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.

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

I installed .NET 3.5 SP1 update and when the server restarted OWA no longer
works and neither to our windows mobile cell phones. I have uninstalled the
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

The page you are trying to access is secured with Secure Sockets Layer (SSL).

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

Thanks in advance !!!





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

Watson report about to be sent for process id: 6600, with parameters: E12IIS, c-RTL-AMD64, 14.00.0694.000, OWA, M.Exchange.Net, M.E.S.R.P.ProtectorsManager.LoadProtectors, M.E.S.R.Protectors.AttachmentProtectionException, 8b03, 14.00.0694.000.

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!

Regards

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
