Fasthosts Exchange 2010 to 2019 Email Migration

From the 24 February 2020 Fasthosts our hosting provider have started to migrate legacy mailboxs that they have hosted on their Exchange 2010 system over to Exchange 2019 as support for Exchange 2010 ended on the 14 January 2020.

The legacy mailboxes that being migrated are: Exchange 2010, Starter, Starter Plus and Professional.

Mail Lite and Mail Extra mailboxes do not use Exchange so they are not affected by the migration.

Exchange 2013/2016 mailboxs are not migrated automaticly but please contact us for upgrade options as there is a price/storage space change for upgrading the mailboxes.

If your email is hosted on Office 365 or G Suite (formaly Google Apps) you will not be affected by this migration as it is not a part of Fasthosts.

To find out what mailbox type you have, login to
Your username is your email address and the password is the one that we provided to you when we set up the email account. If you do not have this handy we can do a password reset for you if you contact us.

Migration of mailboxs can take up to 72 hours once started but most of the time it is quicker than this. Durring the process your mailbox might become unavailable for a short time.

After the migration you may need to update your email client settings and/or reinput your password.
Some users would have a new webmail client to use which can be accessed via
Some older email client software might not work due being obsolete. More details are further down this page.
