Hi, From the OWA certificate error, we need first to verify whether a valid certificate has been issued to OWA in Internet Information Services(IIS) manager. 1. Please open Internet Information Services(IIS) manager(Note: Start-Administrative Tools- Internet Information Services(IIS) manager) 2. Find OWA virtual directory under Default Web Site and then right click on it. 3. Please navigate to Directory Security tab, click on View Certificate in Secure communication area. 4. Please check against Issue to on General tab to verify whether it is the same with the site name.(Note: URL for OWA: https://sitename/owa ) 5. Please check whether the certificate has a private key. 6. Please remember the Thumbprint(Note: you can find it from the drop-list in Detail tab) of this certificate, we need to find this certificate from certificate MMC. Then we need to verify this certificate in certificate MMC. 1. Please type MMC from a command prompt. 2. Click File-Add/Remove Snap-in-Add-Certificates-Add-Computer Account-Local computer-Finish. 3. In the console, please check whether it is under Trust Root Certification Authorities 4. Please find the certificate and check whether it is the same as the one for OWA virtual directory. Meanwhile, I would like to know this issue occurred when you use External URL to access OWA or internal URL. Besides, please check whether event source of 5000/1010 is Microsoft Exchange Load Generator, please post the detail event information here. Whether you can run other cmdlt in Exchange Management Powershell. Hope it helps. Xiu

Thank you for your response! No, the certificate does not match- Thsi is a non-split dns sute- name is https://owa.sitename.org/owa Exchange shell does not let me use the get-certificate commands.That's when I get: Event ID: 5000 EventType e12, P1 c-rtl-amd64, P2 08.01.0240.006, P3 powershell, P4 s.xml, P5 s.x.xmltextreaderimpl.throw, P6 s.xml.xmlexception, P7 cea8, P8 02.00.50727.1433, P9 NIL, P10 NIL. How can I add a correct certificate to Exchange? Can I safely remove the others? Thanks!

Hi, Then please remove the certificate that you do not want from the certificate MMC. And then navigate to the IIS manager.From the default web site- Directory Security, please remove the certificate and install the new certificate. Or you can use cmdlt to remove the exchagne certificate from the local certificate store: Remove-ExchangeCertificate -Thumbprint 5113ae0233a72fccb75b1d0198628675333d010e More information share with you: Remove-ExchangeCertificate http://technet.microsoft.com/en-us/library/aa997569(EXCHG.80).aspx Certificate Use in Exchange Server 2007 http://technet.microsoft.com/en-us/library/bb851505(EXCHG.80).aspx How to Configure Outlook Web Access Virtual Directories to Use SSL http://technet.microsoft.com/en-us/library/bb123583(EXCHG.80).aspx Hope it helps.
