Synchronization of public folders after changing the account used for the Synchronization Service

Problem:

How to synchronize public folders after you change the account used by the Synchronization Service of CodeTwo Exchange Sync.

Solution:

The most frequent cause of an erroneous synchronization between personal folders and public folders is the lack of appropriate permissions. This manifests itself in the log files in the following way:

Error: Failed to copy an item "Calendar\Daniel" to folder "Firm Calendar in Public Folders". 
Failed to save changes. MAPI_E_CALL_FAILED (0x80004005)

Such situation may occur if the account under which the Synchronization Service runs has changed.

Use the guidelines below to learn how to give permissions to edit and delete items in public folders to a user account in Exchange.

   If you use Exchange Online (Office 365), you need to connect to your server via  Windows PowerShell instead. You can use these guidelines.

2. Type the following command to update a chosen public folder:

   Add-PublicFolderClientPermission -Identity "\folder_name" -User "user_name" -AccessRights EditAllItems,DeleteAllItems

3. Repeat the procedure for all public folders synchronized with CodeTwo Exchange Sync.

You can also grant the permissions to edit and delete for the root folder in public folders. To do this, type the following commands:

Add-PublicFolderClientPermission -Identity "\" -User "user_name" -AccessRights EditAllItems,DeleteAllItems

Alternatively, you can apply the settings to all your public folders:

Get-PublicFolder -Recurse | Add-PublicFolderClientPermission -User "user_name" -AccessRights EditAllItems,DeleteAllItems
