What is the MX propagation time?

Hello everyone,
My domain name is: metawebsolution.com
And I use the offer: Hosted Exchange

I have the following problem :
I made the first settings in my offer, but my domain is in another OVH account (they are different companies, but from the same group).

Even if I have configured the MX and SRV that the platform guides me, they still appear in red, indicating an error.

How long does this verification take? Is there anything else I need to do?

Thanks if anyone helps me.!Captura%20de%20ecr%C3%A3%202023-07-27%20095035|690x26!Captura%20de%20ecr%C3%A3%202023-07-27%20101140|540x169!Captura%20de%20ecr%C3%A3%202023-07-27%20101220|690x170

Hello,

The propagation time can be up to 24h after the modification in the dns zone.
