v2.5.0 - 2022-01-14

Added

New parameter DeleteScriptCreatedSignaturesWithoutTemplate, see README for details
New parameter EmbedImagesInHTML, see README for details
Tags can now not only be used to allow access to a template, but also to deny access. Denies are available for time, group and e-mail based tags. See README for details.
Consider distribution group membership in addition to security group membership
Consider sIDHistory in searches across trusts and when comparing msExchMasterAccountSid, which adds support for scenarios in which a mailbox or a linked account has been migrated between Active Directory domains/forests
Show matching allow and deny tags for each mailbox-template-combination. This makes it easy to find out why a certain template is applied for a certain mailbox and why not.
Show which tags lead to a classification as time based, common, group based or e-mail address specific template
New FAQ: Why is membership in dynamic distribution groups and dynamic security groups not considered?
New FAQ: Why is no admin or user GUI available?
