Surprised no-one has reported this problem (a search didn't reveal anything)
Since upgrading to the latest OS I was having nightmares sending e-mails, kept getting the message "there was an interruption in sending this message please try again" and then message had a red cross next to it
Kept trying to re-send and then had the same issue
Then I got mocked my iPhone toting friend asking why my playbook had e-mailed him 5 times
After some repeated googling, it appears that there is an exchange bug in the latest OS, where it sends the e-mail but flags it as failed. Then it keeps trying to re-send the e-mail
Current solution appears to be to send the e-mail and then delete it from the in-box (but then you don't have a record of any sent e-mails and you don't know for sure if it was sent)
Is anyone else having the issue, I can't be the only one with the problem!
Turns out there is a fairly old thread on on the playbook support forums that I've woken up, and RIM have allegedly acknowledged the issue, but wont fix it until the next OS release
I had this too... I called RIM and they said it was my email provider (I have hosted BES). I called them and changed to imap for email and left activesync for calendar and contacts... Seems to have fixed it.
