Please note, that the current e-mail server (ipnp.mff.cuni.cz) is being discontinued by the end of February 2024. After this date, emails addressed to the old mailbox will be forwarded, but you can no longer access the old mailbox. All university employees have access to the central mail server (matfyz.cuni.cz) which can (should) be used as a replacement. If you wish to transfer your old e-mails from the old mailbox (ipnp.mff.cuni.cz) to the new one (matfyz.cuni.cz), please follow the instructions from this page.
You are advised not to leave this task to the very last minute. The procedure required to transfer the old emails is quite complicated and cumbersome and requires a lot of time.
