3 * Mailspring (Android, MacOS, Linux) accessing same IMAP mailbox -> lost mails

Hej,

I am using Mailspring on MacOS X and Android and recently added Mailspring 1.16.0 on Ubuntu Linux. All accounts use the same IMAP mailbox.

Unfortunately it seems that this setup results in lost emails: my “Inbox” is different depending which client I am using:

  • Deleting mails on Android will still show them on Mac OS X
  • Mailspring Ubuntu misses an entire month of emails (January, approx. 350 mails) - there is just a gap between December and February
  • I do not see emails on Mac OS X which I see on Android or Linux

Is accessing the same Mailbox from multiple Mailspring not supported?

Thanks
