Exchange 2010 Sp3 Ru7 OWA search is not working

Issue : OWA search is not working for all of the users, No issues with Outlook users on Exchange 2010 SP3 RU7 on SBS server

Troubleshooting steps performed
1. Last time When Index catalog has been built : Recently

2. How many users are facing this issue : All

3. How many nodes of Exchange server : Single

4. What if Mailbox moved to another Server/ Database : Not possible (SBS)

5. Since when Users are facing this issue : After installing Windows Update

6. Is Search is working for outlook Client : Yes

7. On newly Created Test user, Search is working : Not working

9. Test-MailboxDatabase –MailboxDatabase <DB> : Error "Time out for test thread"

10. Test-ExchangeSearch :  The MSExchangeSearch service isn't running.   

11. “Microsoft.Exchange.Search.ExSearch.exe”  from Task Manager and check the processor : Normal , between 6% to 12%

12. Please check Search on Different Internet Browser like Chrome or Firefox : Same issue,Not Working

13. Download SymLink from Repair-ExchangeSearchSymlinks.ps1 and run the command (this script repairs symbolic links) : Still Search is not working

14.  .\ResetSearchIndex.ps1 [-force] <dbname> [<dbname>]...

You will receive an Event ID 109 when the rebuilding of the index starts for each database and an Event ID 110 for each database when the index rebuild has completed : Still Search is not working

15. After receiving Event ID 110 for each database, test to make sure search functions correctly with both OWA and Outlook operating in Online Mode : Still Search is not working

16. From Exchange SP3 media, Goto Setup.Exe folder and from Command Prompt with "Run as administrator" First run setup /PrepareAD and then run setup /PrepareSchema and after that reboot he box and make sure “Microsoft Exchange Search Indexer Service” and “Microsoft Information Store” service is started and checked the issue


Now, issue is resolved

“Your mailbox can't be accessed using the address you entered, please obtain the correct address, please contact your helpdesk”

“Your mailbox can't be accessed using the address you entered, please obtain the correct address, please contact your helpdesk”

Method1:

To proceed to the control panel you can access the EAC by adding the Exchange version to the URL. For example, to access the EAC whose virtual directory is hosted on the Client Access server locally, use the following URL: https://localhost/ecp?ExchClientVer=15.
Same way applies if you want to access the Exchange 2010 ECP and your mailbox hosted on an Exchange 2013 Mailbox server, use the following URL: https://localhost/ecp?ExchClientVer=14

Method2:

Through PowerShell create a new mailbox on Exchange 2013 and give it the necessary administrative permissions.

Troubleshooting Steps : The Proxy address "MBX:0" is already being used by org/users/username

Issue : Error received when for few user tried to change the "Set as Reply" 

The Proxy address "MBX:0" is already being used by "org/users/username". Please choose another proxy address

Resolution :  From the ADSIEdit.msc, remove the Problematic address from the Attribute "ProxyAddress"

Users had been migrated from Exchange 2003 to Exchange 2010, while moving mailbox Exchange stamps mailbox for processing with MBX:0 and MBX:1 likewise

Cross Forest Migration

Tools

1.  Microsoft Identity Lifecycle Manager (ILM) 2007 Feature Pack 1 (FP1) 
2. MIIS
3. FIM, other 3rd party dirsync tool, etc

2. Scripts

(a) This example configures the Availability service to retrieve per-user free/busy information on a Mailbox server in the target forest.

Get-MailboxServer | Add-ADPermission -Accessrights Extendedright -Extendedrights "ms-Exch-
EPI-Token-Serialization" -User "<Remote Forest Domain>\Mailbox servers"

Add-AvailabilityAddressSpace -Forestname ContosoForest.com -AccessMethod PerUserFB -UseServiceAccount:$true

(b) To configure bidirectional cross-forest availability, repeat these steps in the target forest.


If you choose to configure cross-forest availability with trust, and also choose to use a service account (instead of specifying organization-wide or per-user credentials), you must extend permissions as shown in the example in the "Use the Shell to configure trusted cross-forest availability with a service account" section. Performing that procedure in the target forest gives Mailbox servers in the source forest permission to serialize the original user context.
(c) This example configures trusted cross-forest availability with a service account.
Get-MailboxServer| Add-ADPermission -Accessrights Extendedright -Extendedright "ms-Exch-EPI-Token-Serialization" -User "<Remote Forest Domain>\Exchange servers"

This example sets the organization-wide account on the availability configuration object to configure the access level for free/busy information in the target forest
Set-AvailabilityConfig -OrgWideAccount "Contoso.com\User"

This example adds the Availability address space configuration object for the source forest.
$a = Get-Credential (Enter the credentials for organization-wide user in Contoso.com domain)
Add-AvailabilityAddressspace -Forestname Contoso.com -Accessmethod OrgWideFB -Credential:$a

Four things needed to get you started:

1) Obtain a X.509 certificate from a Trusted Root CA (GoDaddy, Entrust, etc) for use with Microsoft Federation Gateway (MFG) for signing and encrypting delegation tokens.  (more here). Here is a list of Trusted Root CAs that MFG is aware of here.

2) Create a Federation Trust using cmdlet with the MFG (more here):

New-FederationTrust

3) Provide domain ownership by creating a DNS TXT record similar to (more here):

Contoso.com IN TXT AppId = 1C2

4) Add your SMTP domains (other Exchange Orgs) and add Federated domains to trust calendar information with (other org must accept) using cmdlet (more here):

Set-FederatedOrganizationIdentifier  - to enable your SMTP domains for federation sharing with the MFG

Add-FederatedDomain – to add other External Orgs to share calendar information with
