Hi there and welcome Simon
Can you tell me what advice exactly you need please? Or you need help setting it up to use across multiple devices?
First, you need all 40 accounts on new computer?
ok, first you have to add the accounts to the new computer, this you cannot avoid else there is no way for them to get on the computer
Are the emails for these accounts stored on the email service Simon?
No it cannot store this else it would be too easy for people to obtain, you will need to get the passwords for these accounts, but you should always have these safely kept.
But you cannot get these from outlook.
nearly all email services though have a password ***** link on their site or a department to reset this, so you would need to go through and do this for the accounts you have no access to.
Ok, OST is only with Exchange or iMap, it is the way to go but only if your email service provide has this functionality, then when you make folders it make them on the server and it is shared across multiple computers, this is the only way to achieve this, it is via iMap.
What you do is if you can connect using iMap, then you add the account on the old computer via iMap, then drag the folders to it, it will then upload the folders to the server.
Then when the second computer connects, you connect it also via iMap and it will download the folders as well, not just the inbox which is what you get with Pop3 (that you currently have)
Another way is to add the accounts on the new computer as iMap accounts, then copy over the PST files to the new computer.
Then go to File, Import and import the PST files into the account. Either way will accomplish this.
ok, Gmail does do iMap. The only other way would be to copy the PST between the computers and manually import. It is not ideal but this is the whole reason iMap was invented, to share information for all folders ect between multiple computers.
If you would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
Yes, you should try to minimize the amount of accounts as much as possible. And you should use iMap so you can forget about PST's and backing them up.
Office 365 will not back up the PST to the cloud, you need to do this manually yourself or better yet use iMap
