Warning Event 9327 from MSExchangeSA

In this case Warning Event 9327 from source: MSExchangeSA was logged in Application Event log on Exchange 2010 server responsible for OAB generation by default every day on 5 AM:

Log Name:      Application
Source:        MSExchangeSA
Date:          12/1/2014 5:04:50 AM
Event ID:      9327
Task Category: (13)
Level:         Warning
Keywords:      Classic
User:          N/A
Description:
OALGen skipped some entries in the offline address list '\Global Address List'.  To see which entries are affected, event logging for the OAL Generator must be set to at least medium.
- \Default Offline Address List

By default, event logging for the OAL Generator is set to lowest level. In order to see why some entries are skipped by OAL Generator, event logging level must be set to at least medium. One way to set this requirement is by using PowerShell :

Set-EventLogLevel -Identity "ExchangeServerName\msexchangesa\oal generator" -Level Medium

Setting the logging level to Medium for the OAL generator will produce a lot of events during the generation of OAB. Informational events generated from MSExchangeSA with Event ID 9359 can be safely ignored, but error events with id 9325 are the one that are triggering the event id 9327 from MSExchangeSA. For example:

Log Name:      Application
Source:        MSExchangeSA
Date:          12/25/2014 5:04:03 AM
Event ID:      9325
Task Category: (13)
Level:         Error
Keywords:      Classic
User:          N/A
Description:
OABGen will skip user entry 'John Doe' in address list '\Global Address List' because the SMTP address '' is invalid.
- \Default Offline Address List

John Doe was not having email address, but was having "ShowInAddressBook" property populated. So, in order to fix this behavior, I've created mailbox for this user, and after that immediately disabled the mailbox for this user, and all exchange related properties were cleared from this user.

Now, return (set) the event logging level for the OAL generator to default (lowest) value:

Set-EventLogLevel -Identity "ExchangeServerName\msexchangesa\oal generator" -Level Lowest

And, warning Event 9327 from source: MSExchangeSA was not logged in Application Event log on Exchange 2010 server responsible for OAB generation in 5 AM.
 

Setting calendar permissions in Exchange 2010

This is quick post for reference, and is intended to show how to manage user's calendar permissions in Exchange 2010. Four PowerShell cmdlets are available for achieving this task:

• Get-MailboxFoderPermission
• Add-MailboxFolderPermission
• Set-MailboxFolderPermission
• Remove-MailboxFolderPermission

For example:

• To list (get) assigned calendar permissions on user Jane.Doe here is the syntax:

Get-MailboxFoderPermission -identity jane.doe:\calendar

• To assign John.Doe Reviewer permission on Jane.Doe calendar (John does not have any permission on Jane's calendar):

Add-MailboxFolderPermission -identity jane.doe:\calendar -user "John Doe" -AccessRights Reviewer

• To modify already assigned permission to John Doe on Jane Doe calendar from Reviewer to Editor:

Set-MailboxFolderPermission -identity jane.doe:\calendar -user "John Doe" -AccessRights Editor

•  And finally to remove already added permission for John Doe on Jane Doe calendar:

Remove-MailboxFolderPermission -identity jane.doe:\calendar -user "John Doe"

 

Nokia E72 stopped synchronizing emails

In this case my friend's "oldie" phone Nokia E72 stopped synchronizing emails using ActiveSync. He was also unable to access his mailbox using outlook web access link.
The reason for this behavior was that the company's IT has replaced expiring certificate with new one (nothing odd here), but the new certificate was having sha256RSA signature algorithm. Nokia E72 was unable to access https web sites secured with sha256 certificates.
In order to fix this behavior fortunately there is a fix which will enable Nokia E72 to successfully access https web sites secured with sha256 certificates. You can download this fix from http://dl.nokia.com/ns/symfix/networking_improvements.SIS .

After installing this fix for Symbian, my friend was able to synchronize email using ActiveSync again, and started to open https web pages secured with sha256 certificates.
