Sun, 05 Apr 2026 16:40:36 +0000 https://bugs.horde.org/ticket/14509 No Mail via Activesync with IMAP I use Horde Version 5.2.16. I use a lot of mobile devices synced over activesync. Everything was working fine till i updated via PEAR at the beginning of November 2016. Syncing Mail stopped since then. I did some research and debugged activesync. There was an error that UIDVALIDITY is no longer supported with IMAP. In the errormessage there was a typo UIDVALIDTY. I searched my sources and found PEAR/Horde/ActiveSync/Imap/Adapter.php a changed file. I changed the file at line 334 from -- Adapter.php -- $status_flags = Horde_Imap_Client::STATUS_HIGHESTMODSEQ | Horde_Imap_Client::STATUS_UIDVALIDITY | -- Adapter.php -- to -- Adapter.php -- $status_flags = Horde_Imap_Client::STATUS_HIGHESTMODSEQ | //Horde_Imap_Client::STATUS_UIDVALIDITY | -- End Adapter.php -- With this change activesync is working again on all my devices.
