DKIM lookup tools showing error for Selector 1

Dear Forum,

I just wondered is anyone else is seeing the same issue where checking domain DKIM selector1 with i.e agari or dmarcian and I guess other lookup tools, where it shows “DKIM record is missing” or that there is something wrong with the record when in fact they are setup correctly. Checking Selector 2 they all report ok and if I use the MS 365 Powershell command “Get-DkimSigningConfig | fl” It shows both selectors are working so I assume all is working ok. I notice Microsoft have recently added support for 2048-bit encryption keys so maybe this is the reason as the selectors rotate they will be upgraded.

Anyhow If anyone else has noticed the same I’d be interested to know

Kind regards
Kevin
