Want to set Retention tags with EWS?

  • Artykuł

I put together some information to help with writing code to set retention tags on a folder.  The articles at the end will go over how the retention properties are used in code, one has a sample which shows setting the retention tags on a folder using PowerShell and the EWS Managed API and the last is to a Microsoft MVP blog where there is a large quantity of samples which you might be able to leverage.

EWSEditor has code in it which can set tags on a folder – you can access that functionality by right clicking on a folder (FolderRetentionSettings.cs).  You will need the policy GUID from ECP in order to add a tag. Under the Tools menu is a window which will show the policies for a mailbox (UserRetentionTagPolicyTagsForm.cs) and also let you search mailbox to see where a tag is applied.  The full source is downloadable.

Note: You will need to alter this sample per your needs. Be sure to change out the GUID used with the one for the policy from ECP.

Glean Scales blog – It has a lot of Exchange PowerShell script samples which use the EWS Managed API.
