Hello,

Recently, our new  user can't get on OWA because their regional setting page is returning "An unexpected error occurred and your request couldn't be handled."

I've search many site and i've not been able to find a working solution.

I've check the redirection, everything seems ok

Hi,

I have seen this same error before. That issue resolved by Exchange 2010 SP3 RU7.

So please refer to KB 2961522 and install Update Rollup 7 for Exchange 2010 SP3 to solve this issue.

Best Regards.

Ohh, i'll try that this weekend. I had a schedule planned this month anyway.

I'll write back after the update.

Thanks

I installed SP3 CU8 and it has indeed fix the problem,

Thanks
