Exchange problem

[delanvital]

Hi all

I have been assigned at work with ensuring our move from RDP to O365. So far so good and today we did the DNS-switch on the Exchange, i.e. MX-records. I've run into a problem getting the old mails, contacts and calendars out of the old Exchange. :sad:

What the company helping me forgot to mention, is that all the local Outlook installations in the RDP should have had cache/offline storage enabled. They do not. This means that the old mails can be seen only via OWA (outlook web access) to the old exchange server, but from there I can't get the old mails, calendars and contacts "out" since that function doesnt exist.

My original plan, which I was told would work, was to log into the local Outlook installations on the users RDPs, after the change had taken place, go to advanced settings, and do an export to PST of mails, calendars and contacts. Since these Outlook installation can't start, since it can't find the Exchange server, because of the DNS change, I can't access the old Outlook anymore, and thus not make a PST-transfer.

I need now to either

- switch DNS back (shudder, what chaos)
- somehow get around this (what do I need to get into the Exchange server?) or
- talk with our company which we have cancelled the agreement with.

They are not happy with us moving, let alone moving to O365, so I fear they will charge me a FORTUNE since all those GBs does that lots of hours to get out (not that you need to sit and stare at it, but I am in a bad position to argue). I had thus hoped to bypass them totally, and now I'm ****ed.

Any ideas greatly appreciated :sad:

PS: My outlook install on the server was running when the switch took place, so I have access to that still. It moans a lot, but so far I've had luck with exporting my own mails. I can also see the server settings there, which I have tried to copy to a local Outlook install, but it fails just like the RDP Outlook install, I guess because of the DNS-change.
