I am using the last version of NextCloud AIO and Mail app When opening my inbox (using Stalwart), it is taking forever to display the inbox Sent Items is instantanous Any advice ? Nextcloud AIO v12.5.0 I know AIO is may be not supported but it’s may be a NextCloud / Mail app configuration (tweaking) that is needed and I am taking a chance to ask here Inbox has over 7000 messages Thunderbird can open it without problem. ---

Well - 7000 message take a while to load. I don’t know the code of the Mail app - but maybe it is not caching the message view but always reloads all messages when opening the Inbox. For browser based mail access I prefer Roundcube - that works fine even when opening folders with many messages as it caches everything in its database. The reason why Thunderbird is faster is the same - Thunderbird does not load the messages it already has. So even if the Inbox has 7000 messages, Thunderbird only loads them once and will later only request new messages when opening a folder since the last time it connected to the server. ---

I Deleted my account in Mail I vi /usr/local/etc/php/conf.d/nextcloud.ini I changed the memory\_limit = 512M to memory\_limit = 1024M. Inbox is now working well ---
