Firstly, please forgive me if this question has been asked before!
We are a very small office with 1 email address and a simple website and I am not an IT technician but I seem to have been allocated the IT function (issues).
Prior to me starting with the company, the website domain was hosted at www.123-reg.co.uk and an email was also created using the domain name.
The company was using Office 2010 (Outlook 2010 for email utilising IMAP) and Small Business Server 2003.
I have recently replaced the server to WSE 2012 and also managed to convince my manager to switch the Office Suite and email to Office 365 Business Premium.
I have registered our domain with O365 and the email is working fine with all new emails coming through O365. The website will remain with 123-reg.
The issue that I have is the email that is still on the server with 123-reg.co.uk. The inbox and sent items that are still on the 123-reg server have approximately 12500 emails that we want to be able to move over and access using O365.
As a non-techie, I looked online and found an option to do an IMAP migration which I thought would do the job. I tried it but it simply would not work, saying the migration had failed.
I would be really grateful if anybody could advise any way of moving the old emails across to O365...but preferably an easy(ish) and free way!
