Since SSO with Salesforce is case sensitive you need to get the information directory form the Domain Controller
Logon to Domain Controller
Import-Module activedirectory
Get-ADUser -Filter {EmailAddress -like “*lastname*domain.com”} -Properties EmailAddress | Select Name, EmailAddress

Error after a fresh installation of SSRS:
User domain\user does not have required permissions. Verify that sufficient permissions have been granted and Windows User Account Control (UAC) restrictions have been addressed.
1 Launch IE using “Run As Administrator”
2 Click on Site Settings > Security and add your user domain\user as a System Administrator
3 Click on “Home” and the Folder Settings. Add the user to all roles (Browser, Content Manager, My Reports, Publisher, Report Builder)
In our situation, after a mailbox migration from one database to another database, the mailbox was flagged as quarantined by Exchange. This looks to be a feature added in Exchange 2010 to prevent a single mailbox from taking down the entire information store.
To verify the mailbox is quarantined you can check the registry on the Exchange server.
Get-MailboxStatistics – Identity user | fl IsQuarantined
OR
HKLM\SYSTEM\CCS\Services\MSexchangeIS\Servername\Private-dbguid\Quarantined Mailboxes\ {Mailbox GUID}
To get the Mailbox GUID
Get-MailboxStatistics – Identity user | fl
To get the Database GUID
Get-MailboxDatabase -Identity database | fl guid
Reset the quarantined mailbox by deleting the quarantine registry key for that mailbox.
The database has to be dismounted and remounted OR the Exchange Information Store service needs to be restarted for the change to take effect immediately. If the error still exists, the mailbox could crash the store and become quarantined again.
