We have long since completed our mailbox migration with Priasoft. The software has been uninstalled and everything is fine and working well, however there are some residual Priasoft objects left on our Exchange servers.
Priasoft attributes are left in user’s email address properties, such as x500, NTSID smtp GUID’s and so on. Is there an easy way to remove these attributes from Exchange?
Unwanted additional email addresses can be removed with powershell commands from Exchange.
Note that X500 should never be removed as this is a critical value for Exchange and supports the ability to reply to old messages.
The NTSID and NTUSER properties reflect the original source user account. They were used to support the ability to re-apply folder and mailbox permissions. These can be removed without concern. However, bear in mind that if sometimes being able to access the original SID or domain/username values can be helpful in sorting out other issues, even ones that occur outside of the Exchange context. For example, if an application had originally stored user SID values in its internal database for some sort of mapping, and there was a need to update that database, having the original SID of users preserved on the accounts can help facilitate such an update.
Values such as HASSOBD and HASDELEG can be removed without concern as well and were only used by the migration and are related to folder permission updates.
Priasoft doesn’t provide any utility for such cleanup, but such actions are not difficult to perform with powershell. Look towards the Set-Mailbox powershell cmdlet to manage email addresses.
