Remap existing retention labels on emails

[ellan1537]

There are tons of emails in multiple users outlook (M365) on which Retention Labels were applied. We've came up with a new set of retention labels now.

Is there a script that can remap all the existing labels to the new ones by crawling through these emails?

Any help is greatly appreciated!

Thanks

After going over this with my team and Microsoft, seems like there is no option to do this exactly that way. Although, you could use the Purview’s Content Search to get a report on Retention labels applied in Exchange.

These are the M365 Retention Labels, not MRM tags.
