All of our users experienced the 'corrupted IMAP UID', resulting in each IMAP client having to redownload each and every IMAP email (Gigabytes worth). Of course as many users were affected, these downloads had to keep restarting and would not complete as Zohos bandwidth was saturated well beyond capacity.Since it corrupted the IMAP UID, it resulted in complete resync of data for impacted IMAP users.Though we identified the issue and corrected it before the impact affected all IMAP users, we could not do much to help the first batch of users who were affected.
Now to me this would indicate that at this time Zoho did not know what the problem was and had not fixed it. It was not until 2 days later that users were informed that the problem was fixed and corrected before it affected all users (see above).We acknowledge that there is a technical glitch in connecting to our IMAP Servers for some of the users. Our technical team is looking into this with highest priority.Until we fix this, we request you to access your emails from the webmail (mail.zoho.com) or from the mobile browsers (t.zoho.com or m.zoho.com) to access from your tablet or mobile devices.
As some further information, five days after this disaster, and well
after it was 'fixed', I started a client that had not received
any sync with IMAP since well prior to 30th Nov when the disaster
(migration) started. This client, although started well after the
comments "fixed... before it affected all IMAP users",
experienced exactly the same problems as those turned on within the
first day of the disaster. This in itself calls into question the
accuracy to the zoho staff post.
Because there is a lack of transparancy in what Zoho are doing, it is guesswork for zoho customers to know what is the real truth on this.
As such I seek to find out from Zoho, if they are willing to actually give some transparency, but primarily from zoho customers (with large IMAP mailboxes ONLY as small email users would not have noticed the redownload most likely) to find out who were affected by this IMAP problem.
We are extremely concerned that Zoho has not been honest in this problem, and for us that raises grave concerns. Especially when direct questions have been raised to them over this issue in regards to backups and disaster recovery that have been ignored.
So please zoho customers with large IMAP emails please put your comments here if you have been affected and how.
Also please thumbs up this post if you have been affected by this disaster.
