Exchange 2010 OWA Error Hi All, I'm having an issue with My Outlook Web App for my Exchange Server 2010. When the user visits OWA, they can log in, read emails, reply to emails, view calendars etc but when they try to look at the GAL (Global Address List) or click on the "To" button in a new email, they get the following error: "An unexpected error occurred and your request couldn't be handled."
When you ask to see more details of the error message, you get the following: "Request
User host address: ???.???.???.???
User: My Name
EX Address: /o=Domain/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=MyName305
SMTP Address: firstname.lastname@example.org
OWA version: 188.8.131.52
Mailbox server: EXCHANGE.mydomain.sch.uk
Exception type: System.NullReferenceException

Just an update to this:
I tried logging in using the "Light' version of OWA (designed for low bandwidth users), attempting to open the Address Book and this works fine, so it's only using the standard version of OWA.
Not sure if this makes any difference to the solution to this issue.
If someone could help that would be great.

I'm still having this issue and was curious if anyone had any ideas.

Is this when accessing webmail internal or externally? What SP and RU version are you on? Does your OAB work ok when running Outlook 2010 in NON cached mode?

OWA addressbook error
Looks like your error - solution is ADSIEdit of msExchResourceAddressList - which you can always put back if necessary.

I spent 1 hour and this website until EVERYTHING ticked Green.
I fixed like a boat load of errors.
If it still doesn't work after that, i do have some other tricks up my sleeve. Let me know after you have made sure everything is setup right.
Also FYI, School Agreement applicable. Goto 2012 ASAP, from a "external / internal" standpoint i think personally it's far better. Also, Since Office 365 is soon to be covered by said agreement (for the level up from free to education), I am giving serious thoughts to implementing a hybrid "On Site / Cloud" infer-structure for this.
Anyways ... thats a little derail of you topic. Appologies! Let me know if you fixed after you run through this trouble shooter. If it's still broken I know some places to look.
