Bug?

Do you have any third-party plugins installed? If so, which ones?

No

Is the issue related to a specific email provider (Gmail, Exchange, etc.)?

Exchange

Is the issue reproducible with a particular attachment, message, signature, etc?

When moving messages to trash or archive with my university mail account (TU Berlin-exchange)
changes are not reflected/synced on the remote server.
This has been working in older versions, I believe < 1.0.3

Feature Request?

Does this feature exist in another mail client or tool you use?

Hmm this is interesting - this is probably what's happening in #335 too.

[bengotow]

Hey folks—I think we've figured this out in #364. Mailspring required the IMAP MOVE extension to actually place messages in the trash, archive, etc. and it seems a fair number of providers still don't support that extension. In 1.0.11, we'll fall back to the very old school approach of COPY, STORE, DELETE when the MOVE capability isn't available. It's a bit slower but should ensure that deleting / archiving messages works absolutely everywhere.

Sorry for the hassle—I actually hadn't seen an IMAP server that didn't support the MOVE extension, and the underlying mailcore2 library we use for IMAP was assuming it would always be present. I'm going to continue testing the fix but 1.0.11 should ship in a couple days.

Hey folks - this has shipped in 1.0.11. The app will download the update automatically, but you can get it directly here: https://www.getmailspring.com/download. Gonna go ahead and close this—if you continue to have trouble after the update, let me know and I'll re-open it!
