hello,

since 1 month time, i'm using outlook 2016 on my mac with my office 365 exchange account. 

i have more or less 3 gb mailbox. when i added my account to outlook 2016 it starts to give fault about downloading the attachments. 

now, even my new received e-mails randomly system does not download the attachments. i can reach the attachments from web mail office 365 but outlook can not download it. 

i thought that there is download limit but not, sometimes i can received big files without problem. but sometimes i didn't. 

the attachments shows as grey as in the photo and i can not forward these e-mails. system blocks itself.

could you please help me to solve this problem, 

it is very important,

I am currently using Microsoft Outlook for Mac, version 15.40 (171108).

I've had this happen a few times, I have had luck deleting the cache of the affected Inbox. I know this may be required when an error pops up with code -17890 on the Sync Errors page. All but once has rebuilding the cache fixed the issue, the one time it didn't work I used OWA to download the attachment but it turned out to be corrupt.

This isn't very efficient because rebuilding the cache requires a full download of your Exchange account, if you could delete the cached version of the affected e-mail it would be more efficient.

Follow the steps below to clear the cache of the affected folder:

  1. Connect to your fastest network connection, you may be downloading gigabytes of data.
  2. Open Outlook.
  3. Right click (or Control click) the Inbox of the account having the problem.
  4. From the pop up, select 'Properties...' near the bottom.
  5. On the 'General' tab you will find a button named 'Empty Cache', click it.
  6. Close the window if required.
  7. Your local copy of your Inbox will be deleted, a fresh download of all e-mails will be performed.
  8. From the 'Window' menu, select 'Sync Status' to monitor the process.
  9. Monitor the 'Sync Status' window, you will note several download threads receiving downloads.

Depending on how much mail is in your Exchange profile and your internet speed it can take 10 minutes or more to recover your Inbox contents.

OK, So I had this issue on another Mac yesterday.

Checked for updates on Office and there was about 1.6GB of them!!!!

Ran them all and the problem seems to be sorted for now.

Only time will tell as this issue is VERY random!

    Hi All,

    As this thread is an aged one and the scenarios are different (such as Outlook versions), to ensure you get dedicated assistance, please post a new thread with detailed information in our forum.

    Thanks for your understanding.

    Regards,

    Robert

    Hi Robert,

    This thread has been going on for months without MS providing a fix: reinstalling Office, deleting profile, creating a new one, blahblahblah ... nothing is fixing this issue.

    So, instead of asking us to start a new thread (why? so that this one can be closed? to improve the team's stats?), why do you ask your colleagues to provide us a real fix to this really annoying issue?

    Best regards,

    Hi BlahBlahBlahBlahBlah_,

    Thanks for the updates.

    As you can see the thread dated to February and Outlook for Mac has updated several versions. By posting a new thread, other community members can easily search the thread if they have the issue in the same Outlook version and also you will be assigned with a dedicated supporting engineer to troubleshoot the issue. Thanks for your understanding.

    Regards,

    Robert
