Since PN are hiving off their email business to Greenby, is there any chance Greenby might be motivated to help? Wanting to make a good impression on their enforced new customers? Or is that just wishful thinking?

[#2]

@Hortense Greenby are a hosting company - I doubt they would have the experience or clout to influence MS.

[#3]

I meant, to influence PN, not MS!!

[#4]

If Greenby have any sense they'll have their lawyers combing their contract with PN to find out how to walk away from having to take on a crippled system that will haemorrhage existing customers at a rapid rate and not be able to attract new ones.

They might have a case too, since it appears from what has been already said in this topic, that MS announced their intentions many weeks ago and PN did nothing in response.

Plusnettony is on vacation - it’s not a case of Plusnet dragging their feet.

It is clear that there are many around here who do not understand the challenges of making significant operational changes where the requirements are unclear.

From what is known about the future, the migration will not alter the scope of the required fixes to accommodate Microsoft’s foul up.

Your inflammatory comments are helping no one.  Please stop stirring the pot.

[#7]

OK but the repetition of, "It's all MS's" fault is not helping either.

[#8]

If PlusnetTony is away, surely letting us know that would have been helpful and also why isn't somebody else from Plusnet taking this up? It's really nit good enough to keep blaming MS whilst apparently doing nothing. If something is being done then let us know so we can at least feel we are not being abandoned. 

[#9]

“Apparently” that is the point here, you know nothing and inflaming the discussion helps no one.  As Tony advised the issue is with the incident management team.  Anyone who thinks this is a simple fix just does not understand the problem inflicted by a third party.

As someone that works in IT I share the PN technical teams frustration in MS behaviour, and appreciate that they cannot simply do a bulk config change overnight without thorough testing first, not to mention they likey aren't the only parties impacting by this change and may find MS are generous enough to make an exception.

Likely they wouldn't want to spend hours of technician time doing something that MS then duly reverse anyway.

Yes, I was wondering how this affects domains such as ...sch.uk and ...nhs.net ? They make extensive use of subdomains and AFAICS the parent domains aren't registered as a tld.

[#12]

The first thing I did when I realised the severity of this to potentially 1.5 million PN customers and as a result PN itself, was to write to my MP. (who is investigating it). Whether anything comes of this and how quickly on time will tell.
Perhaps other impacted PN customers should take this approach. If anything, this has given me the satisfaction that I have tried to do something about it.

Thanks, that's a good idea. I'll do that as well.

I do share frustration with all of this. It would be nice if plusnet could provide updates. Waiting for Microsoft is not an option.

I further think it is unhelpful how people on here are attacking frustrated users rather than pressuring plusnet for a fix.

Plusnet are a business, owned by an even bigger business, probably the biggest in the UK. They are not a bunch of amateurs - if they were I would have some sympathy. Frankly, it is their job to monitor email developments in the sector - I would suggest that Microsoft saying they are going to require XX for large volume domains should have at least made PN think "this might affect us, let's do some due diligence" rather than doing nothing. Saying why would they want to spend time fixing this if Microsoft come and fix it anyway is ludicrous.

I think PN should consider compensating users for this.

[#15]

I completely agree about Plusnet acting responsibly by keeping e-mail users briefed with resolution plans and progress. This is not some from of cosmetic service issue that is of little consequence, it is a significant e-mail issue!

Plusnet would do well by sending out e-mails to the accounts of those using the service to keep us briefed and would satisfy users' desire to directly see that the problem is being taking seriously.
