I'm not sure if this is the correct place to post this question, apologies in advance.
Environment -
- Outlook 2010 (installed on terminal server, however same issue occurs when installed on local workstation)
- Cached Exchange Mode Off i.e. Online Mode (Reasons being related to the delay experienced when using the Search Functionality)
- Office 365 E1 licenses
- Users have multiple mailboxes open
I'm having delays with changing between mailboxes. For example, I'm attempting to change between a shared mailbox and it's taking anywhere between 5 to 10 sec (30sec in extreme cases).
There too is a delay (between 5-10 sec) when attempting to perform the following;
- Moving the email (where it be a test email [minimal size] or very large) from any Shared Mailbox to my personal one.
- Deleting the email from the shared mailbox
What we've ascertained;
It is not the internet connection (getting a consistent speed of 15Mbps on average down / 1Mbps on average up)
It is not the workstation as well as this is occurring across all platforms (local and terminal)
If I have missed anything, please let me know and I'll answer promptly.
Thank you,
Robin
