The tags are set on server, so changing servers likely is the reason you don't see the tags. Yes, the folder name can be changed. In doing so, TB creates a new folder with same contents, and you may find that the unified tool bar needs to be reset to include the folders.

Thanks @david, although tags are set by the server, once set by the server, they're on the email. This issue is not with tag setting, or even the tags at all - the issue is with Search Folders.

Search Folders seem to exist as files, like so: `[profile] > Mail > smart mailboxes > tags.sbd > [search folder name].msf` TB interprets those files in the UI as Search Folders which contain emails according to search criteria. That search criteria can include searches on tags - my Search Folders search criteria make extensive use of tags.

I changed servers, the emails on the old Gandi server were moved to the new MXroute server, including the tags in the emails. So, same emails on old Gandi server, same emails on new MXroute server; same tags on old Gandi server, same tags on new MXroute server.

Following the change of IMAP server in the email account - and the subsequent TB restart - the Search Folders that used to exist, no longer exist in the UI - however, the system files that TB interprets to create the Search Folders continue to exist here: `[profile] > Mail > smart mailboxes > tags.sbd > [search folder name].msf``[profile] > Mail > smart mailboxes > tags.sbd > [search folder name].msf`

The file contents before and after the move are the same (thanks Meld). Here's the contents for the file `bugs.msf` (for the UI Search Folder 'bugs'): ``` // < <(a=c)> // (f=iso-8859-1)

I do wonder whether this question might be better as a bug report - but, there such a wealth of places to post a question about TB (and FF for that matter) these days one doesn't really know which way to turn...

Yes, the folder name can be changed. In doing so...

How does one do so? From within TB; if so where? Or, in the file system - presumably with TB not running?

Thanks
