It
says this for all bold mesages. Anybody experience this? Any advice
on what I should do to get this resolved would be GREATLY
appreciated. Thanks!

I am trying to send a group email using a distribution list that has worked
for the last five years.

When I click to send, it gives me a message: "An unexpected error has
occurred". I am using Outlook version 2003, SP3. The message was edited
using Word, and when the error came up I tried unclicking word (tools,
options, mail format) but it didn't solve the problem. With my email open I
tried double clicking on the distribution list, (which has always opened
before) but now it gives me another error: "The command selected is not valid
for this recipient".

We have been using these lists for at leat five years and they worked up
until the computer tech gave us a business server. We have had so many
problems that he "undid" having email go through the server and we are back
to pop mail through an internet provider. While watching him work I realized
that he didn't know how to fix this and was looking for information (and
blowing away my work that was unrelated such as my custom microsoft word
templates, old emails I need to refer to, etc) I decided to take matters into
my own hands.

Thanks ahead of time for your help. If you can help me. If not, we are in
big trouble over here!

What anti-virus application is installed on the Clients? If email scanning
is enabled, see if disabling it corrects the problem.

Why you don't need your anti-virus to scan your email

Otherwise, see if there might be a "stuck" message (a message that will not
download which blocks the download of all other messages in the queue).

I too have had this problem 2 or 3 times in Outlook. But interestingly I only
get the error if I start a new message and type the name of distribution
group into the To: or CC: field directly without opening the Select Names
applet.

Here's why it occurs in my environment. I sometimes accidentally delete a
group when I'm editing it. SO I have to rebuild the group. But when you are
on the New Message screen and you type in a DL name directly into the To
field, you are actually pulling the previously used DL name from a little
quickie picklist - the list of available names when you type directly into
the To: field is actually a list of shortcuts to the distributions lists.
What happens when you accidentally delete a DL is that the link in that list
no longer links to a valid DL. The DL it was linked to is gone.

FIX:
1. Create a New Message
2. In the To:, CC:, and BCC:, fields, type the name of the offending
distribution list, the one you are using when you get the error.
3. Once the list of DLs is displayed, delete the one that gives you the
problem. You are not actually deleting the list, just the shortcut link to it.
4. Click on the TO, CC or BCC link to bring up the Select Names dialogue.
5. Select the offending DL for the To CC or BCC field and click OK.
6. Send your email
7. next time yo usend email you can type the DL right in on the New Message
page and it will now be linked to the correct DL in the address book.

Hope this helps some people liek me!
