I'm posting this so we don't use anymore space in the original Two Exchange Account thread.
Discuss/report issues/feature requests/etc
Description from Cydia:
This app will add a second Microsoft Exchange account to your iPhone or iPod Touch. Please do not try use it to add more than one account. Enjoy
To use hit the plus button in the app and wait for the dialogue to appear that it is finished. Then go to Settings > Mail, Contacts, Calendars > SRV2 and edit that to your second account's needs. To Uninstall press the red uninstall button. || Built for OS 3.0+ || Thanks go out to the community at #iphone on irc for all the help on this app.
Credits to drivesoslow for the mod.
The uninstall feature is in update 1.1 which should be live within 24 hours. At the moment it comes without it.
Battery life is decent with just 2 accounts which is how it works now. Also I am working on 2.0 and have finished a 1.2 update which fixes a spelling error and a settings error while adding the account.
EDIT: sent out an update that includes Multi-Account support. (v1.5)
I have been using this with 2 exchange accounts for sometime, but have noticed a problem lately. I encounter some bizarre behaviour where the unread message count will be incorrect, or a message that I have read will remain unread, or will change from read to unread. This happens for each account and does not reflect the true message status on the server as viewed through outlook, or outlook web access. sometimes when I launch the mail app, the messages will download again as though it were the first time synchronizing with the server.
I reset the app, uninstalled an reinstalled and still have the same problems.
