Email address is a mess

Hello KazzaB,

I would recommend you create a new Mail profile. Please, do the following:

1- Go to Control Panel and select Mail (Microsoft Outlook)

2- Under Profiles, go to Show Profiles

3- Then click on Add > choose a name  > click OK

4- Follow the Auto Account setup process

5- Proceed to signing in.

See image for reference:

Let me know if after this the issue is resolved. I would also recommend updating to the latest version of Office available.

Thanks,

Jose
