Exchange 2010: Public folder GUID

One of the Event in the Application log in Exchange 2010 is showing the following event 

Event id : 2028
The Delivery of a Message sent by Public Folder E0FG2CADACE66846A98A6C130CA3ER97-0000FA965FG85
has failed.\r\n To:first name, Last name\r\nCc:\r\n The Non-Delivery report has been deleted


Steps
---------
Getting which public folder is in picture finding is difficult here. 
so if you had tried this then it will not work and through's error

c:\>Get-MailPublicFolder -id E0FG2CADACE66846A98A6C130CA3ER97-0000FA965FG85 

is not showing proper error and message shows it couldn't be found



so instead of running the command using the whole Hexa-Decimal value, use the value before dash ( - ) so here in this example "E0FG2CADACE66846A98A6C130CA3ER97-0000FA965FG85"  we are going to use E0FG2CADACE66846A98A6C130CA3ER97 and to convert this value into proper GUID use the following command from Exchange management shell



c:\>[system.Guid] 'E0FG2CADACE66846A98A6C130CA3ER97'
Guid
--------
E0FG2cad-ace6-6846-a98a-6c130CA3ER97

and finally the command for getting public folder is 
c:\Get-MailPublicFolder -identity E0FG2cad-ace6-6846-a98a-6c130CA3ER97

or 
c:\Get-MailPublicFolder | Where {$_.LegacyExchangeDN -Match "E0FG2cad-ace6-6846-a98a-6c130CA3ER97"}



or using with complete GUID then you can use below command

[PS] C:\Windows\system32>Get-MailPublicFolder -resultsize unlimited | where {$_.Externalemailaddress -match "0ED914CAB4DA1243948B9AD6B0B27FDE-000000000014"}


Or to reveal the name of the public folder use the below command
[PS] C:\Windows\system32>Get-MailPublicFolder -resultsize unlimited | where {$_.Externalemailaddress -match "0ED914CAB4DA1243948B9AD6B0B27FDE-000000000014"} | Get-PublicFolder 

PS: Guid used here is only for illustration purpose only.

Exchange 2013 SP1 There are 3-4 users getting dual archive mailbox

Issue :

1. Users are in Outlook 2013/Outlook 2010 and OWA, few users are getting dual Archive mailbox

2. For the same user, Inbox is visible in Archive Mailbox, both from Outlook and OWA

Resolution :

1. Test-E-mail Autoconfiguration" from Outlook shows that the Outlook is connecting to another users Mailbox and Full mailbox permission is added for another user's Mailbox in the user mailbox


Removing full Mailbox permission for another user mailbox from the original user's Mailbox resolves the issue


2. When Archive Mailbox is enabled for user, Exchange will copy the frame like inbox, sent and delete Item etc but will not publish until data is moved to Archive mailbox via Retention Policy
