My first post. I could not help but set up my user account and reply as this has been driving me nuts.
iPhone 4S and iPad 2 both now with 5.1 iOS.
Same thing, where did the Mail Days To Sync No Limit option go.
Through much painstaking dead end research, I think ai have a conclusion on my end.
I use GoDaddy exchange email and I believe they have pushed a server restriction out on the users. I have not got them to admit this as their support in exchange dept says they have had other calls on this but get no answers from the engineers or devs.
This appears to be the source as this option still exists with other accounts so it cannot be an iOS thing.
I have found a workaround, at least for the moment my entire mailbox, subfolders and all, appears to be operating under the no limit rule, which is a necessity for my business. How could anyone think restricting this option without reporting such to the customer is a good idea?
I'm not sure which one did the trick but here are the steps I used to get it back functioning. It was a little more stubborn on the iPad because every time I wold recreate the account, it defaulted to 3 Days.
Step 1: toggle off SSL in account settings. It warns you that you may not be ale to send or receive email after it fails to verify your account (at last with GoDaddy Exchange). Save in this state anyhow. You will notice your mailbox disappears. Go back into options and turn SSL back on. Check Mal Days To Sync. On iPhone it defaulted to no option selected. Leave like this! It is the equivalent of No Limit. As soon as you select a limiting option it can not be undone, unless in theory you repeat these steps.
Step 2: On iPad this did not do the trick because it kept defaulting to 3 Days option. Do not delete your exchange account, but rather de-select Mail option from syncing. This blows out your mailbox but the option for no limit returns. Select No Limit. Turn mail back on.
Step 3: forget this ever happened and go back to enjoying your older email messages on your mobile devices.
Please post feedback if this worked for you. I could not find anything on this anywhere so felt obligated to share. I'd like to see if it helps anyone with the same issue.
Also please state in reply who hosts our exchange server. It would be interesting to see if it is GoDaddy across the board.
Thanks for reading!
