  PLESK_WARN: After upgrade you have to add write permissions to psacln group on folder C:\inetpub\mailroot\pickup. Please, check https://support.plesk.com/hc/articles/213914325 for more details.

Cause

Permissions for some folders (e.g. C:\inetpub\mailroot\pickup) were customized in order for certain applications to work.

Resolution

Connect to the server via RDP, create an additional file with custom rules and put it into the %plesk_dir%etc\DiskSecurity folder, as described in Plesk Advanced Administration Guide.

Below is an example of how to add permissions to psacln group on folder C:\inetpub\mailroot\pickup:

1. Connect to the server via RDP.

2. Create a file with the xml extension, e.g. permissions.xml in %plesk_dir%\etc\DiskSecurity\ with the following content:

   CONFIG_TEXT: <?xml version="1.0" encoding="utf-8" ?>
   <Entries>
   <Entry AccounType="1" Account="Psacln" Path="C:\inetpub\mailroot\" SubPath="pickup" AceFlags="ThisFolderSubfoldersAndFiles" AccessMask="FullAccess" EntryFlags="0x0" />
   </Entries>

3. Run the ApplySecurity.exe utility:

   C:\> "%plesk_bin64%"\ApplySecurity.exe --apply-to-directory --directory="C:\inetpub\mailroot"
